(20) Set FUNCTION switch to IR (10M).
(21) Set AUTO/SINGLE switch to SINGLE.
(22) Press the ADVANCE pushbutton once; the TEST light should be on and the
FAULT light should be off.
(23) Connect resistance standard No. 3 for 10 M and connect between pins 1A and
1B (fig. 1) of the electric connector assembly (connected to end of adapter cable).
(24) Use the multimeter to measure dc voltage at TP1, with the cage as ground
reference. The voltage should be about 360 mV; take the exact reading.
(25) Take the voltage reading at TP3. If it is different from that at TP1, adjust R2 so
that voltage at TP3 is the same ( 1 mV) as that at TP1 (R).
(26) Press the RESET pushbutton and disconnect resistance standard No. 3.
(27) Repeat 8 a above (and 9 a and 10 a below, if applicable).

(8) Press the RESET pushbutton and disconnect resistance standard No. 2.
b. Adjustments. Perform 8 b above, if not previously performed. Otherwise, no other
adjustments can be made.
10. Insulation Resistance (10 M )
a. Performance Check
(1) Set FUNCTION switch to IR (10M).
(2) Set AUTO/SINGLE switch to SINGLE.
(3) Press the RESET pushbutton.
(4) Connect resistance standard No. 3 in series with resistance standard No. 2 and
set for a total resistance value of 10.3 M .
(5) Press the ADVANCE pushbutton once to test circuit A01. TI TEST light will be
on and the FAULT light will remain off; if not, perform b below.
