4-1. Introduction
This chapter of the Service Manual provides performance tests that can be used at any
time to verify Fluke 45 operation within published specifications. A complete calibration
procedure is also included. The performance test and, if necessary, the calibration
procedure can be performed periodically and after service or repair.
4-2. Required Equipment
Equipment required for performance testing and calibration is listed in Table 4-1.

Note
The 5700A Calibrator can be used for 0.05% accuracy (rated) on the
3.0 k
Ω , 30 k Ω , 300 k Ω , and 3.0 M Ω ranges. This calibrator can be used
for 0.06% accuracy on the 100
Ω and 300 Ω ranges.
