2-Wire pH or ORP Transmitter

Operating Instructions

1Preface

Thank you for purchasing the Eutech pH or ORP Transmitter.

This manual serves to explain the correct installation and operations of

the XTR Transmitters. Other Transmitters available individually are: pH,

ORP (REDOX), Conductivity, Dissolved Oxygen and Temperature.

•EC-PH-XTR;

•EC-ORP-XTR;

•EC-CON-XTR;

•EC-DO-XTR; and

•EC-TEMP-XTR.

The information presented in this manual is subject to change without

prior notice, as improvements are made to the product. While Eutech will

endeavor to try its best to inform the market, this does not represent a

2Introduction

The Transmitter is used for the continuous measurement of pH, ORP

(REDOX), Conductivity, Dissolved Oxygen or Temperature, in conjunction

with an appropriate sensor. Data output is via 4-20 mA current output.

The Transmitter is housed in a IP65 enclosure, with openings for input

and 4-20mA output.

5Electrical Connections

NOTE: In electrically “noisy” environments, select ‘Symmetrical’ mode of

operation and connect a stainless steel rod (Potential Matching

Pin - PMP) as shown above. Ensure both the PMP and pH or

ORP electrodes are immersed into the solution, even when

performing calibration.

6Before Calibration

Remove cover of Transmitter and ensure that electrode is correctly

connected as above. Connect Amp meter to the 4/20mA output of

Transmitter (Appendix 1).

7pH Transmitter Calibration

1) Calibrate in pH 7.00 buffer first, and then in either pH 4 or pH 10.

2) First, immerse clean pH electrode into a container with fresh pH 7.0

buffer solution;

3) Amp meter should read 12mA; if not, calibration is necessary;

4) Locate “Offset adjustment” trimmer; Using a fine screwdriver,

slowly turn trimmer till Amp meter reads 12mA;

5) For greater accuracy, adjust slope with pH 4 or 10;

6) Rinse probe in de-ionised water and immerse in either pH 4.01 or pH

10.01 buffer solution;

7) In pH 4.01, the output is 8.54mA;

8) In pH 10.01, the output is 15.44mA;

9) Using a fine screwdriver, slowly turn trimmer, marked ‘slope’, till Amp

meter reads correct mA value with respective buffer solutions.

10) Remember to disconnect Amp meter and close cover.

NOTE: For other buffer values, expected current output is based on:

mA = {(16/14) x buffer pH value} + 4mA

8ORP Transmitter Calibration

1) Prepare fresh Standard solutions, such as 255mV, 470mV.

2) Short ORP inputs and observe Amp meter display;

3) Amp meter should read 4mA; if not, calibration is necessary;

4) Locate “Offset adjustment” trimmer; Using a fine screwdriver,

slowly turn trimmer till Amp meter reads 4mA;

5) For greater accuracy, adjust the slope with Standard calibrating

solutions;

6) Rinse probe in de-ionised water and immerse in standard solution;

7) In 255mV solution, the output is 8.08mA;

8) In 470mV solution, the output is 11.52mA;

9) Using a fine screwdriver, slowly turn trimmer, marked ‘slope’, till Amp

meter reads correct mA value with respective Standard solutions.

10) Remember to disconnect Amp meter and close cover.

NOTE: For other Standard values, expected current output is based on:

mA = {(16/1000) x ORP value of Standard solution} + 4mA
