(5) Repeat (1) above.
(6) Set SW-8 switch to RX1000. If INSULATION CHECK meter does not indicate
zero, perform b (3) below.
(7) Adjust resistance standard for an indication of 100,000 ohms on INSULATION
CHECK meter. If
resistance standard does not
indicate between 90,000 and
110,000 ohms,
perform b (4) below.
(1) Adjust RX100 0 ADJ TRIMPOT for zero indication on INSULATION CHECK
meter (R).
(2) Adjust decade resistor for 10,000 ohms and adjust RX100-100 ADJ TRIMPOT
for INSULATION CHECK meter indication of 10,000 ohms (R).
(3) Adjust RX1000-0 ADJ TRIMPOT for zero indication on INSULATION CHECK
meter (R).
(4) Adjust RX1000-100 ADJ TRIMPOT for INSULATION CHECK meter
indication of 100,000 ohms (R).
a. Performance check
(1) Set SW-7 switch to MECH. ZERO.
(2) Adjust GALVO-2 MECH. ZERO 4 control for 0 indication.
(3) Adjust R.P.M. control for 0 indication on % dial.
(4) Set SW-7 switch to RANGE. If GALVO-2 does not indicate 0, perform b (1) below.
(5) Set SW-7 switch to MECH. ZERO.
(8) Adjust R.P.M. control to 100.0 as indicated on % dial.
(9) Set SW-7 switch to RANGE.
(10) Adjust audio analyzer frequency for 0 indication on GALVO-2. If frequency
counter does not indicate between 14.271 and 14.300 ms, perform b (2) below.
(11) Set SW-7 switch to OFF.
(1) Adjust CALIB. POT NO. 1 for zero indication on GALVO-2 (R).
adjust CALIB. POT NO. 2 for zero indication on GALVO-2 (R).
