Measurement 2
This is where the mV signal of the reference buffer solution is automatically measured.
The indication of the measurement voltage makes it easier to estimate the
measurement's duration. If the measured value does not change anymore, it can be
assumed that the measurement will be completed shortly and that the calibration will
continue automatically.
The calibration process can be cancelled through operating ENTER.
Mutual conductance
Once the calibration is completed the calculated mutual conductance of the probe is
displayed.
If the calculated mutual conductance is larger than 61 mV/pH or smaller than 54 mV/pH,
a mutual conductance error occurs. This warning indicates that the measurement with
this electrode is within the threshold range and that a new electrode must be placed as
soon as possible. The calibration values are adopted through operating ENTER, which
also opens the calibration module selection screen.
Plausibility error
The above error message appears if the read measured value and the buffer solution
do not match. After acknowledging the error message the measuring mask is opened
again.
Calibration error
The above error message appears if there is no stable measured value. After
acknowledging the error the measuring mask is opened again.
