2. Verify that the EARTH indicator is lit; if not, press Z.
3. Set the calibrator output to 5.0 V at 60 Hz on the NORMAL output and 30 mV at
60 Hz on the AUX output.
4. Press the WAVE MENUS ,then the φ & REF MENUS softkey on the calibrator.
Ensure the AUX φ NRM angle is 0.00 degrees. Press O.
5. Select W from VAW on the Tester.
6. Press the mode button on the Tester for the text screen mode. Verify that the W/KW,
VA/KVA, and VAR/KVAR readings are within the minimum and maximum limits
specified in Table 4-3.
7. Press the mode button on the Tester for the harmonics screen mode. Verify that the
fundamental frequency phase angle readings are between the minimum and
maximum readings listed in Table 4-3.
8. Repeat the previous three steps using the calibrator outputs and performance limits
listed in Table 4-3.
9. Press Y on the calibrator to remove the voltage from the Tester.
How to Test Harmonics Volts Performance
1. Press the mode button on the Tester for the harmonics screen.
2. Press the VAW button on the Tester until V is displayed above the upper right corner
of the harmonics screen.
3. Press the VAφ REF button on the Tester until AΦ is displayed in the top status line.
4. Press the SMOOTH button on the Tester until ~20s is displayed in the top status
line.
5. Connect the calibrator NORMAL output to the V and COM connectors on the Tester.
6. Connect the calibrator AUX output to the Current Probe connector on the Tester.
7. Set the calibrator output to 7.0 V at 60 Hz on the NORMAL output and 700 mV at
60 Hz on the AUX output. Press the WAVE MENUS, then the Φ & REF MENUS
softkey and ensure the phase angle is -10.0 degrees. Press the HARMONIC MENU
softkey and ensure the HARMONIC selection is set to “1” and the FUNDMTL
selection is set to “aux.” Press O.
8. Move the Tester cursor to the corresponding harmonic number.
9. Verify that the harmonic amplitude and phase angle readings displayed by the Tester
are within the minimum and maximum limits listed in Table 4-4. (Note: The Tester
will read a positive phase when the Calibrator output is a negative phase because, on
the Calibrator, the polarity of the phase is always relative to the NORMAL channel
output.)
10. Repeat the previous three steps using the settings and limits in Table 4-4.
