IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin provides instructions for the
calibration of A31U12661-3, Self-Alignment Interface Connection Device. The Calibration
and Measurements Requirements Summary (CMRS) IFTE89P630305-00, dated 11 May
1993, and TM 11-6625-3267-24&P were used as the prime data sources 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
4 hours, using the dc and low frequency technique.
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 are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables the (R) follows the designated adjustment.
