Usage
temperature = acal.lastrun.tempdiff
temperature
The internal temperature
Details
The temperature is displayed in Celsius (°C).
The instrument updates the internal temperature value when the instrument refreshes autozero. If
autozero is set to off or if autozero is not available for the selected function (such as capacitance,
continuity, frequency or period), the internal temperature value is not updated.
Example
print(acal.lastrun.tempdiff)
Returns the difference between the temperature of the
instrument when auto calibration was run and the present
internal temperature.
Example output:
4.5678
