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.

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.

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.

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

- 3 -

high-voltage capacitors before testing

resistance, continuity, diodes or hFE.

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.

Remove the connection between the testing

leads and the circuit being tested, and turn the

Meter power off before opening the Meter

case.

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 power 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 using for some time,

replace the battery as soon as leaking appears.

A leaking battery will damage the Meter.

OPERATING INSTRUCTIONS

DC & AC VOLTAGE MEASUREMENT

1. Connect red test lead to “VΩmA” jack, Black

lead to “COM” jack.

2. Set RANGE switch to desired VOLTAGE

position, if the voltage to be measured is not

known beforehand, set switch to the highest

range and reduce it until satisfactory reading is

obtained.

3. Connect test leads to device or circuit being

measured.

4. Turn on power of the device or circuit being

measured voltage value will appear on Digital

Display along with the voltage polarity.

DC CURRENT MEASUREMENT

1. Connect red lead to “VΩmA”. and black lead to

“COM”

(for measurements between 200mA and

5A connect red lead to “5A” socket)

- 7-

2. Set RANGE switch to desired DCA position.

3. Open the circuit to be measured, and connect

test leads IN SERIES with the load in

with current isto measure.

4. Read current value on Digital Display.

5. Additionally, “5A”function is designed for

intermittent use only. Maximum contact time of

the test leads with the circuit is10 seconds,

with a minimum intermission time of 15

minutes between tests.

RESISTANCE MEASUREMENT

1. Connect red lead to “VΩmA”. Connect black

lead to “COM”.

2. Set RANGE switch to desired Ωposition.

3. If the resistance being measured isconnec-

ted to a circuit, turn offpower and discharge all

capacitors before measurement.

4. Connect test leads to circuit being measured.

5. Read resistance value on Digital Display.

DIODE MEASUREMENT

1. Connect red lead to “VΩmA”.Connect black

lead to “COM”.

2. Set RANGE switch to “ ”position.

3. Connect the red test lead tothe anode of the

diode to be measured and black test lead to

cathode.

4. The forward voltage drop in mV will be

displayed. Ifthe diode is reversed, figure “1”

will be shown.

- 8-

TRANSISTOR hFE MEASUREMENT

1. Set RANGE switch to the hFE position.

2. Determine whether the transistor is PNP of

NPN type and locate the Emitter, Base and

Collector leads. Insert the leads into the proper

holes of the hFE Socket.

3. The meter will display the approximate hFE

value at the condition of base current 10μA

and VCE2.8V.

AUDIBLE CONTINUITY TEST

1. Red lead to “VΩmA”, Black lead to “COM”.

2. RANGE switch to “ ” position.

3. Connect test leads to two points of circuit to

be tested. If the resistance is lower then 30Ω

±20Ω, the buzzer will sound.

BATTERY AND FUSE REPLACEMENT

Fuse rarely need replacement and blow almost

always as a result of operator error.

If “ ”appearsin display, itindicates that the

battery should be replaced.

To replace battery &Fuse (F500mA/250V for mA

terminal and F5A/250V for 5A terminal)remove

the 2 screws inthe bottom ofthe case, simply

remove the old, and replace with a new one. Be

careful to observe polarity.
