Product Calibration
Calibration by sampling – for product calibration, the uncompensated conductivity
(μS/cm, 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, the sample temperature must correspond to the
measured process temperature.
During sampling the analyzer 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 constant (the new cell factor for toroidal sensors).
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.
