Monitoring internal temperature
You can monitor the temperature difference between the actual internal temperature and the
temperature when auto calibration ran through the panel or by using remote commands. With remote
commands, you can also check the present internal temperature and the internal temperature when
auto calibration was last run. Temperature is returned in Celsius (°C).
The internal temperature is not updated on the Calibration screen until the warmup period is
complete. The remote commands always return the present temperature.
From the front panel:
1. Press the MENU key.
2. Under System, select Calibration.
3. The Temperature Difference is displayed.
Using SCPI commands:
For the present internal temperature, send:
:SYSTem:TEMPerature:INTernal?
For the temperature difference, send:
:ACAL:LASTrun:TEMPerature:DIFFerence?
For the temperature when auto calibration was last run, send:
:ACAL:LASTrun:TEMPerature:INTernal?
Using TSP commands:
For the present internal temperature, send:
print(localnode.internaltemp)
For the temperature difference, send:
print(acal.lastrun.tempdiff)
For the temperature when auto calibration was last run, send:
print(acal.lastrun.internaltemp)
