1 INTRODUCTION

The MultiCorr MKII is a software based, computerized, hand held corrosion meter and data

acquisition unit suitable for the interrogation of different types of corrosion probes. It is housed in a

rugged rubber coated housing that is splash resistant and intrinsically safe. Each MultiCorr MKII

can be individually configured to the user's specific needs at the time of purchase. Additionally, the

unit can have its software upgraded at any time to add Functions which were not included at the

time the unit was purchased.

Each MultiCorr MKII has the capacity to store up to 3,000 sets of readings. Readings may be stored

in memory along with a unique probe number, an alphanumerical tag designation, along with an

automatically generated reading date and time. Written records are not required, but can be easily

maintained.

1.1 Capability and Functions

The MultiCorr MKII is capable of monitoring a wide variety of corrosion probes, so there is no

read only ER Probes and take automatic readings or have an instrument that can read ER, LPR and

Galvanic Probes, take Automatic readings and perform Polarization measurements.

The MultiCorr MKII can grow with your operations since any Function which was not included

when the unit was delivered may be added at a later date.

MultiCorr MKII - User Manual Page: 7

1.2 Probe Compatibility

The MultiCorr MKII is a versatile instrument which accepts corrosion probes of different designs

and from different manufacturers. There are default settings within the MultiCorr MKII for each

type of probe, and the user can easily modify these settings so that any probe can be read regardless

of the manufacturer. Because of variations in the size and type of connectors it may be necessary to

have different cables for different manufacturers. When ordering, please specify the manufacturer

and probe type and CorrOcean will provide the required probe cables to suit the user's needs.

1.3 Data Transmission To PC

The MultiCorr MKII can communicate directly with any IBM compatible Personal Computer (PC),

which has been loaded with the CorrOcean Corrlist Software provided with the MultiCorr MKII. It

can also communicate directly with other CorrOcean Software programs such as CorrTrend and

CorrChart. CorrTrend is an advanced corrosion data management program and CorrChart can

be utilized to automatically plot and present polarization curves. Data transfer to the PC can be

performed using either direct data transfer cables or via a modem.

When used as a terminal, the data are transferred into the CorrOcean software MultiCom or

SandRater (for MultiLog and SandLog data respectively)

1.4 Manual Use and Information

This manual includes information on the use of every feature of the MultiCorr MKII Instrument.

The manual provides details on the use of functions which may not have been included in the

MultiCorr MKII purchased by the user. Any MultiCorr MKII function may be added to your

instrument after it has been purchased. Call the nearest CorrOcean office listed in the back of this

3 HANDLING AND STORAGE

3.1 General

The MultiCorr MKII is built into a rugged splash proof case and is designed for operation in an

offshore, industrial and/or hazardous environment. Carefully selected materials have been used to

meet these requirements. For example, the application of a silicone rubber cover on the bottom part

provides thermal insulation, shock absorption and a friction mantle. The silicone rubber can

withstand environmental temperatures up to 550°F (300°C). However, the user must remember this

is an electronic instrument and if it is left on a hot surface and the internal temperature is allowed to

exceed 160°F (70°C), the instrument may be permanently damaged.

The specifications on the MultiCorr MKII are described in APPENDIX A "MultiCorr MKII

Specifications".

3.2 Packing

The instrument comes complete with a battery charger, PC data transmission cable, Corrlist

software and a users manual. All of the components are packed in a plastic transportation case filled

with shock absorbing foam.

The plastic case is meant for shipment and storage only, and is not intended for use in a

hazardous area.

3.3 Initial Inspection

The instrument was carefully inspected both mechanically and electronically prior to shipment. It

should be free of physical damage upon receipt. To confirm this, the instrument should be inspected

for any damage that may have occurred during shipment. If any damage is observed please contact

CorrOcean immediately.

3.4 Storage

The instrument may be stored or shipped in environments within the following limits:

Temperature: -5°F to 160°F (-20°C to 70°C)

Humidity: Up to 95%

The instrument must be protected from extreme temperatures which may cause condensation to

form within the instrument case.

It is recommended that the instrument is stored in a dry, cool place (not colder than -5°F (-20°C)) to

minimize battery discharge. To prevent loss of stored data and keep the internal clock running,

recharging should be carried out at least once every 3 months. This recharging should be more often

if the unit is stored at temperatures beyond 85°F (30°C) or if the battery is old.

MultiCorr MKII - User Manual Page: 10

3.5 Charging

Charging time for empty batteries is approximately 12 hours. The instrument may also be operated

during charging.

Charging should only take place in nonhazardous areas.

LOW BATT is displayed on the instrument's status line when the battery charge drops below a

certain limit. The batteries should be recharged as soon as possible after this. If operation

continues, the power will automatically be switched off when the voltage drops below the secure

operation limit. The automatic switch off function is to insure that there is sufficient battery charge

to save stored data. If the instrument has automatically switched itself off under these conditions,

it will not be possible to make measurements until it has been recharged.

NiCd batteries can occasionally develop a "memory" which limits the available user time. If this

occurs deplete the battery through use and then recharge. This process of draining the battery and

recharging may have to be repeated.

3.6 NiCd Batteries

The MultiCorr MKII NiCd batteries have a design life of 3 to 5 years depending on the use and care.

The battery package was made especially for the MultiCorr MKII instrument and are designed not

only for a specific power usage but also for use in a hazardous environment. Changing the battery

should only be conducted by personnel authorized by CorrOcean, to insure that the hazardous area

requirements are maintained.

Warning: NiCd batteries slowly loose their charge even when not in use. For this reason it is

important to charge the batteries at least every 3 months, even if the MultiCorr MKII is not

being utilized.

If the NiCd batteries are not recharged when the LOW BATT Warning appears it is possible that

stored data may be lost if the battery charge level drains below the minimum level

necessary to maintain the MultiCorr MKII memory.

The battery voltage can be seen by selecting STATUS in the system or acq. setup menues.

Both the positive and the negative battery should be at more than 6.25 V when they are charged.

The voltages are however depending on the temperature.

3.7 Connecting to a Personal Computer

The battery charging cable also contains a cable branch for connecting it to a PC RS-232 port. The

MultiCorr MKII may be connected to a PC for data transfer whether or not the battery charger is

connected to an outlet. It is recommended that the charger be connected when data transmission is

being accomplished, but this is not required.

The standard connector on the PC Data Cable is a 25 pin, female connector. Some computer ports

may require the use of a 9 pin female connector, in which case an adapter may be utilized.

Connection to a PC should only take place in nonhazardous areas.

MultiCorr MKII - User Manual Page: 11

3.8 Connecting to a Probe

The MultiCorr MKII is connected to the probe using a flexible retractable probe cable. The probe

cable and connector assembly will be different for the different probe types, and may also be

different for probes from different manufacturers. Probe cables can be supplied by CorrOcean

according to user's specifications. For most commercial corrosion probes, probe cables can be

supplied on short notice. Please contact CorrOcean for more information.

The probe cable has an 11 pin male Fisher connector on the instrument side. There is a white

orientation dot on the Fisher connector that should be visible on the top of the connector when

inserting the cable into the MultiCorr MKII. Always insert and remove the cable by grasping the

connector housing and never pull directly on the cable itself.

The internal wiring of probe cables may be different even when the connector appears to fit the

probe. Make sure that both the probe and cable are compatible for both probe type (e.g. ER, LPR)

and manufacturer.

NOTE:

The instrument housing is electrically conductive. When measuring on LPR and galvanic probes,

the instrument must be held in the hand, or otherwise electrically isolated from ground.

4 MULTICORR MKII INSTRUMENT

4.1 General

The user interface of MultiCorr MKII is implemented with an efficient and easy to learn on screen

menu system. In this manual the definition of a menu is a list of functions which can be selected

with a single numerical key entry. Throughout this manual the keyboard entries are enclosed in

brackets [ ] to distinguish them from other numerical listings. The definition of a window is a

display screen with specified contents. Probe information may also be edited or new information

may be added utilizing CorrOcean's CorrTag Software which is described later in this manual.

Since the MultiCorr MKII can store hundreds of different probes in its memory the operator will

learn how to select a specific probe so that readings are calculated and stored for that specific probe.

In this manual the probe which is ready to accept and store readings at any given time is referred to

as the Active Probe.

4.2 Entry Keys

The key board on the MultiCorr MKII is generally self descriptive but it is helpful to understand the

use of these keys as they are used the MultiCorr MKII.

Key Use Description

[On/Off] On or Off Use to turn the MultiCorr MKII screen on or off. The MultiCorr

MKII has an internal battery saver which will turn off the instrument if no key is pressed

within 2 minutes of the last key entry.

[Del] Delete This key is used to delete the last erroneous character entered.

You may also use the left arrow key to make a deletion.

[Exit] Exit The [Exit] key is used to leave a menu or a window. Terminating

data entry with the [Exit] key leaves the previous value unchanged.

[Ent] Enter When entering parameters such as probe numbers or the surface

area of an LPR Probe electrode, the input must be terminated with the [Ent] key. The

input value will not be accepted until the entered value is within legal limits. When an

illegal entry is made, the display cursor will return to the first position in the input field and

a new value may be entered.

MultiCorr MKII - User Manual Page: 13

Arrows Up/Down Once probe parameters have been entered into the unit the operator can

display the next probe in sequence by pressing the down arrow or returning to a prior probe

with the up arrow.

When the menu is set to display data the operator can move through the reading summary using the

Up and Down arrows.

These arrows are also utilized when selecting the alphanumeric tag numbers. This use is described

more fully later in the manual.

Arrows Left/Right The left arrow may be used to delete an erroneous character entry. These

arrows are also utilized when selecting the alphanumeric tag numbers. This use is

described more fully later in the manual.

4.3 Data Screen

The MultiCorr MKII uses a Liquid Crystal Display (LCD) screen. As a battery saving feature the

screen will automatically go blank if no key has been pressed during any two (2) minute interval.

The screen will also go blank during the periods between automatic readings.

The LCD display utilizes a standard pattern for the display of information.

Line Location Description

First Line Provides the name of the menu. This corresponds to the previous

selection.

Second Line This is a warning information line. When the battery is low a

"LOW BATT" warning will appear. When the instrument is set to automatically take

readings an "AUTO-ON" Warning will appear. Additionally, if the MultiCorr MKII

memory is full a "MEMORY FULL" Warning is displayed.

Lines 3-8 Menu selection alternatives are listed when a menu is displayed.

When the unit is in an operational mode, the last two lines (7-8) display the Active Probe

in memory. Both the probe number and tag number are displayed.

Line 3-8 is also used to display any electrical measuring errors which may be detected by the

MultiCorr MKII. The meaning of these error messages is provided in APPENDIX G -

MultiCorr MKII Error messages.

MultiCorr MKII - User Manual Page: 14

4.4 Probe Identification System - Probes Measured by MultiCorr MKII

The MultiCorr MKII uses a standard method to identify each probe so that the user can readily

identify the probe which is being interrogated. It is important for the user to understand this

identification system prior to reading the manual. The following identification labels have a specific

meaning that is described below.

Probe No Each probe is assigned a unique number that includes both the type of Probe (e.g.

ER, LPR, Galvanic) and a number from 0 to 99. For instance ER 23, LPR 99 or Glv 0.

All ER Probe Numbers will start with "ER" and all LPR Probe Numbers will start with "LPR".

The MultiCorr MKII will distinguish between probes of the same type by the number

following the probe type designation. A total number of 200 different probes may be

defined.

Probe Numbers must be assigned before the MultiCorr MKII will take a reading.

Tag No The Tag Number allows the user to assign a name to each probe that can assist in

identifying the probe. The Tag Number may be up to 10 alphanumeric characters in length.

For instance, the user could tag probe ER 12 with the additional identification of "Riser

A67". When this probe is selected the MultiCorr MKII screen would display the following

as the Active Probe.

Probe: ER 12

Tag No: Riser A67

Tag Numbers are not required to be entered before the MultiCorr MKII takes a reading.

However, it is recommended that Tag Numbers are assigned.

4.5 Probe Identification System - Probes measured by MultiLog

The probes measured by MultiLog are identified by tag no. etc. as defined in the MultiCom

software (it is referred to document 93-3-340 for description of the probe identification system).

However, to reduce complexity and data amount to be transferred, tag numbers etc. are not given in

the probe identification in the MultiLog stations and Terminal. Identification of the probes are

given by MultiLog station no, probe type and number. Probe number starts at 1 for each probe type

for each logger.

When MultiLog data are stored in the MultiCorr MKII memory, "tag number" will be

automatically generated. This number is used only for display of probe data and is not transmitted

when data are sent to PC. However, these tag numbers will be part of the total capacity of 200 tag

numbers, and are cleared by reset of the MultiCorr MKII only (please see section 11.3 for reset

instructions).

MultiCorr MKII - User Manual Page: 15

4.6 Probe Identification System - Probes Measured by SandLog

The probes measured by SandLog are identified by the SandLog address and probe number. A

SandLog is measuring one or two sand probes. A sand probe may have 2, 3 or 4 measuring

elements, and each element is displayed individually. SandLog address and probe number must be

defined before measurements are initiated, please see section 16.2.3 for logger setup. Also see

figure 32 for data display in SandLog.

The corresponding sand probe identification is found when data is transferred to the MultiCorr

MKII. Section 16.3.3 describes display of the stored data, an example is shown in figure 37.

For complete sand monitoring system setup, it is referred to "SandRater Sand Monitoring Program

Operating Manual".

MultiCorr MKII - User Manual Page: 16

5 MENU DESCRIPTION

5.1 The Main Menu

The MultiCorr MKII Main Menu is displayed when the meter is turned on. This menu allows the

user to select two operating modes which are defined as the "Operator Mode" and the

"Advanced Mode".

Operator Mode This is a limited use mode designed to allow only field measurements and

storage. This limited operational mode permits the user to quickly take readings without

the need to utilize the expanded menu selection.

Advanced Mode This menu mode allows the corrosion specialist to set probe parameters,

take automatic readings, set engineering units, transmit data to a PC and perform a wide

variety of specialized operations. Some areas of this menu are protected by a pass code to

insure that inadvertent changes are not made to the system. Field measurements may also

be taken using the mode.

Terminal Mode This menu mode allows setup of CorrOcean MultiLog and/or SandLog

stations, check of data and data retrieval from MultiLog/SandLog and data transfer to

relevant PC software. Some areas of this menu are protected by a pass code to insure that

inadvertent changes are not made to the system.

Shown in Figure 1 is the Main Menu of the MultiCorr MKII. To enter either the

Operator Mode or the Advanced Mode the user simply presses the corre-

sponding selection number located in front of the desired selection. The

MultiCorr MKII will immediately move to the first menu level for that

operating mode.

Figure 1 shows the menu with five (5) types of probe functions and terminal

function installed. Only the functions which are actually installed in the user's

MultiCorr MKII will be displayed.

5.2 Operator Mode

There are only 2 possible selections in this mode. The user can either decide to

take a measurement on the Active Probe or change the Active Probe prior to

making a measurement.

The details on how to install probe information, take measurements and store

the results are provided later in this manual.

Shown in Figure 2 is the Operator Mode Main Menu Window. Details on

making measurements are provided in Section 8.0.

5.3 Advanced Mode

The Advanced Mode allows the user to make measurements in the same

manner as the Operator Mode and also allows the use of the advanced

capabilities in the MultiCorr MKII. The most sensitive functions in the

Advanced Mode are protected with a pass code to prevent data loss or

corruption caused by unauthorized operators.

Shown in Figure 3 is the Advanced Mode Main Menu Window.

There are six (6) general capabilities that can be accessed through the use of the

Advanced Mode. The use of these capabilities are described in more detail later

in this manual. For now it is only important to understand the general

capabilities of the MultiCorr MKII and how these are arranged in the menu

structure.

1. Acquisition Setup This menu route allows the user to enter the various parameters for each

type of probe, enter the tag identification and establish data reading variables such as the

type of engineering units.

2. Measure The user can take field measurements exactly the same way as it is accom-

plished in the Operator Mode.

3. Show Data The user can view all the stored readings for any probe including raw data,

calculated results and corrosion rates.

4. System Setup This menu route allows the user to set the date and time, clear the memory

of readings, clear the unit of probe parameters, change the pass code and also check the

remaining memory.

5. Transmit This feature allows the stored data to be transferred to a computer.

6. Automatic THIS IS AN OPTIONAL FUNCTION THAT MAY NOT APPEAR ON

ALL UNITS. It allows the user to automatically take and store readings at regular intervals.

This function may be added to any MultiCorr MKII.

5.4 Terminal mode

The choice of terminal mode allows user to use the MultiCorr MKII as a terminal for MultiLog

and/or SandLog stations (depending on which functions installed).

If both terminal functions are installed the choice of terminal mode will bring you into a submenu

where you can choose between SandLog and MultiLog terminal. When used as a Sand Terminal

you cannot operate MultiLog stations and vice versa.

If only one terminal function is installed the above mentioned submenu is skipped, and you are

brought directly into the installed terminal menu.

5.5 Menu Paths

As menu selections are made, the MultiCorr MKII will move to the next appropriate menu. This

means that if the MultiCorr MKII needs additional information (For instance, probe parameters) it

will automatically move to the appropriate menu. When the unit has the necessary information to

proceed with an entry it will skip unnecessary menus. This feature saves the user time and

minimizes confusion.

There are some general rules which will assist your understanding of this manual and which are

applicable to all menus.

1. Throughout this manual the keyboard entries are enclosed in brackets [ ] to distinguish

them from other numerical information listings.

2. The Enter Key [Ent] is used to confirm your entry and to move to the next screen.

3. The Exit Key [Exit] is used to leave the entries unchanged and moves you forward in the

menu path.

MultiCorr MKII - User Manual Page: 19

6 PROBE IDENTIFICATION AND METER SETUP

There are general procedures that apply to all probes and these procedures are discussed in this

section. Additionally, the user will learn how to check the operational status of the MultiCorr MKII

and select the type of engineering units which are to be used for the probe readings.

The intent of this section of the manual is only to familiarize the user with general procedures for

identifying and labeling all types of probes. Section 7 takes the operator on a step by step procedure

for entering the parameters for each specific type of probe.

Before taking any measurements the user must assign a unique number to each probe. This number

will define the type of probe (For instance ER or LPR) and allow the MultiCorr MKII to know

where the readings will be stored. At the same time that probe number is assigned you may also

assign a location name, called a Tag Number, to assist you in recognizing the probe you are

measuring. Note that if a Tag Number is not assigned, it is possible to enter the Operator Mode

and change the probe parameters without entering the Pass Code. To protect the probe parameter

setup, a Tag Number must be assigned for the probe.

All of the steps necessary to complete each operation are given along with the keys that need to be

pressed and the results that will be obtained.

6.1 Selecting Probe Type and Assigning a Probe Number

This procedure allows the user to assign a Probe Number without also assigning an identifying Tag

Number.

Step Key Description of Action

------------------------------------------------

1 [On/Off] Turn on MultiCorr MKII

2 [2] Go to Advanced Mode

3 [1] Go to Acquisition Set Up

4 [1] To Edit Probe

5 [Pass Code number] Enter your personal passcode

6 [Ent] Enter pass code and move to next menu

7 [1] To select a Probe Type

8 [1] through [5] Select the type of probe which will be assigned a number

NOTE:

Since every MultiCorr MKII is configured for each user, the meter you are using may not have 5

options from which to select. For your general information the five (5) possible key selections and

the respective probe functions are as follows:

[1] ER [4] Analog

[2] LPR [5] Polarization types

[3] Galvanic

In addition, the two teminal modes, MultiLog and SandLog, are available functions.

9 [Ent] To move to Next Menu Screen

10 Enter Any No. 0 - 99 The user can assign any number from 0 through 99. The numbers

do not have to be consecutive. It is often helpful to assign the numbers in the same

sequence that the operator encounters the probes while taking field readings. HINT: If

additional probes will be added to the reading circuit, skip some numbers so consecutive

number spaces will be available at a future date.

11 [Ent] Enters the number you selected.

From this point on the entries depend on the type of probe being utilized. Section 7 of this manual

provides details on how to enter the parameters for each type of probe. The same steps as shown

above will be repeated, but the background information will be excluded.

6.2 Installing and Editing Probe Tag Identification

The MultiCorr MKII provides two (2) Methods for installing Tag Numbers and probe parameters.

1. Manual installation through the use of key entries on the MultiCorr MKII.

2. Automated downloading of probe files through the use of CorrTag Software.

6.2.1 Manual Probe and Tag Number Entry Using The MultiCorr MKII

This procedure allows the user to assign a Probe Number and also assign an identifying Tag

Number. Generally, this is a preferred manual procedure to just assigning a probe number as

shown above in Section 6.1. However, to assign a Tag Number using the MultiCorr MKII the user

must know the pass code assigned to that particular MultiCorr MKII.
