Preparation - Fluke ProcessMeter 789 Calibration Manual

designated values, and determine if the reading on the ProcessMeter or the multimeter
falls within the acceptable range indicated.
These calibration verification test procedures assume that the person performing the
tests has read the 789/787B Users Manual, knows how to select functions and ranges on
the ProcessMeter, and knows how to operate the required equipment.
Calibration verification tests for the ProcessMeter can be performed
manually, or they can be computer-automated (using Fluke's MET/CAL
Calibration Software). This document provides the procedures necessary to
perform the calibration verification test manually.

Preparation

Throughout the calibration verification tests, "UUT" (unit under test) refers
to the ProcessMeter; the word "multimeter" is reserved for the digital
multimeter identified in the required equipment listed in Table 2.
Unless otherwise indicated, all connection diagrams for the calibration
verification tests in this manual showing a calibrator or digital multimeter
use a Fluke 5522A calibrator or 8508A.
If using a different calibrator or DMM make the connections appropriate for
your instrument.
To prepare the UUT for the calibration verification tests:
1. Make sure that the required equipment is available (see Table 2).
2. Make sure that the fuses in the UUT are intact. See "Checking and Replacing a
Fuse" earlier in this manual.
3. Make sure the UUT has fresh batteries. See "Replacing the Batteries" earlier in this
manual.
4. Warm up the calibrator and multimeter as required by their specifications.
5. Remove all input cables from the front of the UUT.
6. Make sure that the UUT is in a stable ambient temperature between 18 °C and 28 °C
(64.4 °F and 82.4 °F) and that it has been warmed up for 5 minutes.
