Fluke 1587 - Performance Test; Testing DMM Functions

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 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 3.
3. Apply the input level for each step listed in Table 3.
4. Compare the reading on the UUT display with the Display Reading in
Table 3.
If the display reading falls outside of the range shown in Table 3, the UUT
does not meet specification.
