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.

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.
