SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification
11154040 (TA114) and IR probe 10684700 (TA-437). Both items are portable test
equipment in the test station of the Land Combat Support System (LCSS). Throughout the
remainder of this bulletin, the item being calibrated will be referred to as the test
instrument (TI).
b. There is only one model of each of these TIs.
c. The time required for this calibration is approximately 3 hours using the IR
technique.
2. Calibration Data Card. Forms, records, and reports required for calibration
personnel at all levels are prescribed by TB 750-25. DA Form 2416 (Calibration Data
Card) must be annotated for each calibration performed.
