OVERVIEW

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 specications before us-

ing the Meter.

MIE0141/MIE0142 multimeter is a hand-held 3 1/2 digital display

digital multimeters with advanced design, multiple entire functions,

novel gurations and reliable performance. This meter is fully ca-

pable to measure voltage both AC and DC, DC current, resistance,

inductance, temperature and forward voltage drop of diode, tran-

sistor, hFE and continuity test etc. Please use multi-purpose socket

to measure SMT as well. This operating manual covers information

on safety and cautions to fulll CE mark standard. 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.

RULES FOR SAFE OPERATION

Owner’s manual

● Do not apply more than the rated voltage, as marked on the

Meter.

● When measurement has been completed, disconnect the con-

nection between the test leads and the circuit under test and turn

the Meter power off.

● The rotary switch should be placed in the right position and no

any changeover of range shall be made during measurement is

conducted to prevent damage of the Meter.

● Do not carry out the measurement when the Meter’s back case

and battery compartment are not closed to avoid electric shock.

● When the Meter working at an effective voltage over 60V in DC

or 30V rms in AC, special care should be taken for there is danger

of electric shock.

● Use the proper terminals, function, and range for your measure-

ments.

● Do not use or store the Meter in an environment of high tempera-

ture, humidity, explosive, inammable and strong magnetic eld.

The performance of the Meter may deteriorate after dampened.

● When using the test leads, keep your ngers behind the nger

guards.

● Disconnect circuit power and discharge all high-voltage capaci-

tors before testing resistance, continuity and diode.

● 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 servicing the Meter, use only the same model number or

identical electrical specications replacement parts.

Owner’s manual

● 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.

● The Meter is suitable for indoor use.

● Turn the Meter off when it is not in use and take out the battery

when not using for a long time.

● Constantly check the battery as it may leak when it has been us-

ing for some time, replace the battery as soon as leaking appears.

A leaking battery will damage the Meter.

MEASUREMENT OPERATION

First check on 9V battery, then turn rotary switch to the measur-

ing position. lf the low battery, sign will be displayed on LCD

panel. Nearly to sign on the meter front panel terminal input

which alarm not exceed the testing voltage and current input value

limitation.

I. DC or AC voltage measurement (see diagram 2)

1) Turn rotary switch to V~ or V voltage measurement.

2) Insert the red test lead into the “V” terminal and the black test

lead into the “COM” terminal, connect the lest leads across with the

object being measured. The measured value shows on the display

AC voltage measurement shows on true root mean square value

stability period.

3) In each range, the meter has an input impedance of 10M . V~

input impedance is about 4.5M . This loading effect can cause

measurement errors in high impedance circuits. If the circuit im-

pedance is less than or equal to 10k , the error is negligible (0.1%

or less).

Warning:

• To avoid possibly damages to the meter, please do not at-

tempt to input higher than 600V.

• To avoid electrical shock, please pay attention during the

high voltage measurement.

Owner’s manual

II. DC current measurement (see diagram 3)

1) Turn rotary switch to A current measurement.

2) Insert the red test lead into the „ mA” or ”10A” terminal, and the

black test lead into the „COM” terminal, Connect the test leads

across with the object being measured. The measured value

shows on the display.

Warning:

• Pre-requisites: Turn off power to the circuit before the con-

nection between the test leads across with the object being

measured.

• Selecting the correct terminal input and turn the rotary

switch to select the measuring function. In case of no any idea

on the value input of the current, just simply test from the high

value to low one.

Diagram 2

Owner’s manual

• Fuses are located on mA and 10A terminal input.

Never attempt the test lead connect to any circuits especially

on the power supply terminal and may be hurt.

• For the safety purpose, less than 10 seconds is for each

measurement duration and keep 15 minutes duration for next

measurement during the current measurement over 5A.

Diagram 3

Owner’s manual

Warning:

• The LCD displays „1” indicating open-circuit for the tested

resistor or the resistor value is higher than the maximum

range of the meter.

• To maintain the resistance measurement accuracy, discount

circuit power and discharge all the high voltage capacitors

during the measuring resistance.

• For high-resistance measurement greater than 1M , it is

normal to take several seconds to obtain a stable reading with

short test leads for measurement.

• Do not input higher than DC 60V and AC 30V voltage to pre-

vent any damage and accident.

III. Resistance measurement (see diagram 4)

1)Turn rotary switch to “ ” ohm measurement.

2) Insert the red test lead into the “ ” terminal and the black test

lead into the “COM” terminal. Connect the test leads across with

the object being measured. The measured value shows on the

display.
