For Fluke 117 with S/N 38920290 through 42913406, use this alternate calibration procedure to verify that
VoltAlert functions properly. See Figure 5.
1. Select the VoltAlert function:
a. Verify that Hi is on the display.
b. Verify that the beeper is silent and the red LED is off.
2. Connect wire (Pomona 4911A-12-2 or equivalent) to the High output voltage terminals of the calibrator
(Fluke 5500A or equivalent).
3. Set the calibrator output to 10 V at 60 Hz.
4. Hold the Meter so that the wire contacts and runs across the top center of the unit. The wire should run
perpendicular to the face of the unit (front to back of Meter, not side to side). Verify that the Meter beeper is
on continuously and the red LED, at the top of the display, lights up.
5. Place the calibrator in standby mode and verify that the beeper is silent and the red LED is off.
6. Press q.
Display should indicate
Lo range.
7. Set the calibrator output to 30 V at 60 Hz.
8. Hold the Meter so that the wire contacts and runs across the top center of the unit. The wire should run
perpendicular to the face of the unit (front to back of Meter, not side to side). Verify that the Meter beeper is
on continuously and the red LED, at the top of the display, lights up.
9. Return the calibrator to standby mode and verify the Meter’s beeper is silent and the red LED is off.
