Calibration
Product Calibration
(Calibration by sampling)
For product calibration, the uncompensated conductivity (mS/cm,
S/m) is used. 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
portable meter. To ensure an exact calibration, sample temperature
and process temperature should be the same.
During sampling the device saves the currently measured value
and then returns to measuring mode. Then, 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 cell factor.
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.
