SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin provides instructions for the calibration of environment control test set,
Grumman, Model A/E 24T-102. The manufacturer's manual was used as the prime data source in compiling these
instructions. The equipment being calibrated will be referred to as the TI (test instrument) throughout this bulletin.
a. Model Variations. None.
b. Time and Technique.
The time required for this calibration is approximately 6 hours, using the DC
technique.
2. DA Form 2416 (Calibration Data Card).
a. Forms, records, and reports required for calibration personnel at all levels are prescribed by TB 750-25. DA
Form 2416 must be annotated in accordance with TB 750-25 for each calibration performed.
b. Adjustments to be reported on DA Form 2416 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).
