Product calibration
Product Calibration (pH)
Calibration by sampling (one-point calibration).
During product calibration the sensor remains in the process.
The measurement process is only interrupted briefly.
Procedure:
1) The sample is measured in the lab or directly on the site using a por-
table meter. To ensure an exact calibration, the sample temperature
should correspond to the measured process temperature.
During sampling the device saves the currently measured value and
then returns to measuring mode. The “calibration“ mode indicator
blinks.
2) In the second step you enter the measured sample value in the
device. From the difference between the stored measured value and
entered sample value, the device calculates the new asymmetry
potential.
If the sample is invalid, you can take over the value stored during
sampling. In that case the old calibration values are stored.
Afterwards, you can start a new product calibration.
