GENERAL DESCRIPTION
The Cablescan Model QS-200S provides a versatile method of identifying and terminating cable and
harness assemblies. Its use eliminates the need for color-coding, number stamping or tagging, and
'ringing out' with buzzers or ohmmeters. This production identification tool has the ability to rapidly
search wires using the operator's fingertips. It permits high-speed identification and selection of wires or
termination points for rapid, error-free assembly. A three-digit LED numerical display, universally
applicable to any present assembly method, is used in place of existing color, letter, or alphanumeric
designations.
The QS-200S is a compact, self-contained instrument, using body conductance to allow unmatched
versatility in identifying any wire at random. Two hundred signal inputs are provided on four connectors
of 50 pins each. Contact of the probe output to any input will produce a three-digit display of the number
assigned to that particular input. An adapter cable, which matches assembly numbers to the
corresponding QS-200S inputs, connects to the cable or harness assembly.
The operator wears a wrist strap, which provides an infinitesimal signal through a lead wire connected to
the probe output jack. This allows the human hand to function as a probe. By touching the stripped or
unstripped wire-end at random, wire identity is instantly determined.

QS-200S Instruction Manual Page 1
INSTALLATION
Each QS-200S has been inspected prior to shipment and should meet the electrical specifications and be
mechanically free from dents or scratches. To confirm this, carefully remove the instrument from the
shipping container and inspect for shipping damage or other deficiencies. If damage or deficiencies are
apparent, please contact the local sales representative or factory for assistance.
POWER REQUIREMENTS
The QS-200S operates on line voltages of 104-126 and 208-252 V~, 50-60 Hz. A label on the back panel
indicates the correct voltage for the unit.
CAUTION:
To avoid instrument damage, the power transformer must be wired correctly
before applying line power; i.e., connecting the power cord. To operate the
instrument at a different line voltage, a transformer connection change is
required. After alteration, note the proper line voltage on the back panel label.
WARNING:
When the power line cord is connected, the line voltage may be present on the
power input connector and input power transformer terminals, irrespective of the
circuit breaker switch position. Contact with these points may result in personal
injury or death. Therefore, always disconnect the power cord when changing
power transformer connections.
For the purpose of changing transformer line voltages, perform the following steps to expose the power
transformer:
a. Loosen side knobs and remove handle/positioner.
b. Place instrument upside down and remove four screws securing the bottom dust cover.
Removal of the bottom cover exposes the line transformer mounted on the rear panel.
GROUNDING REQUIREMENTS
For the personal safety of the operator and proper instrument operation, a provision for grounding the
instrument case has been provided. The offset pin of the power cable grounds the instrument when
plugged into the appropriate receptacle. THE INSTRUMENT WILL NOT OPERATE RELIABLY
UNLESS PROPERLY GROUNDED.
INSTRUMENT POSITIONING
The front of the QS-200S may be adjusted in elevation for operating convenience. Loosen the two side
knobs, adjust the handle/positioner for the desired position, and then firmly tighten the side knobs.
REPAIR
If the instrument is to be shipped to Cablescan for service or repair, enclose a note with the instrument
describing the malfunction and identifying the person to contact if questions arise.

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.
