11 Calibration
The next target temperature is displayed as blinking.
✱
Warm up the sample medium until is it above the temperature that is
blinking.
✱
Repeat the procedure as often as required, until the device has determined
all 6 temperature coefficients.
The LC display now shows the derived temperature coefficients in %/°C.
✱
To accept the temperature coefficients that have been determined -> press
the
key for at least 3 seconds or
to reject the values -> press the key.
The transmitter is in the calibration menu.
✱
Press the key.
The transmitter is now in the measurement mode, and shows the
compensated conductivity of the reference solution.
During calibration, the rate of change of temperature for the
sample solution must not exceed
10°C/min for the device with exposed temperature sensor, or
1°C/min for the device with an internal temperature sensor.
As soon as one of the target temperatures has been reached, its
display becomes static (no longer blinking).
