Introduction

One kind of UNI-T brand new UT50 series

Multimeters is a 3 1/2 digit with steady function

and highly reliable hand-held measuring instrument.

The Meter uses large scale of integrated circuit

with double integrated A/D converter as its core

and has full range overload protection. The Meter

can measure DC current, AC current, DC Voltage,

AC Voltage, Resistance, Capacitance, Diode,

Temperature, Frequency and Continuity, which is

an ideal tool for users.

Model UT51-55: OPERATING MANUAL

Safety Rules

l Do not operate the Meter before the cabinet

has been closed and screwed safely as

terminal can carry voltage.

l Make sure before each measurement the

Meter is set to the suitable range.

l Before using the Meter, please inspect the

cabinet and test leads for damaged insulation

or exposed metal.

l Connect the red and black test lead to the

correct measuring input jack properly.

l Do not input values over the maximum

range of each measurement to avoid damages

of the Meter.

l The UNI-T UT50 series comply with

IEC 61010: in pollution degree 2,

overvoltage category (CAT I 1000V and

CAT II 600V) and double insulation.

Use the Meter only as specied in this

manual, otherwise the protection provided

by the Meter may be impaired.

l CAT I-For signal level, telecommunication,

electronic with small transient over voltage.

l CAT II -For local level, appliances, main

wall outlets, portable equipment.

l The meter is designed to withstand the

stated Max. voltages. If it’s not possible

to exclude without doubts that impulses,

transients, disturbance or for other reasons,

these voltages are exceeded a suitable

prescale (10:1) must be used.

l Do not turn the rotary function switch

during Voltage and Current measurement,

otherwise the Meter could be destroyed.

Model UT51-55: OPERATING MANUAL

l 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.

l Turn off the Meter once finished measuring,

fetch out the battery, when the meter will

not be used for long period.

l Do not operate the Meter under adverse

environmental condition especially humid

area.

l To avoid damages and dangerous, do not

change the circuit.

l Periodically wipe the case with a damp

cloth and mild detergent. Do not use

abrasives or solvents.

l International Electrical Symbols:

Low Battery Earth Ground

Safety Rules

Double Insulated

Diode

Dangerous Voltages

Buzzer

Fuse

l Make sure to use new fuses with proper

rating in stead of bad fuses .

l To avoid electric shock or damages, do

not apply more than 1000V between the

terminals and earth ground." " COM " "

l Use caution when working with Voltages

above 60V (DC) or 30Vrms (AC). These

Voltages pose shock hazard.

l The Meter is suitable for indoor use only.
