(9) Repeat technique of (4) through (7) above for each setting of RESISTANCE
CHECK SW-3 switch and set resistance standard to the value indicated on SW-3. TI
GALVO-1 will indicate within 5 divisions at all SW-3 settings.
b. Adjustments.
Adjust RES CHECK
TRIMPOT (fig. 2)
for 0 indication on
GALVO-1 (R).
10. Insulation
Resistance Check
a. Performance Check
(1) Adjust resistance standard for 0 ohms.
(2) Connect TI INPUT RES. INSUL. P-2 to HIGH and LOW terminals of
resistance standard using cables and insulation check adapter (BH485 and BH821, p/o TI).
(3) Set SELECTOR SWITCH SW-1 to INSUL. and SW-8 switch to RX100. If
INSULATION CHECK meter does not indicate 0, perform b (1) below.
(4) Adjust resistance standard for indication of 10,000 ohms on INSULATION
CHECK meter. If resistance standard does not indicate between 9000 and 11,000 ohms,
perform b (2) below.
