The probe can measure the approximate temperature of the CARBOCAP® sensor for compensation, or use a fixed setpoint. Unless a dedicated temperature measurement is available and can be regularly updated to the probe, it is strongly recommended to use the probe's internal temperature compensation to ensure real-time accurate measurements. If the measurement is made in a constant temperature, the constant temperature can be set as the compensation value (fixed setpoint option).

If temperature compensation is turned off, the probe uses the default value of +25 °C (+77 °F).

When the probe is installed through a flange and part of the probe and the cable is left outside the measuring environment, it is possible that temperature conduction from the probe body and cable outside the measurement environment affects the temperature compensation and decreases measurement accuracy.
