Figure 31 : Conductivity Calibration Screen
1. The upper display shows the conductivity reading of the solution with
respect to previous calibration (if any) & lower display shows the
conductivity reading of the solution without any calibration. Use & keys
to adjust the upper display of the conductivity value of your custom solution.
2. Press ENTER key to confirm the calibration.
3. Press ESC (F4) to go to measurement mode.
4. For multi point calibration , select multi point in Setup page to calibrate.

2.8 Automatic Calibration (For Conductivity Calibration)
In the Automatic Calibration mode, the meter is capable of accepting either
single-point or up to 4 points for multi-point calibration with a maximum of 1
point per specific measurement range. Select automatic calibration mode in the
Conductivity Setup screen. Press
(F2) to start calibration and the meter displays
