(10) Monitor dc voltage at TP2 with a digital multimeter using the cage as the
ground reference.
(11) Adjust R1 so that the voltage at TP2 is about 2.5 V (this voltage is unstable and
just between the high and low crossover points) (R).
(12) Press the RESET pushbutton and disconnect resistance standard No. 2.
(13) Set FUNCTION switch to IR (0.1M).
(14) Set AUTO/SINGLE switch to SINGLE.
(15) Press the ADVANCE pushbutton once; the TEST light should be on and the
FAULT light should be off.
(16) Set resistance standard No. 2 for 100 kΩ and connect between pins 1A and 1B
(fig. 1) of the
electric connector assembly (connected to
end of
adapter cable).
(17) Use digital multimeter to measure dc voltage at TP1, with the cage as ground
reference. The voltage should be about 900 mV.
(18) Monitor the dc voltage reading at TP3; if it is different from that at TP1, adjust
R3 so that voltage at TP3 is the same (1 mV) as that at TP1 (R).
(19) Press the RESET pushbutton and disconnect resistance standard No. 2.
(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 MΩ and connect between pins 1A and
1B (fig. 1) of the electric connector assembly (connected to end of adapter cable).
(24) Use digital 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 8a above (and 9a and 10a below, if applicable).
