1. Verify that the calibrator is set to 0 V dc in standby. Press R if it is not.
2. Turn on the 80 Series DMM, and set its function switch to q.
3. Connect a set of test leads to the DMM as shown in Figure 4-15.
4. Set the calibrator to 3.5 V dc and press O.
5. The DMM should now display 3.500 ±0.001. If necessary, adjust R21 to obtain the
proper display.
6. Set the DMM function switch to p and set the calibrator output to 3.500 V at
100 Hz.
7. The DMM should display 3.500 ±0.002. If necessary, adjust R34 to obtain the proper
display.
8. Change the calibrator output to 10 kHz.
9. The DMM should display 3.500 ±0.004. If necessary, adjust C2 to obtain the proper
display.
10. Change the calibrator output to 35.00 V at 10 kHz.
11. The DMM should display 35.00 ±0.04. If necessary, adjust C3 to obtain the proper
display.
4-58. Testing a Model 41 Power Harmonics Analyzer
The Model 41 Power Harmonics Analyzer, hereafter referred to as the Tester, requires
two voltages at varying phase relationships to test the functionality of the Power and
Harmonics features. The procedure for testing these two functions of the Tester are
included here to demonstrate the operation of the dual voltage function of the Fluke
5500A.
Note
These procedures are included here as an example. The Model 41 Service
Manual contains the complete authoritative testing and calibration
procedures.
4-59. Testing Watts, VA, VAR Performance
Perform the following procedure to test the Watts, VA, and VAR functions of the Tester.
Refer to Table 4-4.
Warning
Ensure that the calibrator is in standby mode before making
any connection between the calibrator and Tester. Dangerous
voltages may be present on the leads and connectors.
