TB 9-6625-2361-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification. This procedure provides instructions for 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 procedure.
a. Model Variations. None.
b. Time and Technique. The time required for this calibration is approximately 2
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.
