Setting:
1. Set the desired compensation temperature in the SETUP (see Chapter 7.2 Basic appliance
settings (Setup) on page 46 ) and set the corresponding compensation correction value to
0.0 °C.
2. With a reference instrument, measure the deviation in the stationary state in the selected
compensation temperature.
3. Setting the compensation correction values in the SETUP. If the measured reference temperature
is too low, the compensation correction value must be set with a negative sign.
4. Perform a control measurement with the reference instrument.
5. Repeat the procedure for the other two balance points if necessary.
Example: Temperature deviation at 30 °C should be corrected.
1. Set compensation temperature CAL.2 in the SETUP to 30.0 °C and set the accompanying
compensation correction value to 0.0 °C:

2. At a set setpoint temperature of 30 °C in normal operation, an actual temperature of 29.6
°C is measured with a calibrated reference instrument.
3. Set the compensation correction value for CAL.2 in the SETUP to – 0.4 °C:
