SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Analog Multimeters 0 to 6000 Volts (General) listed in table 1. The
manufacturers' manuals or TMs were used as the prime data sources in compiling these
instructions. The equipment being calibrated will be referred to as the TI (test instrument)
throughout this bulletin.
a. Model Variations. Variations among models are described in text, tables and figures.
b. Time and Technique. The time required for each calibration is approximately 2
hours, using the dc and low frequency technique.
2. Forms, Records, and Reports
a. Forms, records, and reports required for calibration personnel at all levels are
prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables, the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
3. Calibration Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.

EQUIPMENT REQUIREMENTS
4. Equipment Required. Table 2 identifies the specific equipment to be used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-286; AN/GSM-287; or AN/GSM-705. Alternate items may be used
by the calibrating activity. The items selected must be verified to perform satisfactorily
prior to use and must bear evidence of current calibration. The equipment must meet or
exceed the minimum use specifications listed in table 2. The accuracies listed in table 2
provide a four-to-one ratio between the standard and TI. Where the four-to-one ratio
cannot be met, the actual accuracy of the equipment selected is shown in parenthesis.
5. Accessories Required. The accessories required for this calibration are common
usage accessories issued as indicated in paragraph 4 above, and are not listed in this

CALIBRATION PROCESS
6. Preliminary Instructions
a. The instructions outlined in paragraphs 6 and 7 are preparatory to the calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
name as listed in table 2.

TB 9-6625-2352-24
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturers' manuals and/or technical
manuals for the TI.
d. This is a general procedure which provides instructions for the calibration of a
variety of multimeters.
e. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE

1 Replace calibrator with power supply and move positive lead to TI 5000 V input. Calibrate at 900 V if power supply is not
available. After 5000 V check is complete, reduce output to minimum, replace power supply with calibrator and move positive
lead to TI V-Ÿ-A input.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
