DECOMPRESSION MODEL

The programs within the Pro Plus 2 simulate the absorption of nitrogen into the body by using a mathematical model.

This model is merely a way to apply a limited set of data to a large range of experiences. The Pro Plus 2 dive computer

model is based upon the latest research and experiments in decompression theory. Still, using the Pro Plus 2, just

as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decom-

pression sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day.

No machine can predict how your body will react to a particular dive profile.

INTRODUCTION

Welcome to Oceanic and thank you for choosing the Pro Plus 2 !

It is extremely important that you read this Operating Manual in sequence and under-

stand it completely before attempting to use the Pro Plus 2.

It is equally important that you read the Oceanic Dive Computer Safety and Reference

Manual (Doc. No. 12-2262) provided with your Pro Plus 2. It contains information that

you must become familiar with prior to diving with your Pro Plus 2.

Remember that technology is no substitute for common sense, and a dive computer only

provides the person using it with data, not the knowledge to use it.

INTERACTIVE CONTROL CONSOLE

The Interactive Control Console consists of two Control Buttons

that allow you to select display options and access specific

information when you want to see it. They are also used to

enter Settings, activate the Backlight, and acknowledge the

Audible Alarm.

The Left button is referred to as Advance (Fig. 1a) and the

Right button as Select (Fig. 1b).

BAR GRAPHS

Tissue Loading Bar Graph (TLBG)

The Tissue Loading Bar Graph (Fig. 2a) represents tissue

loading of nitrogen, showing your relative no decompression

or decompression status. As your depth and elapsed dive

time increase, segments will add to the Graph, and as you

ascend to shallower depths, the Bar Graph will begin to

recede, indicating that additional no decompression time is

allowed for multilevel diving.

The Tissue Loading Bar Graph monitors 12 different nitrogen

compartments simultaneously and displays the one that is in

control of your dive. It is divided into a green No Decom-

pression (normal) zone, a yellow Caution zone (also No

Decompression), and a red Decompression (danger) zone.

While you cannot provide a guarantee against the occur-

rence of decompression sickness, you may choose your own

personal zone of caution based upon age, physique, exces-

sive weight, etc., to reduce the statistical risk.

NOTE: Displays associated with oxygen and the O2

Bar Graph will only appear if FO2 has been set at a

value other than 'Air' (e.g., a numerical value).

Oxygen Accumulation Bar Graph (O2BG)

The O2 Bar Graph (Fig. 3a) represents oxygen loading, showing the maximum of either

per dive accumulated oxygen, or 24 hour period accumulated oxygen.

As your oxygen exposure (accumulation) increases during the dive, segments will add to

the Bar Graph, and as loading decreases, it will begin to recede, indicating that addi-

tional exposure is allowed for that dive and 24 hour period.

Variable Ascent Rate Indicator (VARI)

The Variable Ascent Rate Indicator (Fig. 3b) provides a visual representation of ascent

speed (i.e., an ascent speedometer). Green is a 'normal' rate, yellow a 'caution' rate,

and red is 'Too Fast'. The segments of the VARI represent two sets of speeds which

change at a reference depth of 60 feet (18 meters). Refer to the chart (Fig. 4) for seg-

ment values.

Fig. 3 - O2BG and VARI

WARNING: At depths greater than 60 feet (18

meters), ascent rates should not exceed 60 fpm (18

mpm). At depths of 60 feet (18 meters) and shallower,

ascent rates should not exceed 30 fpm (9 mpm).

Air Time Remaining Bar Graph (ATRBG)

The Air Time Remaining Bar Graph (Fig. 5a) provides a

graphic representation of the time that you can remain at your

present depth and then, following a safe ascent, surface with a

predetermined reserve of breathing gas.

This calculation and display is based on your Breathing Gas

Consumption Rate that is continuously monitored by the Pro

Plus 2, and it takes into account the breathing gas required for

a safe ascent including any required decompression stops.

The green, yellow, and red zones adjacent to the bar graph

enable you to quickly focus on remaining breathing gas times of 60 minutes and less,

based on your pre selected End Pressure Alarm Set Point (described later). The bar

graph is more precise as time decreases toward the red zone.

DIVE TIME REMAINING

The Pro Plus 2 constantly monitors three critical pieces of information; no decompression

status, oxygen accumulation, and breathing gas consumption rate. Refer to the Oceanic

Dive Computer Safety and Reference Manual which describes Dive Time Remaining

which is a display that indicates the time that is more critical for you at that particular

moment (i.e.; whichever time is the least amount available of the three).

Displayed will be either Time Remaining before reaching the No Decompression limit

(Fig. 5b), or Time Remaining before reaching the limit for Oxygen Accumulation, or Time

Remaining before reaching the End Pressure Alarm set point.

ALPHA / NUMERIC DISPLAYS

Cylinder Pressure Display

Cylinder Pressure (Fig 6a) is displayed any time the Pro Plus

2 is connected to a pressurized cylinder and in an active

operating mode.

Values of pressure are displayed numerically from 10 PSI (.5

BAR) up to 5000 PSI (352 BAR) in increments of 10 PSI (.5

BAR).

Depth Displays

During a dive, the Current Depth display (Fig. 6b), indi-

cates depths from 0 to 330 feet (99.9 meters) in 1 foot (.1

meter) increments.

By pressing the Left (Advance) button, the Maximum

Depth reached during that dive will be displayed in the

center/left portion of the display (Fig. 6c).

During a Decompression Dive, the required Ceiling Stop

Depth is displayed in the center of the screen. Maximum

Depth can be viewed by pressing the Left (Advance) button.

Time and Date Displays

Time displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16

minutes, not 116 minutes!). The colon that separates hours and minutes blinks once per

second when the display is indicating real time (e.g., Elapsed Dive Time), and is solid

(non-blinking) when times are calculated projections (e.g., Time to Fly).

The Main Time display is located in the lower/middle portion of the display (Fig. 7a)

and a second time display (Fig. 7b) is located in the center/right. Both displays are

identified by clock icons.

• Time of Day can be set for 12 hour format (Am/Pm) or 24 hour format.

Date is displayed in the center/left portion of the screen only

to identify dive data while it is viewed in the Log Mode (see

page 70). When Units of Measure are set for 'Imperial', the

Month appears to the left of Day. When set for Metric, the

Month appears to the right of Day.

Temperature Display

Ambient Temperature is displayed in the center/left

portion of the screen (Fig. 7c) while in the Surface Mode and

Log Mode, and can be viewed as part of an Alternate Display

when the Left (Advance) button is pressed while in a dive

mode. If the Temperature exceeds a value of '99', two dashes

( - - ) will be displayed on the screen until the unit's tempera-

ture decreases to '99'.

Displays

NOTE: Each numeric and graphic display represents a unique piece of informa-

tion. It is imperative that you understand the formats, ranges, and values of the

information represented to avoid any possible misunderstanding that could result

in error. The Informational Displays are described in detail as the various operat-

ing modes they appear in are presented throughout this manual.

AUDIBLE ALARM

LED Warning Light

A red LED Warning Light will light and a Speaker icon will appear when the Audible

Alarm emits a tone. They will turn off when the Alarm is acknowledged, and will not

activate if the Audible is Set OFF (a user setting).

When warning situations activate the Alarm, the unit will emit a continuous tone for 10

seconds, or until the situation is corrected, or it is acknowledged by the user pressing the

Left (Advance) button for 2 seconds. If acknowledged by the user and the situation

corrected, the Alarm will sound again upon reentry into the warning situation, or entry

into another type of warning situation.

A single short beep (which cannot be disabled) is emitted for the following -

• After the Diagnostic countdown, if everything is okay.

• If the unit automatically returns to Surface Mode from Simulator Mode.

• Upon completion of a Hot Swap battery change with calculations saved.

• Change from Delayed to Full Violation 5 minutes after the dive.

Situations that will sound the Alarm, if it is turned ON (a user setting), include -

• Entry into Decompression Mode.

• Air Time Remaining Bar Graph Alarm (a user setting).

• Air Time Remaining = 5 minutes.

• Air Time Remaining = 0 minutes.

• Turn Pressure Alarm (a user setting).

• End Pressure Alarm (a user setting).

• PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA.

• Descent deeper than the Max Depth Alarm (a user setting).

• Tissue Loading Bar Graph Alarm (a user setting).

• Dive Time Remaining Alarm (a use setting).

• Elapsed Dive Time Alarm (a use setting).

• O2 Accumulation => allowable per dive limit, or limit for a 24 hour period.

• Ascending above a required Decompression ceiling stop depth for less than 5 minutes

(referred to as a Conditional Violation).

• Ascent rate exceeds 60 feet/minute (18 meters per minute) if greater than 60 feet (18

meters), or 30 feet/minute (9 meters/minute) at 60 feet (18 meters) and shallower.

During the following situations, the 10 second continuous tone will be followed by a 5

second steady beep that will not turn off when acknowledged, even if it was user Set

OFF -

• Ascending above a required Decompression ceiling stop depth for more than 5

minutes (referred to as a Delayed Violation).

• Decompression requires a ceiling stop depth of 70 feet/21 meters or deeper.

• Being on the surface for 5 minutes after a Conditional Violation (Permanent Violation).

SMARTGLO

BACKLIGHT

To activate the Backlight - press the Right (Select) button.

• The Smart Glo

feature senses the intensity of natural

light present. If a low level of light is present, the Back-

light will activate and illuminate the display for button

depression time plus the user set additional Duration time

(3 or 7 seconds).

• Press the button again to activate as desired.

NOTE: Extensive use of the Backlight reduces

estimated Battery life. Also, the Backlight does not

operate during a Low Battery Condition or when

downloading data to a PC.

POWER SUPPLY

The Pro Plus 2 utilizes one (1) 3 volt, CR2 Lithium Battery that

should provide from 50 dive hours of operation, if you

conduct 1 - one hour dive each time the unit is activated, to

over 150 dive hours of operation, if you conduct 3 or more

one dives each time the unit is activated.

Battery Indicator

A Battery Indicator (Fig. 8a) provides an indication of Battery

condition. The Battery Indicator will be displayed during

Surface Mode. It will not be displayed during Dive Mode(s).

PSI

ATR

Fig. 9 - Low Battery Condition

Low Battery Condition

• Voltage level is checked upon activation and every 10

minutes during operation.

• When 75 % of the Rated Power has been consumed,

only the lower bar of the Indicator will be displayed and

the full icon will flash (Fig. 9) once per second as a

warning that the Battery is to be replaced prior to con-

ducting any further dives.

• Upon decreasing to a voltage level that will no longer

sustain proper operation, the Battery Indicator will flash 5

times followed by shutdown of the unit.

• If a Low Battery Condition exists when the unit is manu-

ally activated (by pressing the button), the graphic bAT

and the Battery Indicator will appear flashing for 5

seconds followed by shutdown of the unit.

• If the button is not pressed to activate the unit prior to a

dive (e.g., the unit activated automatically by immersion

in water), and a Low Battery Condition exists, the Battery

Indicator will appear flashing as a warning upon descent

past 4 feet (1.2 meters). No other information will be

displayed and the unit will not enter Dive Mode.

• If the unit did not display a Low Battery Condition prior to

entering the Dive Mode, and a Low Battery Condition

occurs during the dive, there will be sufficient Battery

power to maintain unit operation for the remainder of

that dive. The Battery Indicator will appear after the dive

upon entry into Surface Mode.

• When the Battery is removed, settings and calculations

for repetitive dives will be retained, if a new battery can

be inserted within 8 seconds. Otherwise the calculations

will reset to zero and settings must be reset.

FO2 MODE

After Activation, the Pro Plus 2 will operate as an Air com-

puter without displaying information associated with oxygen

calculations, unless it is set for a percentage of oxygen (FO2)

other than Air (a numerical value between 21 and 50 %).

When set with an FO2 value of 'Air' (Fig. 10), the Pro

Plus 2 will perform calculations the same as if FO2 were set

for 21% oxygen, internally accounting for oxygen loading for

any subsequent Nitrox dives. However, oxygen related

displays, warnings, and the O2 Bar Graph will not appear

on the display for that dive, or subsequent dives, unless FO2

is set for a numerical value (21 - 50).

Fig. 10 - FO2 set for AIR

ATR

Fig. 11 - FO2 set for 21%

Once a dive is made with the unit set as a Nitrox Computer

(FO2 set for a numerical value), it cannot be programmed to

operate as an Air Computer until 24 hours after the last dive.

'Air' will not be displayed as an option in the FO2 Mode.

However, you can set FO2 for 21% for use with Air.

When FO2 is set at a value of 21% (Fig. 11), the unit will

remain set at 21% for subsequent nitrox dives until FO2 is

set to a higher value, or until it automatically turns off and is

reactivated.

FO2 50% Default

If the Default function is set to ON (Fig. 12) and FO2

is set to a value 'greater than 21%', the FO2 set point value

will automatically revert to 50% 10 minutes after that dive.

The Maximum Depth that can be achieved with a PO2 of

1.60 ATA will also be displayed.

• FO2 must therefore be reset for each repetitive nitrox

dive, or the value will automatically 'default' to 50(%)

and the dives will be calculated based on 50% O2 (50%

nitrogen) for oxygen calculations and 21% O2 (79%

nitrogen) for nitrogen calculations.

Fig. 12 - FO2 Default ON

MAX

ATR

Fig. 13 - FO2 Default OFF

If the Default function is set to OFF (Fig. 13), the FO2

value for repetitive dives remains the same as previously set

until the set point is manually changed.

WARNING: When the unit shuts off, the FO2 set point

will default to AIR regardless if the 50% Default is set

ON or OFF. Always set, or verify, the FO2 set point

prior to each nitrox dive.

Setting FO2 for a nitrox dive is described on page 25.
