SECTION I

IDENTIFICATION AND DESCRIPTION

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

calibration of Dial Indicators Transfer Level. The manufacturer's instruction manual

was used as the prime data source in compiling these instructions. The dial indicators

will be referred to as the TI (test instrument) throughout this bulletin.

a. Model Variations . Variations among models are described in text.

b. Time and Technique . The time required for this calibration is approximately

0.5 hour for each TI 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.
