SECTION I

IDENTIFICATION AND DESCRIPTION

1. Test Instrument Identification. This bulletin provides instructions for the

calibration of Test Set, Aviator's Night Vision Imaging System, TS-3895A/UV. TM 11-

5855-264-14 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 1

hour, 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.

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.

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.

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 standard and TI.
