Via (INFO) or (CAL) you select the position to change.
Via (CONF +1) or (LOG -1) you change the position.
(ON/OFF) confirms and saves your setting.
(MEAS) terminates the entry dialog without transferring the value.
10.6.2.2 Temperature offset
Under menu item "Temp.Offs." you can enter an offset for the temperature value.
> Select "Temp.Offs.".
An input dialog allows you to set up the offset. This value can be positive or negative.
Via (CONF +1) or (LOG -1) you selected the desired setting.
(ON/OFF) confirms and saves your setting.
(MEAS) terminates the entry dialog without transferring the value.
10.6.2.3 One point calibration
The measuring signal will be calibrated at this one point by means of a defined calibration solution or
with a known nominal value, e.g. via an independent procedure or a lab/field device.
> Sie werden aufgefordert, den Sensor in das Kalibriermedium zu tauchen.
Confirm this dialog with (ON/OFF). The currently measured value is displayed.
If the measured value is in stable condition, reconfirm the dialog box with (ON/OFF).
> You will be prompted to enter a nominal value.
Via (CONF +1) or (LOG -1) you selected the desired setting.
(ON/OFF) confirms and saves your setting.
(MEAS) terminates the entry dialog without transferring the value.
This completes the calibration process. The new calibration value will be saved in the device.
10.6.2.4 Automatic calibration
The automatic calibration of the conductivity sensor is a one point calibration with automatic buffer
detection.
The following conductivity calibrations are archived:
0.01 N KCl:
1.41 mS/cm (25 °C)
0.1 N KCl:
12.9 mS/cm (25 °C)
> You will be prompted to immerse the sensor into the calibration medium.
Confirm this dialog with (ON/OFF). The currently measured values will be displayed.
If the measured values (conductivity + temperature!) are in a stable condition,
reconfirm by pressing (ON/OFF).
This completes the calibration process. The new calibration value will be saved in the device.
If the calibration is faulty, an error message will be displayed (see 10.6.2.5).
10.6.2.5 Calibration error
The limits for all calibration values are saved in the meter. If the entered values are outside these
limits, one of the following error messages will be displayed:
"!Incorrect entry!" or "!Calibration error!".
You may have to repeat the calibration, service the sensor or replace it (wear part!).
