3.4 mV Calibration

Use a standard ORP solution of known value for calibration. You need to calibrate

only 1-point.

1. Switch on the meter. Make sure the meter is in mV measurement mode.

2. Press CAL (F2) to go to calibration mode.

3. The meter shows ‘Calibration-Rinse Electrode’ screen [Figure 41 (a)] few

seconds and then shows the mV calibration screen [Figure 45 (a)].

4. The screen shows two readings. The upper display shows the mV reading

of the solution with respect to previous calibration (if any) & lower displays

shows the absolute mV reading of the solution without any calibration

(default reading). Use & keys to adjust the upper display to the mV

value of the solution.

5. Press ENTER key to confirm the entered value.

6. The calibration is completed. The meter shows the calibration report

[(Figure 45-(b)].

7. Press ESC (F4) to go to measurement mode. The meter shows the relative

mV reading of the solution in measurement mode, if offset is not zero.

Note: The meter allows you to adjust the upper display reading up to

±150 mV with respect to the default reading.

Note: If the meter is password protected, you will be prompted to enter a

password. Refer ‘Accessing Calibration mode when password protection

enabled’ in pa
