IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin
provides instructions for the
calibration of Pressure Gage Testers MIL-T-2746B, Mansfield and Green Model 10-10525
(8598963 and 8491213 Manning, Maxwell, and Moore Model 1305B-100 and Ametek
Model R100. The manufacturer's instruction manual was used as the prime data source
in compiling these instructions. The equipment being calibrated will be referred to as
"TI" (test instrument) throughout this bulletin.
a. Model Variations. The handpump and accessories are basically the same for all
units. Pressure gage tester, Manning, Maxwell, and Moore Model 1305B-100 is
designated to develop nominal pressure at standard gravity (980.665 cm/sec2). Pressure
gage tester Mansfield and Green Model 10-10525 1398963 and 8491213) are designed to
develop nominal pressure at a gravity of 980.217 cm/sec2 or 980.665 cm/sec2. The gravity
used in design is normally printed on the name tag in the pump carrying case. When
replacing the piston and cylinder combination, specify the design gravity according to
the name tag. The Ametek Model R100 is a replacement for the Mansfield and Green,
Model 10-10525.
b. Time and Technique . The time required for this calibration is approximately 8
hours, using the physical 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.
