2.
Make sure that the EARTH indicator is illuminated. If not, push
.
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.
Push the WAVE MENUS, then the
φ
& REF MENUS softkey on the Calibrator.
Make sure the AUX
φ
NRM angle is 0.00 degrees. Push
.
5.
Select W from VAW on the Tester.
6.
Push the mode button on the Tester for the text screen mode. Verify that the W/KW,
VA/KVA, and VAR/KVAR indications are in the minimum and maximum limits
specified in Table 4-4.
7.
Push the mode button on the Tester for the harmonics screen mode. Verify that the
fundamental frequency phase angle indications are between the minimum and
maximum indications given in Table 4-4.
8.
Do step 5, 6, and 7 again and use the Calibrator outputs and performance limits
shown in Table 4-4.
9.
Push
on the Calibrator to remove the voltage from the Tester.
Verify Harmonics Volts Performance
1.
Push the mode button on the Tester for the harmonics screen.
2.
Push the VAW button on the Tester until V is shown above the upper-right corner of
the harmonics screen.
3.
Push the VA
φ
REF button on the Tester until A
Φ
is shown in the top status line.
4.
Push the SMOOTH button on the Tester until ~20s is shown 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. Push the WAVE MENUS, then the
Φ
& REF MENUS
softkey and make sure the phase angle is -10.0 degrees. Push the HARMONIC
MENU softkey and make sure the HARMONIC selection is set to “1” and the
FUNDMTL selection is set to “aux.” Push
.
8.
Move the Tester cursor to the necessary harmonic number.
9.
Make sure that the harmonic amplitude and phase angle indications shown by the
Tester are in the minimum and maximum limits shown in Table 4-5.
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
relative to the NORMAL channel output.
10.
Do steps 7, 8, and 9 again and use the values and limits in Table 4-5.
