only when the preselected wire number has been activated by
the probe.
A jack for connection of the wrist strap or a metallic probe.
A set of three thumbwheel switches allows for the preselection
of any wire from 001 through 200.
A three-digit visual readout of the corresponding pin on scan
inputs connected to PROBE.
Note:
Decimal point to the right of the units display indicates
operation in the ANALYZE mode. Decimal point to the right of
the hundreds display indicates a wire probed in the
PRESELECT mode (other than the wire selected by the thumb

Four connectors J1 (1-50), J2 (51-100), J3 (101-150), J4 (151-
200), are inputs to the QS-200S for the cable or harness being
identified.
A pulsating audio tone will sound when the preselected wire has
been activated by body conductance.
Line power is applied here only after assuring proper line
voltage connection at the power transformer input.
