EQUIPMENT REQUIREMENTS
NOTE
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

4.5.2 Set the TI AC output control(s) to obtain an output of 10V at 400 Hz and set the thermal transfer standard
(TTS) range switch to 10V.
4.5.3 Set the TTS mode switch to the ac transfer position. Establish a galvanometer null at its most sensitive

galvanometer null.

4.5.7 Obtain a null indication successively in the medium” and high” positions of the TTS sensitivity switch
by adjusting the dc voltage standard output control(s).
4.5.8 Allow 15 to 30 seconds for the galvanometer to stabilize. Verify that the dc voltage standard output
indication is within 9.996 to 10.004 volts.

steps 4.8.3 through 4.8.9 and the checklist. Verify at each measurement of the TI decade dial resistance setting
that the measuring system decade resistance dial indication is within the tolerance limits listed.
