CALibration<Channel>:ZERO:AUTO <state>
Performs zero calibration.
Turn off all test signals before zeroing. An active test signal during zeroing causes an
error.
While zero calibration is in progress, no queries or other setting commands are
allowed, since the command is synchronous. Any communication attempt can run into
a timeout.
After zero calibration, query the static error queue (SYSTem:SERRor?). The following
responses are possible:
●
0
No error, the zero calibration was successful.
●
-240
Warning, zero calibration failed. See also the example.

9.11 Testing

The selftest allows a test of the internal circuitry of the power sensor.
Do not apply a signal to the sensor while the selftest is running. If the selftest is carried
out with a signal being present, error messages can erroneously be output for the test
steps Offset Voltages and/or Noise Voltages.
