2 point calibration

For the first point, remove the probe from liquid or
unscrew the connector from the probe (2 electrode
probe) in a known concentration solution. The user
enters this solution value when calibrating.

1 point calibration

Immerse the probe in a known concentration solution.
The user enters this solution value when calibrating.
Note :
Warning ! This calibration is only active on the
slope
The first point of the electric calibration and 2 point
calibration enables to
calibration and to measure the cable capacity with a
2 electrode probe.
It is mandatory to realise one of both calibrations
when starting the MONEC D9125 for the first time.
For the second calibration point use a resistance or a
solution with a significant difference from the first point.
