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, AN/GSM-287, or AN/GSM-705. 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.
5. Accessories Required. The
accessories required for this
calibration are common
usage accessories issued as indicated in paragraph 4 above and are not listed in this

6. Preliminary
Instructions
a. The
instructions outlined in
paragraphs 6 and
7 are preparatory to the
calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
c. Unless otherwise specified, verify the result of each test and, whenever the test
requirement is not met, take corrective action before continuing with the calibration.
Adjustments required to calibrate the TI are included in this procedure. Additional
maintenance information is contained in the manufacturers' manuals for this TI.
d. Unless otherwise specified, all control and control settings refer to the TI.
