Equipment Required for Performance Tests
The following equipment is required for performance tests:
• Fluke 5500A Multi-Product Calibrator, or equivalent
• 0 V to 5 V adjustable dc power supply
• Approximately 8 m (26 ft) of #14 single-conductor magnet wire wound into a butterfly-shaped coil.
Figure 1 shows how to make the coil.
Performance Tests
Use the following procedures to verify the tester’s performance. If the tester fails any of the tests, return it to
Fluke for calibration or repair.
Testing the AC Current Function
The tests in this section require the butterfly coil shown in Figure 1. Note that the 10 conductors in the middle
of the coil cause the tester to read 10 times more current than the calibrator supplies.
1. Put one edge of the butterfly coil in a vice to hold the coil during testing.
2. Set the calibrator to the current and frequency given in Step 1 of Table 1.
3. Connect the butterfly coil to the calibrator.
4. Set the tester to the amperage function.
5. Place the tester’s current fork around the middle of the coil so that the alignment marks are centered and
perpendicular to the wire bundle, as shown in Figure 1.
6. Verify that the tester reads within the display limits shown for Step 1 in Table 1.
7. Apply the currents and verify the tester’s readings for the remaining steps in Table 1.
