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.

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.

calibration procedure. This equipment is issued with Secondary Transfer Calibration

Standards Set AN/GSM-286, and AN/GSM-287. 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.

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 procedure.

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.

3

TB 9-6625-2352-35

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

OUTPUT(S) to minimum after each step within the performance check where applicable.

a. If necessary, mechanically zero meter pointer, using adjustment screw on meter face.

b. Connect test leads to TI COM ( −) and VOA (+) jacks.

8. Dc Voltage

(1) Set function switch to dc volts and range switch to first dc voltage range listed in calibration performance specifications and adjustments table for TI being calibrated.

(2) Connect TI to calibrator OUTPUT HI and OUTPUT LO, observing polarity.

(3) Set calibrator to initial output as listed in table.

(4) Rotate calibrator knob, below EDIT FIELD pushbutton, for the required indication on TI. If calibrator displayed output does not indicate within limits specified, and an adjustment is listed, adjust calibrator for nominal value and then perform adjustment for required indication on TI.

(5) Repeat technique of (1), (3) and (4) above for the remaining dc voltage ranges.

9. Ac Voltage

(1) Set function switch to ac volts and range switch to first ac voltage range listed in calibration performance limits and adjustments table for TI being calibrated.

(2) Set calibrator to initial output and frequency as listed in table.

4

TB 9-6625-2352-35

adjustment is listed, adjust calibrator for nominal value and then perform adjustment for required indication on TI.

(4) Repeat technique of (1), (2) and (3) above for the remaining ac voltage ranges.

10. Resistance

(1) Set function switch to ohms and range switch to first ohms range listed in calibration performance limits and adjustments table for TI being calibrated.

(2) Short test leads together and adjust ohms adjust for a 0 indication on TI ohms scale.

(3) Connect TI to resistance standard NO. 1.

(4) Adjust resistance standard for required indication on TI as listed in table. If resistance standard does not indicate within limits specified, and an adjustment is listed, adjust resistance standard for nominal value and perform adjustment for required indication on TI.

(5) Repeat technique of (1), (2) and (4) above for the remaining ohms ranges.

11. Dc Current

(1) Set function switch to dc amps and range switch to the first dc current range listed in the calibration performance specifications and adjustments table for the TI being calibrated.

(2) Set calibrator to initial output as listed in table.

(3) Rotate calibrator knob, below EDIT FIELD pushbutton, for the required indication on TI. If calibrator err display does not indicate within limits specified, and an adjustment is listed, adjust calibrator for nominal value and then perform adjustment for required indication on TI.

(4) Repeat technique of (1) through (3) above for the remaining dc current ranges.
