Function
Connects Test Set through accessory cables
to indicator under test.
Two rotary switches and a fine adjustment
knob to set capacitance value of simulated
PROBE in range of 0 to 8000 pF.
Rotary switch selects the simulated
PROBE capacitance value in increments
of approximately 1000 pF from 0 to 7000
pF .
Rotary switch selects the simu-
lated PROBE capacitance value in incre-
ments of approximately 200 pF from 0 to
800 pF .
This fine adjustment control sets the simulated
PROBE capacitance value in the range of
15 to 390 pF.
