To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V though the reading may
be obtained.
The DC voltage ranges are: 8.0000V, 80.000V, 800.00V
and 1000.0V. To measure DC Voltage, connect the Meter
as follows:
When DC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing
leads away from the input terminals of the Meter.
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V though the reading may
be obtained.
The DC Millivolt ranges are: 80.000mV, 800.00mV. To
measure DC Voltage, connect the Meter as follows:
In this range, the Meter has an input impedance
higher than 4000MΩ
When DC mV voltage measurement has been
completed, disconnect the connection between
the testing leads and the circuit under test, and
remove the testing leads away from the input
terminals of the Meter.
D. Measuring Resistance / Conductance,
Capacitance & Continuity
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, capacitance & continuity. Use the DC
voltage function to confirm that the capacitor is
discharged.
Resistance / Conductance Measurement
(see figure 6)
The resistance ranges are: 800.00Ω, 8.0000kΩ,
80.000kΩ, 800.00kΩ, 8.0000MΩ, 80.000MΩ. To
measure the resistance, Conductance, connect the
Meter as follows:
1. Insert the red test lead into the terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to ; resistance
measurement is default.
3. Connect the test leads across with the object
being measured. The measured value shows on
the display.
Note
The test leads can add 0.1Ω to 0.2Ωof error to
resistance measurement. To obtain precision
readings in low-resistance measurement, that is the
range of 800.00Ω, short-circuit the input terminals
beforehand, using the relative measurement function
button REL to automatically subtract the value
measured when the testing leads are short-circuit
from the reading.
For high-resistance (higher than 1MΩ), it is normal
that it will take several seconds to obtain a stable
reading.
When measure resistance higher than 12.5MΩ,
conductance value can be displayed by pressing
HOLD. To switch to resistance value, press HOLD
again.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
When the resistance or conductance test has been
completed, disconnect the connection between the
testing leads and the circuit under test, and remove
the testing leads away from the input terminals of
the Meter.
Continuity Measurement (see figure 7)

To measure the continuity, connect the Meter as follows:
1. Insert the red test lead into the terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to and press to
select measurement mode.
3. The buzzer sounds if the resistance of a circuit under
test is less than 100Ω.
The LCD displays indicating the circuit being
tested is open.
Press while turning on the Meter to disable the
beeper of pressing any button.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
When continuity testing has been completed,
disconnect the connection between the testing leads
and the circuit under test. and remove the testing
leads away from the input terminals of the Meter.
E. Testing Diodes (see figure 9)
F. DC or AC Current Measurement (see figure 10)
Never attempt an in-circuit current measurement
where the open-circuit voltage between the circuit
and ground is greater than 600V.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.
Connect the test leads to the proper terminals as
said above to avoid error display.
The LCD will display indicating open-circuit for
wrong polarity connection.
The unit of diode is Volt (V), displaying the positive
-connection voltage-drop value.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
When diode testing has been completed, disconnect
the connection between the testing leads and the
circuit under test.
depending on the resistance of other pathways
between the probe tips.
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before measuring
diodes.
Use the diode test to check diodes, transistors, and other
semiconductor devices. The diode test sends a current
through the semiconductor junction, then measures the
voltage drop across the junction. A good silicon junction
drops between 0.5V and 0.8V.
To test a diode out of a circuit, connect the Meter as
follows:
1. Insert the red test lead into the terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to .
3. For forward voltage drop readings on any
semiconductor component, place the
terminal (red test lead) to anode & COM terminal
(black test lead) to cathode.
The measured value shows on the display.
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

Capacitance Measurement (see figure 8)
Note
For testing the capacitor with polarity, connect the
red test lead to anode & black test lead to cathode.
When capacitance testing has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing
leads away from the input terminals of the Meter.
The Meter's capacitance ranges are: 1.000nF, 10.00nF,
100.0nF, 1.000 F, 10.00 F, and 100.0 F. To measure
capacitance, connect the Meter as follows:
1. Insert the red test lead into the terminal and
the black test lead or test clip into the COM terminal.
2. Set the rotary switch to and press button
to select capacitance measurement mode..
3. Connect the test leads or the test clips across with
the object being measured.
The measured value shows on the display.
