The ITC4000 controllers offer an offset compensation for temperature sensors. The setting
range is ±10 °C. Use a calibrated thermometer to verify the real sensor temperature. From this,
subtract the temperature displayed by the ITC4000 (take care of the proper signs). Enter the
result as Sensor Offset in the Temperature Sensor Settings Menu. The displayed actual tem-
perature will be shifted by this amount and will give you an improved absolute accuracy.
