INSTRUMENT DESCRIPTION

SECTION 1

INSTRUMENT DESCRIPTION

INTRODUCTION

The Model 110A Safety Voltmeter is the only single switch,

single range, digital voltmeter that automatically measures

AC & DC volts to 1000 V for voltage troubleshooting, line

clearing, lock out/tag out procedures and anywhere

hazardous voltages may be present. The 110A has a 1 MΩ

current limiting resistor in each lead to protect the user

against arc-flash potential.

Model 110A meets Category IV 600 V and Category III 1000

V Overvoltage protection under IEC-61010-1.

accuracy specifications. Below 64 °F and above 82 °F; less than

0.05 times applicable specifications per °F.

LOW-BATTERY INDICATOR: Display indicates ‘BAT’ when less

than 10% of life remains.

AUTOMATIC TURN-OFF: Voltmeter turns off after 10 minutes of

operation. Turns off below 6.5 V battery voltage.

SIZE: 6.3” x 2.7” x 1.2”

WEIGHT: 12 oz.

INSTRUMENT DESCRIPTION

1104 - Leather Utility Belt Carrying Case

The 1104 case protects your voltmeter and probes from broken

displays and other damages that can occur. This case has a 2 in. belt

loop. It is long lasting, super durable, and is made from top-grain

cowhide with riveted seams.

1204 - Cordura Nylon lineman’s Carrying Case

The 1204 case protects your voltmeter and saves you time because the

meter can stay in the case during use. It features a window to access

the ON/OFF switch, a retainer that holds the meter in place, space for

probe storage and a 22 in. shoulder strap. It also comes with a belt clip

and can be worn on a utility belt. Size- 5 ½ x 7 ½x 1 ½ in. (W x H x

D).

INSTRUMENT DESCRIPTION

12501 - Alligator Clip Adapter

The 12501 probe adapter kit allows you to convert your test leads to

alligator clips. The kit includes two screw-on probe adapters and two

heavy duty screw in alligator clips with insulating rubber boots. These

alligator clips open to ½ in. and fit most terminals and bus bars.

12502 - Universal Adapter Kit

The 12502 probe adapter kit includes two screw-on probe adapters and

interchangeable screw-in accessories including two alligator clips with

insulating rubber boots, two banana plugs, two needle tips, two spade

lugs and two heavy duty tips. With this kit you can adapt your

voltmeter to the many different situations you encounter on the job.

PREPARATION FOR USE

SECTION 2

PREPARATION FOR USE

UNPACKING AND INSPECTION

Each instrument is inspected both mechanically and electrically

before shipment. Upon receiving your instrument unpack all items

from the shipping container and check for any obvious damage that

may have occurred during transit. Report any damage to the

shipping agent. Retain and use the original packing materials if

reshipment is necessary.

PREPARATION FOR USE

Each instrument is supplied with a 9 V battery. See page 3-8 of this

manual for battery installation instructions.

OPERATION

The Model 110A digital voltmeter (DVM) is easy to use. There is

only one control (located on the side of the instrument) that turns

the instrument ON/OFF (Figure 1).

After turn-on, the instrument automatically selects either VDC or

VAC function. VDC is selected if the magnitude of a DC input

voltage is greater than the peak value of any AC voltage present.

Otherwise the VAC function is enabled. VAC and VDC annunciators

in the liquid crystal display indicate the selected function. Observe

the maximum allowable input (1000 V continuous).

After approximately 10 minutes, the voltmeter turns off

automatically to conserve battery life. To turn the voltmeter on

PREPARATION FOR USE

again, return the ON/OFF switch to the OFF position, and then back

to the ON position.

When battery voltage drops below 6.5 V, the voltmeter turns off

until a new battery is installed (Refer to Battery Installation

Section).

OPERATING CONDITIONS

In accordance with the Standard for Electrical Measuring and Test

Equipment IEC-61010-1, the TEGAM Model 110A Safety Voltmeter

is designed for safe operation under the following conditions:

•Indoor use, or outdoor use in where the instrument and probes

remain dry (i.e. protected from exposure to rain, fluids, or

condensing humidity).

•Altitudes up to 2000 m above mean sea-level.

•Temperature: –23 °C to 65 °C

•Relative humidity: 80% R.H. up to 35 °C, decreasing linearly

to 0% R.H. at 60 °C.

•Power source: 9 V transistor battery (NEDA 1604), alkaline or

carbon-zinc type. The voltmeter automatically turns off before

battery discharge can cause malfunction.

•Pollution: Degree 2 per IEC 664.

•Installation Category IV (up to 600 V) / Category III (up to

1000 V)
