Essential instructions

Read this page before proceeding!

Emerson designs, manufactures, and tests its products to meet many national and international

standards. Because these instruments are sophisticated technical products, you must properly install,

use, and maintain them to ensure they continue to operate within their normal specifications. You

must adhere to the following instructions and integrate them into your safety program when

installing, using, and maintaining Emerson's Rosemount

™

products. Failure to follow the proper

instructions may cause any one of the following situations to occur: loss of life, personal injury,

property damage, damage to this instrument, and warranty invalidation.

• Read all instructions prior to installing, operating, and servicing the product.

• If you do not understand any of the instructions, contact your Emerson representative for

clarification.

• Follow all warnings, cautions, and instructions marked on and supplied with the product.

• Inform and educate your personnel in the proper installation, operation, and maintenance of the

product.

• Install equipment as specified in the installation instructions of the appropriate Quick Start Guide

and per applicable local and national codes. Connect all products to the proper electrical and

pressure sources.

• To ensure proper performance, use qualified personnel to install, operate, update, program, and

maintain the product.

• When replacement parts are required, ensure that qualified people use replacement parts

specified by Emerson. Unauthorized parts and procedures can affect the product's performance,

place the safe operation of your process at risk, and may result in fire, electrical hazards, or

improper operation.

• Ensure that all equipment doors are closed and protective covers are in place, except when

maintenance is being performed by qualified people, to prevent electrical shock and personal

injury.

Note

The information contained in this document is subject to change without notice.

WARNING

Pressure and temperature

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig

and the process temperature is lowered to a safe level.

Do not insert or retract retractable sensors when process pressures are in excess of 64 psig (542

kPa) for option 21 or 35 psig (343 kPa) for option 25.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end

users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your

system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for

all systems used within the facility.

2 Start up and calibrate

2.1 Prepare electrode

Procedure

1. Remove electrode from shipping container.

2. Remove the protective boot covering the electrode bulb.

3. Rinse away salt film with clean water; then shake the electrode so

that the internal solution fills the bulb, thus removing any air trapped

there.

2.2 Calibrate with two point pH buffer solution

Select two stable buffer solutions, preferably pH 4.0 and pH 7.0. You can use

buffers other than pH 4.0 and pH 7.0 as long as the pH values are least two

pH units apart.

Note

A pH 7 buffer solution reads an mV value of approximately zero, and pH

buffers read approximately ±59.1 mV for each pH unit above or below pH 7.

Check the pH buffer manufacturer specifications for milivolt values at

various temperatures, since temperature may affect the actual value of the

pH buffer solution mV/pH value.

Procedure

1. Immerse the sensor in buffer solution.

Make sure the buffer solution contacts the metal housing of the

sensor, which acts as the solution ground contact.

2. Allow sensor to equilibrate to the buffer temperature and wait for the

reading to stabilize.

The transmitter can now acknowledge the value of the buffer.

3. Rinse the buffer solution off of the sensor with distilled or deionized

water.

4. Repeat steps Step 1 through Step 3 using the second buffer solution.

The theoretical slope value, according to the Nernst equation for calculating

pH, is approximately 59.17 mV/pH. Over time the sensor will age, both in

the process and in storage, and this will result in reduced slope values. To

ensure accurate readings, Emerson recommends replacing the electrode

when the slope value falls below 47 to 49 mV/pH.

2.3

Standardize pH sensor

For maximum accuracy, you can standardize the sensor in-line or with a

process grab sample after performing a buffer calibration and conditioning

Quick Start Guide November 2020

16 Emerson.com/Rosemount

the sensor to the process. Standardization accounts for the sensor junction

potential and other interferences. Standardization does not change the

sensor's slope, but simply adjusts the transmitter's reading to match that of

a known process pH.
