Returns the onboard temperature of the device, in degrees Celsius, during the oldest successful self-calibration from among the channels in the session.

Syntax

ViStatus _VI_FUNC niDCPower_GetSelfCalLastTemp(ViSession vi, ViReal64 *temperature)

Remarks

For example, if you have a session using channels 1 and 2, and you perform a self-calibration on channel 1 with a device temperature of 25 degrees Celsius at 2:00, and a self-calibration was performed on channel 2 at 27 degrees Celsius at 3:00 on the same day, this function returns 25 for the temperature parameter.

Note

This function is not supported on all devices. Refer to Supported Functions by Device for more information about supported devices.

Note

This function can only be used in a session initialized to a single instrument.
