The menu structure for calibration is identical for the individual sensors and appears as follows:
Fig. 25: Menu structure for sensor calibration
If the calibration is successful, the message 'CALIBR. SUCCES.' If the measured values are outside
specific limits, the message 'VALUE OUTSIDE' is displayed and the user is then prompted to
'ACCEPT CALIBRATION' or 'ABORT'. If a sensor cannot be calibrated, it may have to be replaced.
If sensors are calibrated too often, this can have a negative effect on the accuracy. For this reason,
it is possible to reset the sensors to the factory setting. In the sensor calibration menu in question,
there is the item UNCAL. If this is confirmed with YES, the sensor is reset to its original value. The
message 'UNCAL OK' appears on the display.
Calibrating conductivity measurement
For calibrating the conductivity sensor, you can choose from the following output forms: specific
conductivity, conductivity in original form and salinity. One version is enough to calibrate the
conductivity sensor.
Act. value Displays the current measured value of the sensor, the unit corresponds to the
setting made.
Uncal Calibration values are reset to the factory setting when you confirm with YES.
Cal. value For entering the value of the calibration solution used.
Calibrate The calibration is confirmed by selecting ACCEPT.
