OPERATING CONTROLS & INDICATORS
(See Figure 1 for Front and Rear Panel layouts.)
POWER ON/OFF CIRCUIT
BREAKER: Depress to apply line power to unit.
MODE SELECT: Activates the QS-200S by placing the instrument in either the
ANALYZE, SCAN, or PRESELECT mode. A flickering
display in the SCAN Mode warns the operator of a multiple wire
input. ANALYZE extends dwell time on each wire allowing the
operator to identify multiple wires automatically. PRESELECT
allows selection of any one of the 200 inputs and will display
only when the preselected wire number has been activated by
the probe.
PROBE OUTPUT: A jack for connection of the wrist strap or a metallic probe.
PRESELECT SWITCHES: A set of three thumbwheel switches allows for the preselection
of any wire from 001 through 200.
DISPLAY:
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
wheel switches).
ADJUST KNOBS: Used to position the front panel for operating convenience.
SCAN INPUTS: 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.
TONE: A pulsating audio tone will sound when the preselected wire has
been activated by body conductance.
LINE POWER RECEPTACLE: Line power is applied here only after assuring proper line
voltage connection at the power transformer input.
