How to Calibrate the Meter
Continue with calibration if any range was out of tolerance in the previous procedure.
The adjustment for calibrating the meter requires disassembling the meter.
Refer to the diagrams and access procedures in the 80 Series Service
Manual.
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.
3. Connect a set of test leads to the DMM as shown in Figure 4-19.
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
6. Set the DMM function switch to 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
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
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
How to Test 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 Calibrator.
These procedures are included here as an example. The Model 41 Service
Manual contains the complete authoritative testing and calibration
procedures
