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 dened 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 dened

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 specically 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°.

Figure 1. Front Panel Range Selector

OHMS ADJ. knob

Function Selector

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 specically for use by trained and qualied 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 specic hazards to be avoided and are not implied to be sufcient 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 specic 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 qualied to recognize shock hazards and

trained in the safety precautions required to avoid possible injury.
