5.3 Continuous measurement control (CMC function)
The Continuous Measurement Control (CMC function) facilitates to evaluate
the current measured value instantly and definitely.
After each successful calibration the scale of the pH measuring range is dis-
played in the measured value display. Here you can very clearly see whether
or not the current measured value is in the calibrated part of the measuring
range.
The following information is displayed:
- -30 ... +30 -62 ... -61
or
-56 ... -50
Clean the IDS sensor according to the
sensor operating manual
Error Error
< -30 or
> 30
... -62 or
... -50
Eliminate the error according to chapter

For pH IDS sensors, you can optionally enable a more finely
graded calibration evaluation (QSC) (see section 5.4).
