(9) Repeat (2) through (7) above, except use fuel quantity No. 2 controls.
b. Adjustments. No adjustments can be made.
11. Turbine Gas Temp No. 1 and No. 2
a. Performance Check
(1) Connect multimeter to connector No. 1 pins L (HI) and M (LO).
(2) Set TURBINE GAS TEMP 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 33.65 (33.69) and 33.95 (33.89) mV dc.
(4) Set TURBINE GAS TEMP NO. 1 HI/LO switch to LO.
Multimeter will
indicate between -0.50 (-0.10) and +0.50 (+0.10) mV dc.
(5) Set TURBINE GAS TEMP NO. 1 CAL/NOR switch to NOR and adjust
variable control fully ccw. Multimeter will indicate between -0.50 and +0.50 mV dc.
(6) Adjust variable control fully cw. Multimeter will indicate 41.30 mV dc minimum
(between 41.30 and 51.30 mV dc).
(7) Set ON-OFF-SIM ONLY switch to OFF.
(8) Disconnect leads from connector No. 1 pins L (HI) and M (LO) and connect to
connector No. 2 pins L (HI) and M (LO).
(9) Repeat (2) through (7) above except use TURBINE GAS TEMP NO. 2 controls.
b. Adjustments. No adjustments can be made.
12. Engine Oil Temp No. 1 and No. 2
a. Performance Check
(1) Connect multimeter Input (2 Wire) HI and LO to connector No. 1 pins g (HI)
and h (LO) and connect multimeter Ω Sense (4 wire) HI and LO to connector No. 1 pins g
(HI) and h (LO). In addition, connect multimeter Guard to connector No. 1 pin h (LO).
(2) Set multimeter for 4-wire ohms measurement mode.
(3) Set ENGINE OIL TEMP NO. 1 CAL/NOR switch to CAL and HI/LO switch to
HI. On model 476-854, adjust ENGINE OIL TEMP NO. 1 CAL/NOR variable control
fully cw.
(4) Measure resistance. Multimeter will indicate between 148 Ω (150.2 Ω) and
154 Ω (151 Ω).
(5) Set ENGINE OIL TEMP NO. 1 HI/LO switch to LO. Multimeter will indicate
between 71 Ω (75.3 Ω) and 77 Ω (75.9 Ω).
(6) On model 476-853, set ENGINE OIL TEMP NO. 1 CAL/NOR switch to NOR
and adjust variable control from fully ccw to fully cw. Multimeter indication will vary from
77 Ω or less to 148 Ω or more.
