9. Torque No. 1 and No. 2

NOTE

Values in parenthesis pertain to Model 476-854.

a. Performance Check

(1) Set ON-OFF-SIM ONLY switch to OFF.

(2) Connect multimeter to TI connector No. 1 pins E (HI) and F (LO). Refer to

figure 2 for pin locations.

(3) Set TORQUE NO. 1 CAL/NOR switch to CAL and HI/LO switch to HI.

(4) Set ON-OFF-SIM ONLY switch to SIM ONLY.

Multimeter will indicate

between 3.6 (3.6963) and 3.8 (3.7037) V dc.

(5) Set TORQUE NO. 1 HI/LO switch to LO. Multimeter will indicate between

-0.1 (-0.0001) and +0.1 (+0.0001) V dc.

(6) Set TORQUE NO. 1 CAL/NOR switch to NOR and turn variable control fully

ccw. Multimeter will indicate between -0.1 (-0.003) and +0.1 (+0.003) V dc.

(7) Adjust variable control fully cw. Multimeter will indicate 5.415 V dc minimum

(between 5.415 and 5.815 V dc).

(8) Set ON-OFF-SIM ONLY switch to OFF.

(9) Disconnect leads from connector No. 1 pins E (HI) and F (LO) and connect to

connector No. 2 pins a (HI) and b (LO).

(10) Repeat (3) through (8) above, except use TORQUE No. 2 controls.

b. Adjustments. No adjustments can be made.

10. Fuel Quantity No. 1 and No. 2

a. Performance Check

(1) Connect multimeter to connector No. 1 pins G (HI) and H (LO).

(2) Set FUEL QUANTITY NO. 1 CAL/NOR switch to CAL and HI/LO switch to HI.

(3) Set ON-OFF-SIM ONLY switch to SIM ONLY.

Multimeter will indicate

between 6.08 (6.12) and 6.18 (6.13) V dc.

(4) Set FUEL QUANTITY NO. 1 HI/LO switch to LO. Multimeter will indicate

between -0.1 (-0.001) and +0.1 (+0.001) V dc.

(5) Set FUEL QUANTITY NO. 1 CAL/NOR switch to NOR and adjust variable

control fully ccw. Multimeter will indicate between -0.1 (-0.01) and + 0.1 (+0.01) V dc.

(6) Adjust variable control fully cw. Multimeter will indicate 7.63 V dc minimum

(between 7.63 and 8.03 V dc).

(7) Set ON-OFF-SIM ONLY switch to OFF.

(8) Disconnect leads from TI connector No. 1 pins G (HI) and H (LO) and connect to

connector No. 2 pins G (HI) and H (LO).
