Performance Test; Testing The 1577 And 1587 Dmm Functions - Fluke 1587 Calibration Manual

1587/1577
Calibration

Performance Test

The following series of tests comprise a performance test for verifying the accuracy
of the Meter (UUT) and its performance level. The performance test is recommended
as an acceptance test for incoming inspection and as a calibration procedure for
periodically ensuring the accuracy of the Meter. Fluke recommends running the
performance test at least once a year.
No adjustments are required during the performance test, and it is not necessary to
open the case. If the Meter does not pass all parts of the performance tests, repair
and/or calibration adjustment are required. A calibration adjustment procedure is
given later in this manual. If significant repairs are required, contact Fluke as
described toward the front of this manual. If user repairs are appropriate, refer to the
list of user-replaceable parts toward the end of this manual

Testing the 1577 and 1587 DMM Functions

Use the following procedure to verify the accuracy of the measurement functions.
1. Connect the Calibrator to the J and COM input terminals on the UUT.
2. Turn the rotary switch to the function listed in each step of Table 2.
3. Apply the input level for each step listed in Table 2.
4. Compare the reading on the UUT display with the Display Reading in Table 2.
If the display reading falls outside of the range shown in Table 2, the UUT does
not meet specification.
