g
1. Set compensation temperature in the SETUP (see page 44) and set accompanying com-
pensation correction value to
0.0
°C.
2. With a reference instrument, measure the deviation in the stationary state in the selected
compensation temperature.
3. Set the compensation correction value in the SETUP. If the measured reference tempera-
ture 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: The temperature deviation in the chamber load at 35 °C should be corrected.
1. Set the compensation temperature
CAL.2 in the SETUP to 35.0
°C and the accompanying
compensation correction value to
0.0
°C:
h
°C
°C
2. With a calibrated reference instrument and at a set setpoint temperature of 35 °C in nor-
mal operation, an actual temperature of 34.6 °C is measured.
3. Set compensation correction value for
CAL.2
in the SETUP to
- 0.4
°C:
h
°C
°C
4. The reference instrument after the calibration procedure should now display 35 °C.
5. With
CAL.1
, another compensation temperature below
CAL.2
can be programmed in the
same way, and with
CAL.3
, one lying above this.
If all compensation correction values are set to
0.0
°C, the factory calibration settings are
restored.
