TB 9-5885-1892-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Thermal Sight Collimator SM-D-969722 (12591545). The manufacturer's
procedure document number 6004651, dated 01 July 1996, Revision B, 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 3
hours, using the physical 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.
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.
Test instrument parameters
Performance specifications
Temperature differential
Temperature: 4.5 C (ambient to heater)

EQUIPMENT REQUIREMENTS
4. Equipment Required. Table 2 identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-286. Alternate items may be used by the calibrating activity when
the equipment listed in table 2 is not available. The items selected must be verified to
perform satisfactorily prior to use and must bear evidence of current calibration. The
equipment must meet or exceed the minimum use specifications listed in table 2. The
accuracies listed in table 2 provide a four-to-one ratio between the standard and TI.
