Minimum use specifications are the principal parameters required for performance of the calibration, and are
included to assist in the selection of alternate equipment, which may be used at the discretion of the using
laboratory. Satisfactory performance of alternate items shall be verified prior to use. All applicable
equipment must bear evidence of current calibration.
The instruments utilized in this procedure were selected from those known to be available at Navy
calibration facilities, and the listing by make or model number carries no implication of preference,
recommendation, or approval for use by other agencies. It is recognized that equivalent equipment produced
by other manufacturers may be capable of equally satisfactory performance in this procedure.
If the TI has an electronic counter function, calibration is in two parts: First, calibrate the TI electronic
counter function in accordance with NAVAIR 17–20VF–06; then calibrate the multimeter function with this
procedure.
