Rules For Safe Operation (1)
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:
l Before using the Meter inspect the case. Donot
use the Meter if it is damaged or the case (orpart
of the case) is removed. Look for cracks or
missing plastic. Pay attention to the insulation
around the connectors.
l 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.
l Do not apply more than the rated voltage, as
marked on the Meter, between the terminals or
between any terminal and grounding.
l 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.
l 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.
l Use the proper terminals, function, and range
for your measurements.
l 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.
l When using the test leads, keep your fingers
behind the finger guards.

Rules For Safe Operation (2)
l 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.
l 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.
l Do not apply more than the rated voltage, as
marked on the Meter, between the terminals or
between any terminal and grounding.
l 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.
l 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.
l Use the proper terminals, function, and range
for your measurements.
l If the value to be measured is unknown, use
the maximum measurement position.
l 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.
l When using the test leads, keep your fingers
behind the finger guards.
l Disconnect circuit power and discharge all high-
voltage capacitors before testing resistance,
continuity, diodes.

l Before measuring current, check the Meter’s
fuses and turn off power to the circuit before
connecting the Meter to the circuit.
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 When servicing the Meter, use only the same
model number or identical electrical specifications
replacement parts.
l The internal circuit of the Meter shall not be altered
at will to avoid damage of the Meter and any accident.
l 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.
l The Meter is suitable for indoor use.
l Turn the Meter off when it is not in use and take
out the battery when not using for a long time.
l 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.

Measurement Operation(1)
A. DC Voltage Measurement (see figure 3)
( figure 3)
Warning
To avoid harms to you or damages to the Meter from
eletric shock, please do not attempt to measure
voltages higher than 1000V, although readings may
be obtained.
Note
l The Meter has an input impedance of 10M This
can cause measurement errors in high impedance
circuits. If the circuit impedance is less than or equal
to 10k , the error is negligible (0.1% or less).
l Special care should be taken when measuring high
voltage.
l When DC 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.
The DC Voltage ranges are: 4V, 40V, 400V and 1000V;
To measure DC voltage, connect the Meter as follows:
1. Insert the red test lead into the Vterminal and the
black test lead into the COM terminal.
2. Set the rotary switch to V ;press SELECT button
to select DC measurement mode.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.

C. DC Current Measurement (see figure 4)
( figure 4)
Warning
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 60V DC or 30V rms.
If the fuse burns out during measurement, the Meter
may be damaged or the operator himself may be hurt.
Use proper terminals, function, and range for the
measurement.
When the testing leads are connected to the current
terminals, do not parallel them across any circuit.
Before the Meter is connected in serial to the in-circuit
being tested, turn off the power of the in-circuit..

range step by step until a satisfactory reading is
obtained.
l When the measured current is 5A, continuous
measurement is allowed.
l When the measured current is between 5A-10A,
continuous measurement 10 seconds and interval

Measurement Operation(6)
E. Measuring Resistance (see figure 5)
Warning
To avoid harms to you, please do not attempt to input
voltage 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 measuring resistance.
(figure 5)
The resistance ranges are:400Ω, 4kΩ, 40kΩ,400kΩ,
4MΩand 40MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the Ω terminal and the
black test lead into the COM terminal.
2. Set the rotary switch to Ω ; Press SELECT
button to select Ω measurement mode.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
