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.

Do not apply more than the rated voltage, as marked

on the Meter, between the terminals or between any

terminal and grounding.

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.

Model UT71A/B/C/D/E: OPERATING MANUAL

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 measurements.

If the value to be measured is unknown, use the

maximum measurement position.

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.

When using the test leads, keep your fingers behind

the finger guards.

Disconnect circuit power and discharge all high-

voltage capacitors before testing resistance,

continuity, diodes.

Before measuring current, check the Meter's fuses

and turn off power to the circuit before connecting

the Meter to the circuit.

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 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.

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.

Getting Acquainted

Turning the Meter On

To turn the Meter on, turn the rotary switch from OFF

to any switch setting.

Battery Considerations

The Meter uses one 9V Battery (NEDA 1604, 6F22,

006P). The following paragraphs describe several

techniques used to conserve battery power.

Automatic Power Off

The display blanks and the Meter goes into a "sleep"

mode if you have not changed the rotary switch position

or pressed a button for a set period. While in Sleep

mode, pressing the blue button or turning the rotary

switch could turn the Meter on. The Meter then returns

to the display for the function selected with the rotary

switch; all previously activated button features are

discarded.

Automatic Backlight Off

Press LIGHT button to turn the backlight on and press

LIGHT again to turn it off. Press EXIT to exit the feature.

Press LIGHT to select the backlight level (low or high).

In Setup menu (see Chapter 5), you could specify a

time to automatically turn off the backlight (10 seconds,

20 seconds, 30 seconds or OFF). If the period is set

to OFF, the backlight feature is disabled.

The automatic power off is preset to 10 minutes. From

the Setup menu (see Chapter 5), you could specify a

time (10 minutes, 20 minutes, 30 minutes or OFF). If

you set to OFF, the Meter retains on until you turn the

rotary switch to OFF or the battery becomes too weak.

Model UT71A/B/C/D/E: OPERATING MANUAL

Low Battery Indication

A constant battery icon ( ) in the upper left corner of

the display notifies you that the batteries are low and

should be replaced.

Warning

To avoid false readings, which could lead to possible

electric shock or personal injury, replace the battery as

soon as the battery icon ( ) appears.

Making Measurement

Introduction

Chapter 3 explains how to make measurements. Most

measurement functions can be selected by using the

rotary switch.

While letters or symbols identify primary functions; blue

letters or symbols identify alternative functions. Press

the BLUE button to access these alternate functions.

A. Measuring Voltages

Warning

To avoid harms to you or damages to the Meter

from electric shock, please do not attempt to

measure voltages higher than 1000V, although

readings may be obtained.

To measure voltages, set up the Meter as Figure 3-1

and do the following:

Figure 3-1. Voltages Measurement

Model UT71A/B/C/D/E: OPERATING MANUAL

Insert the red test lead into the V terminal and the

black test lead into the COM terminal.

Set the rotary switch to or or ;

Set the rotary switch to or or (UT71E).

The default is DC voltage measurement, press BLUE

button to switch to AC voltage measurement mode.

Connect the test leads across with the object being

measured.

The measured value shows on the display.

AC measurement displays the True RMS value.

DC measurement displays the effective value of sine

wave (mean value response).

When a ACV function is selected, you can press the

Yellow Button to view the AC + DC True RMS value

in the primary display. To exit, please EXIT button.

The BLUE button cycles among , frequency and

duty cycle.

Note

When measuring voltage, the Meter acts around a

10M ( and ) or 2.5G ( ) impedance in

parallel with the circuit. This loading effect can cause

measurement errors in high impedance circuits. In

most cases, the error is negligible (0.1% or less) if

the circuit impedance is 10k or less.

Special care should be taken when measuring high

voltage.

When voltage measurement has been completed,

disconnect the connection between the testing leads

and the circuit under test and remove testing leads

away from the input terminals of the Meter.

Model UT71A/B/C/D/E: OPERATING MANUAL

B. Measuring Currents

Warning

If the fuse burns out during measurement, the Meter

may be damaged or the operator himself may be hurt.

To avoid possible damage to the Meter or to the

equipment under test, check the Meter's fuses before

measuring current. Use proper terminals, function,

and range for the measurement. Never place the

testing leads in parallel with any circuit or component

when the leads are plugged into the current terminals.

Warning

To avoid harms to you, please do not attempt to input

voltage higher than 60V DC or 30V rms AC.

To avoid possible damages to the Meter or to the

devices under test, disconnect circuit power and

discharge all the high-voltage capacitors before

measuring continuity.

To test for continuity, set up the Meter as Figure 3-4

and do the following:

Insert the red test lead into the terminal and the

black test lead into the COM terminal.

Set the rotary switch to ; press BLUE button

to select measurement mode and connet the

test leads across with the object being tested.

The beeper comes on continuously for open

conditions, that is test resistance 50 .

The BLUE button cycles among resistance, continuity,

and diode.

Note

When measuring low resistance, the test leads can

add 0.1 to 0.2 of error to resistance measurement.

To test the leads, touch the probe tips together and

read the resistance of the leads. If necessary, you

can press REL to automatically subtract this value.

For high-resistance measurement (>1M ), it is normal

taking several seconds to obtain a stable reading.

In order to obtain precision readings, use the test

lead as short as possible.

The LCD displays OL indicating open-circuit or the

tested resistor value is higher than the maximum

range of the Meter.

When testing the resistance signal from the calibrator,

it is necessary to press and hold the RANGE while

turning on the Meter to change the maximum display

to 4000 counts but the accuracy remains unchanged.

When resistance measurement has been completed,

disconnect the connection between the testing leads

and the circuit under test and remove testing leads

away from the input terminals.

Model UT71A/B/C/D/E: OPERATING MANUAL

Figure 3-4. Continuity Test

Note

Open circuit voltage around -1.2V and range is 400

measurement range.

When continuity testing has been completed,

disconnect the connection between the testing leads

and the circuit under test and remove the test leads

away from the input terminals.

Model UT71A/B/C/D/E: OPERATING MANUAL

E. Testing Diodes

Figure 3-5. Diode Test

Warning

To avoid harms to you, please do not attempt to input

voltages higher than 60V DC or 30V rms AC.

To avoid damages to the Meter or to the devices under

test, disconnect circuit power and discharge all the

high-voltage capacitors before testing diodes.

Use the diode test to check diodes, transistors, and

other semiconductor devices. The diode test sends a

current through the semicondutor junction, then measure

the voltage drop across the junction. A good silicon

junction drops between 0.5V and 0.8V

To test the diode out of a circuit, set up the Meter as

Figure 3-5 and proceed as follows:

Insert the red test lead into the terminal and the

black test lead into the COM terminal.

Set the rotary switch to ; and press BLUE

button to select measurement mode.

Model UT71A/B/C/D/E: OPERATING MANUAL

For forward voltage drop readings on any

semiconductor component, place the red test lead on

the component's anode and place the black test lead

on the component's cathode. The red test lead polarity

is "+" while the black test lead polarity is "- ".

The measured value shows on the display.

The BLUE button cycles among resistance, continuity,

and diode.

Note

In a circuit, a good diode should still produce a

forward voltage drop reading of 0.5V to 0.8V; however,

the reverse voltage drop reading can vary depending

on the resistance of other pathways between the

probe tips.

Connect the test leads to the proper terminals as

said above to avoid error display.

The LCD will display OL indicating either open circuit

or wrong polarity connection.

The unit of diode is volt (V), displaying the positive-

connection voltage-drop value.

Open circuit voltage approximate 2.8V.

l When diode testing has been completed, disconnect

the connection between the testing leads and the

circuit under test and remove the test leads away

from the input terminals.

Model UT71A/B/C/D/E: OPERATING MANUAL

F. Measuring Capacitance

Figure 3-6. Capacitance Measurement

Warning

To ensure accuracy, the Meter inside is discharged

against the tested capacitor. "DIS.C" will be shown

on the display when it is under discharging, this

process will be quite slow.

To avoid damage to the Meter or to the equipment

under test, disconnect circuit power and discharge

all high-voltage capacitors before measuring

capacitance.

Use the DC Voltage function to confirm that the capacitor

is discharged.

To measure capacitance, set up the Meter as shown

in Figure 3-6 and proceed as follows:

Insert the red test lead into the terminal and

the black test lead into the COM terminal.

Model UT71A/B/C/D/E: OPERATING MANUAL

Set the rotary switch to measurement mode,

the Meter may display a fixed reading which is a

internal distributed capacitor value. For testing less

than 10nF capacitor, the tested value must subtract

the internal distributed capacitor value to maintain

the accuracy.

To improve the measurement accuracy of small value

capacitors (less than 10nF), press REL with the

test leads open to subtract the residual capacitance

of the Meter and leads.

It is recommended to use test clip to carry out

measurement to reduce the effect of internal

distributed capacitor.

Note

The LCD displays OL indicating the tested capacitor

is shorted or it exceeds the maximum range.

Capacitors larger than 400µF take longer time. The

analogue bar graph shows the time left before

finishing the measurement.

When capacitance measurement has been

completed, disconnect the connection between the

testing leads and the circuit under test and remove

the test leads away from the input terminals of the

Meter.
