This WARNING sign denotes a hazard. It calls attention
to a procedure, practice or the like, which if not correctly
performed or adhered to, could result in personal injury.
This instrument is designed to prevent accidental shock to operator when properly
used. However, no engineering design can render safe an instrument which is used
carelessely. Therefore, this manual must be read carefully and completely before
making any measurments. Failure to follow directions can result in serious or fatal
accident.
SHOCK HAZARD: As dened in IEC-1010-1 Safety Requirements for Electrical
Equipment for Measurement, Control and Laboratory Use, a shock hazard shall be
considered to exist at any part involving a potential in excess of 30 volts rms (sine wave) or
42.4 volts DC or peak where a leakage current from that part to ground exceeds 0.5 MIU
(Measurement Indication Units) when measured with an appropriate instrument as dened
in Section 6.3.1.2 Annex A of IEC-1010-1.

1. INTRODUCTION
The Simpson TS-113 Volt-Ohm-Milliammeter (hereafter referred to as the TS-113 or the
Instrument), is a rugged, reliable instrument which has been designed specically for
the widest possible range of electrical measurements associated with the RAILROAD
SIGNALING and COMMUNICATIONS eld. In construction and general principle it follows
closely the proven Simpson pattern which is based on the experience of many years of
successful multimeter manufacture.
Among its special features are provisions for:
Low insertion loss AC current measurements using an internal current transformer.
“ON” time measurement at any rate in excess of 30 pulses per minute.
An adjustable “Pointer Stop” which facilitates observation of “peak” readings of pulsating
voltage or current on coded track.
A current-limiting diode preventing meter movement overload beyond acceptable limits.
SUPPLIES AND ACCESSORIES
All supplies and accessories required to operate the TS-113 are supplied with the
Instrument and are listed in Table 1.

2. INSTALLATION
The following instructions explain the installation and shipping of the TS-113.
Included are unpacking and inspection procedures, warranty, shipping, power source
requirements and operating position.
UNPACKING AND INSPECTION
Examine the shipping carton for obvious signs of damage. If damage is noted, notify the
carrier and supplier and do not attempt further use of the instrument. If Instrument appears
to be in good condition, read Operator’s Manual in its entirety. Become familiar with the
Instrument as instructed in the manual, then proceed to check the electrical performance as
soon as possible. Also, check that all items are included with the instrument (Table 1).
After unpacking the Instrument, a 1.5 V battery and the 9V batteries (Qty. 2) may be found
in the box with the Instrument and test leads.
WARRANTY
The Simpson Electric Company warranty card is included with each instrument.
Read it carefully prior to requesting any warranty repairs.
NOTE: For assistance of any kind, contact your nearest Authorized Service Center, or visit
www.simpsonelectric.com for a list of Service Centers.

SHIPPING
Pack the Instrument carefully and ship it prepaid and insured to the proper destination.
CONTROLS, JACKS AND INDICATORS
All operating and adjustment controls, jacks and indicator for the TS-113 are described in
the following pages. Become familiar with each item prior to operating the Instrument.
Notes:

FRONT PANEL DESCRIPTION
The Instrument’s highly legible markings are designed for easy, accurate readings. The
4” red knife-edge pointer and scale mirror, permit improved resolution of readings and
elimination of parallax errors.
The dial itself is color coded to match the range and function switch for ease of
interpretation.
In the lower center of the meter cover is the adjustable pointer stop. The knob is used in
peak reading determination. Travel is limited in both directions. The zero adjuster below it,
rotates freely through 360°.
Six jacks provide connections for all the twenty seven direct reading ranges. Twenty one of
these ranges are served by the “+” and “–” connections in the lower left corner of the panel,
the remainder by the “AMP” connection and one of the two jacks( 6A or 30A) on the right
hand side, and the 600V jack.
The center knob rotates the range switch smoothly through a full 360°.

The panel is marked and color coded to permit easy and accurate selection of any of its
positions. There is a “Transit” position for vibration protection during travel, and a blank
position between ohms and mA to protect against accidentally switching between ranges.
The left knob rotates between 3 positions -DC, DC and AC.
Precise, gradual adjustment of zero ohms is made possible by the right hand knob . This
control is also used to set the 100% reading for “ON” time measurements, when used
together with the “Push to Set” switch. With the button depressed the right hand knob now
adjusts the “ON” time full scale.
REPLACEABLE COMPONENTS
A 1.5 V size D battery powers all resistance-measuring ranges. The low battery voltage is
aimed at preventing the accidental tripping of relays during the measurement of relay circuit
resistance.
One 9.0 volt Alkaline battery powers the “ON” time measuring circuit. Other 9.0 volt alkaline
powers the Rx 1K circuit.
The glass fuse unclips for fuse replacement.
Note: The rear case must be removed to replace the cartridge fuse. No other components
are replaceable or serviceable by the user.

3. SAFETY PRECAUTIONS
This section of the manual contains information required to use and operate the TS-113 in a
safe and proper manner.
The TS-113 has been designed specically for use by trained and qualied personnel
working on railway signaling and communications systems. It is not intended to make
measurements in heavy-duty railway equipment such as diesel-electric locomotives, railway
cranes or the like. Its ranges, however, are capable of making measurements in circuits in
which the available energy levels can produce dangerous arcing and explosive forces if
accidentally short-circuited.
Whenever working on such circuits, the operator must take care to assure that the
meter and its test leads are in good working condition, that the circuit cannot become
unexpectedly shorted, that the meter controls are properly set and test leads correctly
connected, and that all safety precautions are observed at all times.
The following precautions are suggestions and reminders of commonly recognized safe
practices and specic hazards to be avoided and are not implied to be sufcient to ensure
the safety of untrained personnel in all circumstances. Neither is the manual a substitute for
technical manuals covering the equipment in which measurements are to be made. Always
refer to the equipment service manual and its specic warnings and instructions and
observe them as well as those contained herein. Unusual measurements under unusual
conditions may require additional precautions and safety measures.
The TS-113 should only be used by personnel qualied to recognize shock hazards and
trained in the safety precautions required to avoid possible injury.
