TEST POINTS

Provide monitoring capability for functional conditions of stabilator system

operation. NO. 1 test points relate to No. 1 stabilator amplifier, and NO. 2 test

points relate to No. 2 stabilator amplifier.

drive in driver logic module turns on to command actuator. Each test point

voltage may be 15 vdc or 0 vdc.

NO. 1 and NO. 2 STAB

Provide monitoring capability for voltages supplied by No. 1 and No. 2 stabila-

is in manual slew mode, test points have steady 28 vdc. When system is in

automatic mode, test points have 0 vdc to 28 vdc pulse with modulation.
