If Indication abnormal
34.8 K Ω.+ 10%
With the digital multimeter set to measure res-
istance, measure the resistance between the two test
points labeled R1 on the test fixture.
9090 Ω +o10%
Using the digital multimeter, measure the res-
istance between the two test points labeled R2 on the
While observing the digital multimeter, measure the
Continuously variable from 0
to 50 KΩ + 10%
resistance between test points R3-1-2 and R3-3 on
the test fixture while adjusting R3 on the UUT
through its entire range.
Set the digital multimeter to measure dc voltage
and connect between the test points +30 and GND
on the test fixture.
Verify that the power supply is off and turn the
VOLTAGE adjust control fully counterclockwise
Connect the power supply to the test fixture as
Turn the powersupply switch to ON. Turn the
VOLTAGE adjust control clockwise until +30
+0.5V is indicated on the digital multimeter.
Set the RELAY SEL switch to the 2 position
and readjust the power supply, if necessary. Connect
SW and J 1-8 on the test fixture.
Set the RELAY SEL switch to the 1 position
Check CR1, R4, and R5.
