Description of the Test

The power meter accuracy is verified for various power inputs and the actual
readings are recorded in a test record. A range calibrator is used to provide the
reference inputs.
It is recommended that a copy of the test record on
the values be recorded on the copy, thus preserving the original for future
use.
Test Procedure
This procedure assumes the use of the recommended equipment model
numbers. The actual steps required, therefore, may differ for other model
numbers of equipment used.
Step 1. Setup the equipment as shown in
a. Connect the DC REFERENCE OUTPUT connector on the rear panel of the
b. Connect the POWER METER output of the range calibrator to the input of
c. Switch on the power to the power meter, the range calibrator, and the
