SECTION I
IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
1. Test Instrument Identification.
calibration of Voltage Standard, John Fluke Models 332A, 332B, and 332B/AF. The
manufacturers instruction manuals were 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. On model 332A with serial numbers 123 through 332, the X
position of voltage dials 2 through 7 is labeled 10.
b. Time and Technique. The time required for this calibration is approximately 4
hours, using the dc and low frequency technique.
2. Calibration Data Card, DA Form 2416
a.
Forms, records, and
reports required for calibration personnel at all
levels are
prescribed by TM 38-750. DA Form 2416 must be annotated in accordance with TM 38-750
for each calibration performed.
b. Adjustments to be reported on DA Form 2416 are designated (R) at the end of the
sentence in which they appear. When adjustments are in tables, the (R) will follow 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.
