• Manual calibration
1. Clean the conductivity cell with pure water (or
deionized water) and wipe it with filter paper or
tissue paper.
Do not touch the black electrode part.
Refer to the instruction manual of the conductivity
cell for how to clean the conductivity cell.
2. Immerse the conductivity cell in the standard
solution.
Make sure the hole at the upper part of the cell is
immersed.
3. Press the key to enter the calibration mode
when "ACT" icon is displayed on the lower
part of the screen.
Stability judgment starts and the COND icon
blinks. When the measured value stabilizes, the
COND icon changes from the blinking state to the
lit state.
4. Press the keys to enter the electrical conductivity value of the

standard solution used for calibration at the measurement temperature.
5. Press the key or key.
Calibration to the set standard solution value at the measured temperature is
performed. The 1st point calibration ends and the calibration history icon
corresponding to the calibration range lights, indicating that 1st point calibration is
complete.
The display returns to the measurement screen.
For multiple point calibration, repeat the steps 1. to 5.
The calibration points are up to 5 points.
