General calibration instructions:
1. Select the required calibration temperature in SETUP and set the corresponding calibration
correction to 0.0°C.
2. Measure the deviation from the selected calibration temperature under steady conditions, using a
reference instrument.
3. Set the calibration correction in SETUP. If the measured reference temperature is too low, the
calibration correction setting has to have a negative sign.
4. Carry out a check measurement using the reference meter.
5. The procedure can be carried out for up to 3 calibration temperatures.
