4-12. Testing Harmonics Amps Performance
Note
Make sure that the unit is set to "THD % RMS" before performing this
procedure.
1. Press F until A is displayed above the upper right corner of the harmonics display.
2. Press f until VP is displayed in the top status line of the Tester.
3. Press S until %20s is displayed in the top status line of the Tester.
4. Connect the calibrator NORMAL output to the V and COM connectors on the
Tester.
5. Connect the calibrator AUX output to the Current Probe connector on the Tester
6. Set the calibrator output to 7.0 V at 50 or 60 Hz on the NORMAL output and 20 mV
at the same frequency on the AUX output. Press the WAVE MENUS softkey and
ensure the phase angle is 10.00 degrees. Press the HARMONIC MENU softkey and
ensure the HARMONIC selection is set to "1" and the FUNDMTL selection is set to
"normal", then press OPR.
7. Verify that the harmonic amplitude and phase angle readings displayed by the Tester
are within the minimum and maximum limits listed in Table 4-6.
