Measurement Operation

Before measurement, anticlockwise circumgyrate the

red cover and rock the input terminal.

When all themeasurement has been completed,

deasil circumgyrate the red cover then hide the input

terminal. (see ﬁgure 3)

1. AC / DC Voltage auto Measurement.

Warning

To avoid harm to the Meter, never input higher than

300V voltage although it is possible to measure

higher voltage.

To measure Voltage, connect the Meter as follows:

● Set the switch to V .

● Auto measuremeng mode is a default. Under this

mode can measure AC voltage and DC voltage.

● Connect the test leads across with the object

being measured. The measured value shows on

the display.

● When voltage measurement has been completed,

disconnect the connection between the testing

leads and the circuit under test, and remove the

testing leads away from the input terminal of the

meter.

Note:

The threshold voltage of AC voltage is around 400mV.

2. DC Voltage Measurement

Warning

To avoid harm to the Meter, never input higher than

300V voltage although it is possible to measure

higher voltage.

● Set the switch to V .

● Press SELECT to select DC voltage measurement

mode.

● Connect the test leads across with the object

being measured. The measured value shows on

the display.

● When voltage measurement has been completed,

disconnect the connection between the testing

leads and the circuit under test, and remove the

testing leads away from the input terminal of the

meter.

Operating Manual

Overview

This Operating Manual covers information on safety

and cautions. read the relevant information Please

carefully and observe all the Warnings and Notes

strictly.

Warning

To avoid electric shock or personal y, read the injur

"S Information Safety " and "Rules for afe Operation"

carefully before using the Meter.

The Model UT118A and UT118B (hereafter referred

to as the Met are counts pen type digits “ er”) 3000

millimeters. The Meter uses large scale of integrated

circuit with professional multimeter as its core and IC

has full range overload protection.

The Meter measures or tests the following:

● AC/DC voltage

● EF Function (UT118B only)

● Resistance

● Diode

● Continuity

● Capacitance

Unpacking Inspection

Open the package case and take out the Meter.

Check the following items carefully to see any

missing or damaged part:

Item Description Qty

2 Test Lead 1 pair

In ﬁnd the event you any missing or damage, please

contact your dealer immediately.

Safety Information

This Meter complies with standards in EN61010:

pollution degree over voltage category (CA2, TIII

300V) and double insulation.

CAT : Distribution level, fi ed installation, with III x

smaller transient over voltages than CAT V. I

Use the Meter only as specified in this operating

manual, otherwise the protection provided by the

Meter may be impaired.

In this manual, a Warning identifies conditions

and actions that pose hazards to the user, or may

damage the Meter or the equipment under test.

A Note the information that user should pay identiﬁes

attention on.

Rules For Safe Operation

Warning

To avoid possible electric shock or personal y, injur

and to avoid possible damage to the Meter or to the

equipment under test, adhere to the following rules:

● Before using the Meter inspect the case. Do not

use the Meter if it is damaged or the case (or part

of the cas is removed. k for cracks or missing e) Loo

plastic. ay attention to the insulation around the P

connectors.

● Inspect the test leads for damaged insulation or

exposed metal. Check the test leads for continuity.

Replace damaged test leads with identical model

number or electrical specifications before using the

Meter.

● When using the test leads, keep your fingers

behind the ﬁnger guards.

● Do not apply

more than the rated voltage, as

marked on the Meter, between the terminals or

between any terminal and grounding.

● When the Meter working at an effective voltage

over V DC or V AC, special care should be 60 30

taken for there is danger of electric shock.

● Use the proper function, and range for your

measurements.

● Disconnect circuit power and discharge all high

voltage capacitors before testing current, resistance,

diodes or continuity.

● Replace the battery as soon as the battery

indicator appears. With a low battery, the Meter

might produce false readings that can lead to electric

shock and personal injury.

● When servic ing t he Met er, use only the

same model or identical electrical specifications

replacement parts.

● The internal circuit of the Meter shall not be

altered at will to avoid damage of the Meter and any

accident.

● S oft cloth and mild detergent should be used to

clean the surface of the Meter when servicing

. No

abrasive and solvent should be used to prevent the

surface of the Meter from corrosion, damage and

accident.

● Do not use or store the Meter in an environment

of high temperature, humidity, explosive, inﬂammable

and strong magnetic field. The performance of the

Meter may deteriorate after dampened.
