Fluke ProcessMeter 787 Calibration Manual page 21

Do not use the ProcessMeter or the Calibration Module if either
appears to operate abnormally. Protection designed into the
ProcessMeter and Calibration Module might be impaired. If in
doubt have the ProcessMeter or Calibration Module serviced.
To avoid electrical shock, always place the calibrator in the
Standby (STBY) mode between tests and before handling the test
connections or test cables.
Some of the verification tests involve the use of high voltages and
should be performed by qualified personnel only.
These verification tests assume that the person performing them knows how
to use the 787 ProcessMeter and the required equipment.
Do not attempt to perform these tests unless you are qualified to do so.
Throughout the verification tests, "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.
Unless otherwise indicated, all connection diagrams for the verification
tests in this manual showing a calibrator or digital multimeter use a Fluke
5500A calibrator or HP 3458A.
If you are using a different calibrator or DMM make the connections
appropriate for your instrument.
To prepare the UUT for the verification tests, do the following:
1. Make sure that you have the required equipment available. (See Table 2.)
2. Make sure that both fuses in the UUT are intact. See "Checking and Replacing
Fuses" earlier in this manual.
3. Make sure the UUT has a fresh battery. See "Replacing the Battery" 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.
To avoid possible electrical shock or personal injury:
Some of the following tests involve the use of high voltages and
should be performed by qualified personnel only.
To avoid electrical shock always place the calibrator in the
Standby (STBY) mode between tests and before handling the test
connections.
