Calibration Information

Testing the Capacitance Function

1. Set the UUT to Ω E and connect the decade capacitor output to the VΩG and COM input terminals
of the UUT.
2. Press the yellow button to select the capacitance function.
3. Referring to Table 8, set the decade capacitor for the output indicated in the steps. Verify that the UUT
display reading is within the limits shown.

* Conducting performance tests of the 400 Ω, 4 kΩ, 40 kΩ and 10 µF ranges verifies that the discrete and
integrated circuitry needed to support the other capacitance ranges are working within specifications.
Therefore, these tests indirectly verify that the meter will meet specification in the 10 µF, 100 µF, 1000 µF,
and 10,000 µF ranges.

Testing the Continuity Function

1. Set the UUT to 40Ω ( R G).
2. Press the yellow button to select the continuity test function.
3. Referring to Table 9, apply a short as indicated. Verify that the UUT display and beeper indicate as
shown.
