SECTION I
IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
1. Test Instrument Identification.
calibration of Torque Wrench, Raymond Engineering, Inc., Model PD 730.
The
manufacturer's manual 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 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.

SECTION II
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 the
standard and TI. Where the four-to-one ratio cannot be met, the four-to-one accuracy will
be listed and the actual accuracy of the equipment selected shown in parenthesis.
