TB 9-6625-2327-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin 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 bulletin.
a. Model Variations. None.
b. Time and Technique. The time
required for this
calibration is
approximately 5
hours, using the dc and low frequency and microwave techniques.
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. All adjustments that are made as a result of an out-of-
tolerance condition are reportable. Any adjustments that are made as a result of the
normal cyclic calibration are not reportable
3. Calibration
Description. TI
parameters and
performance specifications which
pertain to this calibration are listed in table 1.
