Testing Memory Mode Performance (Model 41B Only); Testing Harmonics Volts Performance - Fluke 39 Service Manual

4-10. Testing Memory Mode Performance (Model 41B Only)

1. Using the equipment setup from the previous performance test, apply the last set of
values from Table 4-4 to the Tester.
2. Press m.
3. Using < > and E, Clear, store, and recall the waveform in memory.

4-11. Testing Harmonics Volts Performance

Make sure that the unit is set to "THD % RMS" before performing this
procedure.
1. Press M until the harmonics screen is displayed on the Tester.
2. Press F until V is displayed above the upper right corner of the harmonics display.
3. Press f until AP is displayed in the top status line of the Tester.
4. Press S until %20s is displayed in the top status line of the Tester.
5. Connect the calibrator NOTMAL output to the V and COM connectors on the
Tester.
6. Connect the calubrator AUX output to the Current Probe connector on the Tester.
7. Set the calibrator output to 7.0V at 50 or 60 Hx on the NORMAL output and 700
mV at the same frequency on the AUX output. Press the WAVE 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.", the Press OPR.
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 4-5.
The polarity of the phase on the 5500A is always relative to the NORMAL
channel output. Therefore,the Tester will read a positive phase when the
5500A output is a negative phase.
10. Repeat the previous three steps using the settings and limits in Table 4-5.
