Installing The 787 Calibration Module - Fluke ProcessMeter 787 Calibration Manual

The calibration procedures assume that the person performing them knows
how to use the 787 ProcessMeter and the required equipment. Do not
attempt to calibrate the ProcessMeter unless you are qualified to do so.
Throughout the following, "UUT" (unit under test) refers to the 787
ProcessMeter; the word "multimeter" is reserved for the digital
multimeter identified in the required equipment listed in Table 2.
Calibration should be performed in an RF field <1 V/m such as a
laboratory environment.
To prepare for calibration, do the following:
1. Make sure that you have the required equipment available (see Table 2 )and that the
MET/CAL Calibration Software is properly loaded on your PC.
2. Make sure that both fuses in the UUT are intact. See "Checking and Replacing
Fuses" earlier in this manual.
3. Connect the Calibrator to the PC using an IEEE-488 cable.
4. Turn on and warm up the calibrator as required by its specifications.
5. Remove all input cables from the front of the UUT.
6. Make sure that the UUT is in an ambient temperature between 18 C and 28 C
(64.4 F and 82.4 F).

Installing the 787 Calibration Module

During the calibration procedure, the UUT communicates over the battery cable with the
787 Calibration Module (hereafter referred to as the "Calibration Module") via a single-
duplex, RS-232 interface.
The Calibration Module contains a circuit that both optically isolates the computer's
communication port from the UUT and converts the RS-232 signals to the appropriate
format for communication with the UUT.
To avoid possible electrical shock or personal injury:
To maintain safe conditions during calibration, the 787 Calibration
Module must be properly attached to the UUT's battery lead
connector, and the battery door on the ProcessMeter must be
secured. See Figure 12.
When performing the following procedure, only use the battery
eliminator provided with the Calibration Module (see Table 2). A
generic battery eliminator might pose a safety hazard.
To install the 787 Calibration Module, do the following while referring to Figures 12 and
13 as necessary:
1. Remove all input cables from the front of the UUT and open the battery door on the
UUT.
2. Remove the battery from the battery receptacle of the UUT and unplug the battery
from the battery cable connector.
