7.Follow the screen prompts: Once the reading is stable, press ENTER. Take the sample and press ENTER. At this point, the analyzer will store the present sensor current and temperature and use those values in the calibration.

Determine the total chlorine concentration in the sample and enter the value in the screen shown at left. See Section 9.3.1 for sampling and testing precautions.

8.If the calibration is successful, the live reading will change to the value entered in step 7 and the display will return to the screen in step 6.

If the sensitivity is too far outside the range of expected values, the calibration error screen shown at left will appear. The analyzer will not update the calibration. For troubleshooting assistance, see Section 11.5.

9. To return to the main display, press MENU then EXIT.

9.4 CALIBRATING ANALOG OUTPUTS

9.4.1 Purpose

Although the analyzer analog outputs are calibrated at the factory, they can be trimmed in the field to match the reading from a standard milliammeter. Both the low (0 or 4 mA) and high (20 mA) outputs can be trimmed.

9.4.2 Procedure

1.Connect a calibrated milliammeter across the output you wish to calibrate. If a load is already connected to the output, disconnect the load. Do not put the milliameter in parallel with the load.

2.Press MENU. The main menu screen appears. The cursor will be on Calibrate. Press ENTER.

3.Choose the output you wish to calibrate.

4 mA Output 1

Cal Meter:

0 4.000 mA

20 mA Output 1

Cal Meter:

2 0.000 mA

4.The analyzer will simulate the low output current. Change the value in the display to match the reading from the milliammeter.

5.The analyzer will simulate the 20 mA output current. Change the value in the display to match the reading from the milliammeter.
