Indicates in degrees Celsius the temperature of the device at the time of the last external calibration. Compare this temperature to the current onboard temperature to determine if you should perform another calibration.

The temperature returned by this property is the calibration temperature as measured by an onboard temperature sensor and may differ from the temperature displayed on a printed calibration certificate. Calibration certificates usually display the ambient temperature rather than the onboard temperature.

Using Traditional NI-DAQ (Legacy) to perform calibration does not update this property. This property is updated only when you use NI-DAQmx to perform calibration.
