4. EF Measurement
⚠ Warning
To avoid harm to the Meter, never input higher than 300V
voltage, although it is possible to measure higher voltage.
Set the switch to V
EF and remove the test lead from
the input terminal.
Press SELECT to select EF measurement mode.
Place the positive terminals towards the object being
measured.
5. Ω
auto measurement
⚠ Warning
To avoid damages to the Meter or to the devices under lest,
disconnect circuit power and discharge all the high-voltage
capacitors before the measurement.
Set the switch to Ω
Auto measurement mode is default, in this mode, you can
measure Resistance, Diode, Continuity and Capacitance
automatically.
For better accuracy, it is better to separate the object being
measured from the circuit before the measurement.
When voltage measurement has been completed,
disconnect the testing leads from the circuit under lest.
Note:
In auto measurement mode, when input:
Resistance: <15Ω or >10MΩ
Capacitance: <400pF or >1mF
You will get an irresponsible value.
6. Resistance Measurement
⚠ Warning
To avoid damages lo the Meler or to the devices under lest,
disconnect circuit power and discharge all the high-voltage
capacitors before measuring the resistance.
Set the switch to Ω
Press SELECT to select Ω measurement mode.
Connect the test leads to the object being measured.
When resistance measurement has been completed,
disconnect the testing leads from the circuit under test, and
remove the testing leads from the input terminals of the
Meter.
7. Continuity Test
⚠ Warning
To avoid damages to the Meter or to the devices under test,
disconnect circuit power and discharge all the high-voltage
capacitors before the continuity test.
To measure resistance, do the following:
Set the rotary switch to Ω
Press SELECT to select
measurement mode.
Connect the test leads to the object being measured.
The buzzer will sound continuously if the resistance of
a circuit under test is ≤30Ω; it indicates the circuit has a
good connection.
Note:
When continuity measurement has been completed,
disconnect the testing leads from the circuit under test, and
remove the testing leads from the input terminals of the
Meler.
8. Diodes Test
⚠ Warning
To avoid damages to the Meter or to the devices under test,
disconnect the circuit power and discharge all the high-
voltage capacitors before measuring diodes.
To measure diode, do the following:
Set the rotary switch to Ω
Press SELECT to select
measurement mode.
For better accuracy, it is better to separate the object being
measured from the circuit before the measurement.
When diodes measurement has been completed,
disconnect the testing leads from the circuit under test.
9. Capacitance Measurement
⚠ Warning
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, connect the Meter as follows:
Set the rotary switch to Ω
Press SELECT to select
measurement mode.
For better accuracy, it is better to separate the object being
measured from the circuit before the measurement.
When diodes measurement has been completed,
disconnect the testing leads from the circuit under test.

⚠ Warning
Do not attempt to repair or service your Meter unless you
are qualified to do so and have the relevant calibration,
performance test, and service information.
To avoid electrical shock or damage to the Meter, do not get
water inside the case.
A. General Service
Periodically wipe the case with a damp cloth and mild
detergent. Do not use abrasives or solvents.
Clean the terminals with a cotton bar with detergent, as
dirt or moisture in the terminals can affect the readings.
Turn the Meter off when it is not in use and take out the
battery when do not use it for a long time.
Do not store the Meter in a humid, hot, explosive,

inflammable place or with a strong magnetic field.
B. Replacing the Battery
⚠ Warning
300Vrms
To avoid false readings, which could lead to possible electric
shock or personal injury, replace the battery as soon as the
battery indicator appears.
To replace the battery:
1.
Turn the Meter off. Disconnect the testing leads from
the circuit under test, and remove the testing leads
from the input terminals of the Meter.
2.
Remove the screw from the battery compartment
and separate the battery compartment from the
case bottom.
3.
Remove the battery from the battery compartment.
4.
Replace the battery with a new 3V battery.
