Note

When switching the range calibrator to STANDBY, allow enough

 

 

time for the range calibrator to settle to its zero value before

 

 

attempting to zero the power meter. This settling would appear on

 

the power meter display as downward drift. When the drift has

 

 

reached minimum, (typically less than 60 seconds), the range

 

 

calibrator is settled.
