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 gure 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. Please read the relevant information

carefully and observe all the Warnings and Notes

strictly.

Warning

To avoid electric shock or personal injury, read the

"Safety Information" and "Rules for Safe Operation"

carefully before using the Meter.

The Model UT118A and UT118B (hereafter referred

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

millimeters. The Meter uses large scale of integrated

circuit with professional multimeter IC as its core and

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 ite ms carefully to see any

missing or damaged part:

Item Description Qty

1 English Operating Manual 1 piece

2 Test Lead 1 pair

In the event you nd any missing or damage, please

contact your dealer immediately.

Safety Information

This Meter complies with standards EN61010: in

pollution degree 2, over voltage category (CATIII

300V) and double insulation.

CATIII: Distribution level, fixed installation, with

smaller transient over voltages than CAT IV.

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 ide ntifies con ditions

and actions that pose hazards to the user, or may

damage the Meter or the equipment under test.

A Note identies the information that user should pay

attention on.

Rules For Safe Operation

Warning

To avoid possible electric shock or personal injury,

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 case) is removed. Look for cracks or missing

plastic. Pay attention to the insulation around the

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 nger 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 60V DC or 30V AC, special care should be

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.

● Repl ace the b attery 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 ser vicing th e M e te r, u se only th e

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.

● Soft 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, inammable

and strong magnetic field. The performance of the

Meter may deteriorate after dampened.

2. HOLD

Press HOLD to enter and exit hold mode (except

under auto scan mode).

Press and hold the HOLD button more t han 2

seconds, the meter automatically holds the value

which obtains at 6 seconds later, at this time, is

displayed and ickering.

If enter “sleep” mode under hold mode, the meter still

in the hold mode when it be turned on.

3. MAX/MIN

The MAX /MIN mode stores minimum (MIN) and

maximum (MAX) input values (except under auto scan

mode). Manual ranging comes when you select this

function.

Press button MAX MIN MAX/MIN MAX/MIN

and vice versa.

Under hold mode and max/min mode, should exit hold

mode rst then press and hold MAX/MIN more than 1

second to exit max/min mode.

Display Backlight and test lead light button, Press

once to turn the display backlight and test lead light

on and press again to turn the display backlight and

test lead light off. It will automatically off after around

1 minute.

5. AUTO POWER OFF

To preserve battery life, the Meter automatically goes

into a “sleep” mode if you do not press any button for

around 10 minutes. The Meter can be activated by

pressing any button, then returns to the display for the

function selected previously

6. BUZZER

The buzzer phonate go with every time button be

effectual pressed. When the meter will auto power off

in 20 seconds the buzzer beeps three times. Before

power off there will be a long time buzzer beeps.
