Sample record:
Note
If non-ID sensors are used, the sensor type and series number are not
output in the calibration record.
Calibration evaluation
After the calibration, the meter evaluates the current status of the
sensor against the relative slope. The evaluation appears on the
display and in the calibration record. The relative slope has no effect on
the measuring accuracy. Low values indicate that the electrolyte will
soon be depleted and the sensor will have to be regenerated.
Calibration in
water vapor
saturated air
(air calibration vessel)
For this calibration procedure, the Comparison meas. setting must be
set to Off in the measuring menu.
Proceed as follows to calibrate the meter:
Note
The sponge in the air calibration vessel must be moist (not wet). Leave
the sensor in the air calibration vessel for a time long enough to adjust.
