Section V. PERFORMANCE VERIFICATION

5-26. Introduction. The procedure outlined in this section should be followed to ensure that the MTS test aid is

functioning properly.

5-27. Functional Test Procedure. The functional test procedure includes required test equipment, initial conditions,

ohmmeter checks, and main test.

a. Required Test Equipment.

(1) Oscilloscope OS-261/U (NSN 6625-00-127-0079)

(2) Power Supply HP 6268B (NSN 6130-00-249-2748) or equivalent: 5v at 5amps.

(3) Digital Voltmeter AN/USM-451 (NSN 6625-00-168-0585) or equivalent.

NOTE

The HP 6268B power supply requires an operating voltage of 115v + 10%, 60 Hz, single phase.

b. Initial Conditions.

(1) Turn DATA/FUNCTIONAL/CONT switch to FUNCTIONAL.

(2) Set SS switch to up position.

(3) Set BCP switch to up position.

(4) Turn power supply on.

(5) Adjust power supply to + 5.50 + 0.25v (no-load condition).

(6) Turn power supply off.

(7) Connect power supply to MTS test aid binding posts (CAL + 5V and GND).

c. Ohmmeter Checks.

(1) Measure resistance between J01-107 and GND (black binding post); resistance should be less than one ohm.

(2) Set SS switch to down position.

(3) Measure resistance between J01-107 and GND; an open reading should be indicated.

(4) Measure resistance between J0J-109 and GND; resistance should be less than one ohm.

(5) Set BCP switch to down position.

(6) Measure resistance between J0J-109 and GND; an open reading should be indicated.
