4.3.12.9.3 +10 VDC Reference. - Connect a DVM between J3-T and J3-A
with pin A at ground. Measure 10 0.1 VDC.
4.3.12.9.4 Target blanking. - Connect an oscilloscope between J3-S
and J3-A witn pin A at ground. Place the Smoke/Normal switch on the rear
of the console in the Normal position. Measure a logical "0" on the scope.
4.3.12.9.4.1 Depress the Manual Mode and Fire 1 indicators. The Fire
1 indicator shall light and the scope shall read a logical "O". Reset the
console.
4.3.12.9.4.2. Apply a +18 0.1 VDC signal on J1-c with J1-s at ground.
Place the Smoke/Normal switch in Smoke. Repeat 4.3.4.1. The scope shall
indicate a logical "1".
4.3.12.9.4.3 Remove the +18 VDC signal. The output on J3-s shall re-
turn to logical "1".
