SECTION III

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.

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 TM 11-6625-3165-14 for this TI.

d. When indications specified in paragraphs 7 through 18 are not within tolerance,

perform the power supply check prior to making adjustments. After adjustments are made,

repeat paragraphs 7 through 18. Do not perform power supply check if all other

parameters are within tolerance.

e. Unless otherwise specified, all controls and control settings refer to the TI.

7. Equipment Setup

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.

NOTE

Before connecting TI, the protective earth terminal of the

instrument must be connected to the protective conductor of

the line power cord. The line plug shall only be inserted in a

socket outlet provided with a protective earth contact. The

protective action must not be negated by the use of an

extension cord (power cable) without a protective conductor

(grounding). Grounding one conductor of a two-conductor

outlet is not sufficient protection.
