Calibration Manual

Note

Verification tests for the 787 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 verification test manually.

Computer-Automated Verification Test Procedures

Computer-automated verification test procedures for the 787 ProcessMeter are available.

These procedures require Fluke’s MET/CAL Calibration Software version 6.0 or later, a
787 Calibration Module, a Fluke 5500A or 5520A Calibrator, and either an HP 34401A
multimeter or an HP 3458A multimeter. Note that the HP 34401A may only be used in
conjunction with the 5520A Calibrator.

The procedures are:

•

 

Fluke 787

: (1 year) CAL VER /5500, 3458

•

 

Fluke 787: (

1 year) CAL VER /5520, 34401

Preparing to Perform the Verifications Tests

W

Warning

To avoid possible electric shock or personal injury:

•

 

DO NOT use the ProcessMeter or the 787 Calibration Module if
either looks damaged.

•

 

Before proceeding with the verification tests, inspect the
ProcessMeter and the Calibration Module for damage, especially
around the input terminals.

•

 

Look for cracks, missing plastic, or damaged insulation. If damage
is detected, do not continue; contact Fluke to arrange to have the
ProcessMeter or Calibration Module serviced.

•

 

Make sure that the battery door on the ProcessMeter is closed and
latched before using the ProcessMeter.

•

 

Inspect the test leads and test connections for damaged insulation
or exposed metal.

•

 

Check the test leads for continuity. Replace damaged test leads as
necessary.
