4-3. Performance Tests
The following performance tests are provided to ensure that the meter is in proper
operating condition. If the meter fails any of the performance tests, calibration
adjustment and/or repair is needed. To perform these tests, you will need a Fluke 5700A
Multifunction Calibrator and a 5725A Amplifier or equipment meeting the minimum
specifications given in Table 4-1.
Each of the measurements listed in the following steps assumes the meter is being tested
after a one-hour warmup in an environment with an ambient temperature of 18 to 28ºC
and a relative humidity of less than 90% (70% for MΩ ranges). The limits in Table 4-2
represent the 1-year calibration cycle.
Note
All measurements listed in the performance test tables are made in the
medium reading rate unless otherwise noted.
1. Power up the meter and allow it to stabilize for one hour.
2. Connect a cable from the Output VA HI and LO connectors of the 5700A to the
X and COM connectors on the Fluke 45. Select the function and range on the
Fluke 45 and the input level from the 5700A using the values listed in Table 4-2. The
display should read between the minimum and maximum values listed in the table.
3. Connect a cable from the Output VA HI and LO connectors of the 5700A to the
[100 mA] and COM connectors on the Fluke 45. Select the function and range on the
Fluke 45 and the input level from the 5700A using the values contained in Table 4-3.
The display should read between the minimum and maximum readings listed in the
table.
4. The following tests require a Fluke 5725A Amplifier (or equivalent) to be used with
the 5700A. The input level for the performance test will be set on the 5700A but will
be output from the 5725A Amplifier.
Connect a cable from the Output VA HI and LO connectors of the 5725A to the [10 A]
and COM connectors on the Fluke 45. Select the function and range on the Fluke 45 and
the input level from the 5700A using the values contained in Table 4-4. The display
should read between the minimum and maximum readings listed in the table.
