Required Equipment; Preparing For The Performance Test - Fluke 77 Calibration Information Manual

Required Equipment

A Fluke 5500A Multi-Product Calibrator (or equivalent) is required for the performance test procedures in
this document.
If an equivalent calibrator is used, it must meet the accuracy specifications shown in Table 1.

(or equivalent)

Preparing for the Performance Test

To avoid possible electric shock or personal injury:
•
Do not perform the following procedures unless qualified to do so. Some
procedures involve the use of high voltages.
•
Before handling the test connections, and in between tests, make sure the
calibrator is in standby (STBY) mode.
•
Do not perform the performance test procedures unless the Meter is fully
assembled
To prepare for the performance test:
1. Make sure that you have the required equipment (refer to Table 1).
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the UUT to stabilize at room temperature ( 23 °C ± 5 °C [73 °F ± 9 °F] ).
4. Check the fuses and Battery, and replace them if necessary. Refer to Testing the Fuses, Replacing the
Fuses, and Replacing the Battery.
