Conductivity Calibration & Measurement
The set calibration mode is displayed at the bottom of the
screen. The icon on the screen and LED light on the
electrode (if switched on) will blink until the reading is stable.
1. Rinse the conductivity
electrode with clean
water and wipe 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 button.
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 solution. Move to
standard solutions with increasing
conductivity values.
Make sure that the hole at the bottom of
the conductivity electrode is completely
immersed in the sample.
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 wipe using lint-free tissue
to remove excess water.
7. Immerse the conductivity electrode in sample.
The meter allows up to 4 points in auto calibration mode and up to 5 points in manual calibration mode.
