Calibrating/zeroing the R&S
NRPM3(N) sensor
module
Zeroing removes offset voltages from the analog circuitry of the sensor modules,
so that there are only low powers displayed when there is no power applied. The
zeroing process may take more than 8 seconds to complete.
We recommend that you zero in regular intrervals (at least once a day), if :
●
The temperature has varied by more than 5 K.
●
The sensor module has been replaced.
●
No zeroing was performed in the last 24 hours.
●
Signals of very low power are to be measured, for instance, if the expected
measured value is less than 10 dB above the lower measurement range limit.
Turn off all test signals before zeroing. An active test signal during zeroing
causes an error.
