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 440. Alternate items may be used

by the calibrating activity. The item 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

calibration procedure. The following peculiar accessory is also required for this calibration:

Automated Test Equipment (ATE) PN# 13625170 or Acceptance Test Equipment (ATE)

PN# 13675099, Instrument controller, or any computer with a standard serial port.
