6.3 Calibration
The following procedures should be performed at routine intervals to ensure that the Power
Analyzer remains within specified limits. In addition, calibration should be performed following
repairs involving accuracy determining components.
Remove the top cover from the unit to gain access to the internal adjustments. The locations of
the adjustments are listed on the circuit board and on drawing number 2105-600 at the back of
this manual. Apply power to the 2100 and test equipment and allow approximately 30 minutes
for stabilization.
Note that the instrument may also be returned to the factory for full calibration traceable to
NIST.
