3.7 Resistivity Calibration

Use a standard solution of known value for calibration. Use the single-point

standardization option to measure samples that close in value and multi-point

standardization to measure wide range of samples.

1. Switch on the meter. Make sure the meter is in resistivity measurement

mode.

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

3. The meter shows ‘Calibration-Rinse Electrode’ screen [Figure 48-(a)] few

seconds and then shows the cell constant adjustment screen [Figure 52-

(a)].

4. The upper display of the resistivity cell constant screen [Figure 52-(a)]

shows the resistivity cell constant of your solution & lower display shows

the measured value of the solution with adjusted cell constant. Press &

keys to adjust the cell constant for your custom solution in upper display.

5. Press ENTER key to confirm the entered value and to go to resistivity

calibration screen.

6. The screen shows two readings. The upper display shows the resistivity

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

display shows the resistivity reading of the solution without any calibration.

Use & keys to adjust the upper display of the resistivity value of your

custom solution.

7. Press ENTER key to confirm the entered value.

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
