33.
Set selector switch knob (3) to FWD.
34.
Adjust resistors (11, 12, 13, 14, and 15) to 100
percent (full counterclockwise).
35.
Adjust FWD resistor (11) clockwise until indicator
(5) reads 50 psi.
36.
Set selector switch knob (3) to AFT.
37.
Adjust AFT resistor (12) clockwise until indicator
(5) reads 15 psi.
38.
Set selector switch knob (3) to FWD. Check
indicator (5). Pointer of indicator shall move to 15
psi in less than 5 seconds.

case ground and pin K of indicator (5).
43.
Adjust FWD resistor (11) clockwise until indicator
(5) reads 95 psi.
44.
Continue to adjust FWD resistor (11) clockwise.
Check multimeter (1). Multimeter shall indicate
continuity when indicator (5) reads 21.5 to
