Conductivity Calibration & Measurement

The screen will display the calibration type briefly and the 
will start blinking until the reading stabilizes.

1. Rinse the conductivity
electrode with clean
water and blot using
lint-free tissue to
remove excess water.

2. Immerse the conductivity electrode in
standard solution.

3. Press CAL button on the meter to switch
to calibration mode.

4. Press ENT button to conrm the conductivity reading. To abort calibration,
press MEAS key.

Perform calibration using a
standard solution that has a
conductivity value close to the
expected sample value.

For multi-point calibration, start
with the lowest conductivity
standard. Move to standards with
increasing conductivity values.

Make sure that the uppermost black ring in
the conductivity electrode body is immersed
in sample and there are no bubbles trapped
within the electrode.

5. Repeat step nos. 1 to 4 to perform calibration with the next standard solution(s).

6. Rinse the conductivity electrode with clean water and blot using lint-free
tissue to remove excess water.

7. Immerse the conductivity electrode in sample.

The meter allows up to 4 points for auto calibration and up to 5 points for manual calibration.
