4-61. Testing Harmonics Amps Performance

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 60 Hz on the NORMAL output and 20 mV at 60
Hz 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."
Press .
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.

4-62. Calibrating a Fluke 51 Thermometer

The Fluke 51 Thermometer measures temperature using a type J or K thermocouple. The
calibrator simulates both thermocouples, simplifying testing and calibration. The
following demonstrates how the calibrator is used to calibrate this thermometer.
These procedures are included here as an example. The Model 51 Service
Manual contains the authoritative testing and calibration procedures.
