Test Procedure
NOTE This procedure assumes the use of the recommended equipment model numbers. The
actual step required, therefore, may differ for other model numbers of equipment used.
Step 1. Setup the equipment as shown in Figure 1-2.
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.
