Equipment Used for the Power Meter Accuracy Test
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.
Test Procedure
Step 1. Setup the equipment as shown in Figure 1-1.
a. Connect the DC REFERENCE OUTPUT connector on the rear panel of the
range calibrator to the DVM voltage input.
b. Connect the POWER METER output of the range calibrator to the input of
the power meter being tested.
c. Switch on the power to the power meter, the range calibrator, and the
digital voltmeter.

It is recommended that a copy of the test record on page 36 be made, and
the values be recorded on the copy, thus preserving the original for future
use.
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.
