1.Safety Precautions

●Use the meter near the equipment with large electromagnetic interference,

the reading of the meter will be unstable, and even may produce larger errors.

●Do not use when the appearance of the meter or test leads is damaged.

●If the instrument is not used correctly, the safety function provided by the

instrument may be invalid.

● Extreme care must be taken when working around exposed conductors or

busses.

●It is forbidden to use this instrument near explosive gas, steam or dust.

●The correct input terminal, function and range must be used for measure-

ment. The input value must not exceed the input limit value speciﬁed in each

range to prevent damage to the instrument.

●When the meter is connected to the line under test, do not touch the unused

input terminals.

●When the measured voltage exceeds the rms value of 60V DC or 30V AC, be

careful to prevent electric shock.

●When measuring with a test lead, place your ﬁnger behind the protective ring

of the test lead.

●Before changing the range, make sure that the test lead has left the circuit

under test.

●For all DC functions, in order to avoid the risk of electric shock due to possible

incorrect readings, please use the AC function ﬁrst to conﬁrm whether there is

any AC voltage. Then, select a DC voltage range that is equal to or greater than

the AC voltage.

●Before performing resistance measurement or continuity test, the power

supply of the circuit under test must be cut oﬀ, and all high-voltage capacitors in

the circuit under test must be discharged.

●Do not measure resistance or conduct continuity tests on live circuits.

●Do not put it in an explosive and ﬂammable place when not in use.

●When repairing TV sets or measuring power conversion circuits, be careful of

high-amplitude voltage pulses in the circuit under test to avoid damage to the

meter.

2

3. Input protection measures

●When performing voltage measurements, the maximum input voltage that

can withstand is 1000V, either DC or AC.

●Can withstand no more than 250V AC voltage or equivalent eﬀective

value voltage.

●When opening the case of the instrument or removing the battery cover, the

test lead should be pulled out ﬁrst.

●When repairing the instrument, be sure to use the designated replacement

parts.

●Before turning on the instrument, you must disconnect all related power

sources, and you must also ensure that you do not have static electricity to

prevent damage to the components of the instrument.

●For accurate and correct calibration or maintenance of the instrument, you

should return it to the factory.

●When opening the case of the meter, it must be noted that some capacitors in

the meter still hold dangerous voltages even after the meter is powered oﬀ.

●If any abnormality is observed in the instrument, the instrument should be

stopped immediately and sent for repair. And make sure that it cannot be used

until it passes the inspection.

●When not in use for a long time, and avoid storing in places with high tempera-

ture and high humidity.

●This product uses 3.7V/1000mA lithium battery for power supply, and the

battery must be correctly installed in the battery box of the instrument.

●When the battery undervoltage symbol appears, please charge it in time. A

low battery can cause the meter to read incorrectly, which could result in electric

shock or personal injury.

●In the measurement category, the voltage measurement should not exceed

1000V.

●Do not use the instrument when the protective case (or part of it) is removed.

Automatic measurement

Note

●Do not measure any voltage higher than 1000V DC/1000V AC to prevent

electric shock or damage to the instrument.

●Do not apply more than 1000V DC voltage/1000V AC voltage between the

common terminal and the ground to avoid electric shock or damage to the

instrument.

In automatic mode, AC and DC voltage, resistance and continuity can be automati-

cally measured.

1. After power on, it will automatically switch to "AUTO" automatic measurement

mode.

2. Connect the black test lead and the red test lead to the COM input jack and the

INPUT input jack respectively.

3. Use the test pen to measure the voltage value, resistance value and short-circuit

point of the circuit to be tested at both ends. (parallel to the circuit under test)

4. At this time, the liquid crystal display will display the corresponding measured

voltage value and resistance value at the same time. When measuring DC voltage,

the display will show the voltage polarity connected to the red test lead at the

same time. If the measured resistance value is less than 50Ω, the buzzer will issue

an alarm sound.

1. When measuring low resistance, in order to measure accurately, please ﬁrst

short-circuit the two test leads to read the short-circuit resistance value of the

test leads, and subtract the resistance value after measuring the measured

resistance.

Notice

When the measured DC voltage is less than 0.75V and the AC voltage is less

than 0.75V, the displayed resistance value may appear, because the

minimum measurement voltage value of this product is 0.75V, and the

minimum AC voltage is 0.75V.

Press the key ,place the top of the meter close to the conductor, if the meter

detects AC voltage, the meter will The signal strength of , when the sensed

voltage is low , the screen signal will display low: , medium: ,

high: , and at the same time the buzzer emits alarm sounds of

diﬀerent frequencies.

NCV test

2. In the 10M range, it will take a few seconds for the reading to stabilize. This is

normal for high resistance measurements.

3. When the meter is open circuit or the resistance value of the measured object

is too large, the display will display "OL", indicating that the measured value

exceeds the range

Notice

●Even without indication, voltage may still be present. Do not rely on

non-contact voltage detectors to determine lead

Whether there is voltage on the line. Probing operations may vary by socket

design, insulation thickness and type, etc.

inﬂuence of factors.

●When the input terminal of the meter enters the voltage, the buzzer will

also sound due to the existence of the induced voltage.

ment mode, and then press the SEL key to switch to the " " diode

measurement mode.

2. Connect the black test lead and the red test lead to the COM input jack and the

INPUT input jack respectively.

3. Connect the black test lead and the red test lead to both ends of the object to

be tested.

4. If the measured object is a diode, the red and black test leads should be

placed on the positive and negative ends of the diode respectively, and the

meter will display the positive bias value of the tested diode. If the polarity of the

test leads is reversed or the test points are connected if the polarity of the tubes

is reversed, the meter will display "OL". In the circuit, a normal diode should

produce a forward voltage drop of 0.5V to 0.8V; but the reading of the reverse

bias voltage will depend on the change in the resistance value of the other

channels between the two test leads.
