3.  When the measuring voltage is greater than about 0.8V, whether ac voltage or DC voltage, the instrument will compare with the size of the DC component and AC component, take its larger component, and then according to the size of the measured value in 6V/60V/600V/750V/1000V (maximum AC voltage 750V, maximum DC voltage 1000V) between the automatic switch, Then the measured measurement value is displayed on the liquid crystal. When the measured resistance is less than about 50 , the built-in buzzer sounds.

Note

1. Indicates the maximum input voltage is 750V AC or 1000V DC.
2. If the meter measured high voltage, please be careful to shock.
3. Disconnect the test lead from the circuit under test after all measurement operations have been completed.

AC & DC Current Measurement

Warning
Risk of electric shock Do not attempt to make current measurements on the circuit when the voltage between the open circuit voltage and the ground exceeds 250V. If the fuse is blown during measurement, it may damage the meter or yourself. To avoid damage to the meter or the device under test, check the fuse of the meter before making current measurements. When measuring, use the correct input sockets, function gears, and measuring range. When the test pen is inserted in the current input socket, do not connect the other end of the test pen to any circuit in parallel.

1. Connect the black test lead to the COM input socket. connect the red test lead to the current input socket; the meter can identify the AC or DC current automatically.
2. Disconnect the circuit under test. Connect the black test lead to the disconnected (lower voltage) end of the circuit, and connect the red test lead to the other end of the disconnected circuit (which has a higher voltage).
3. Connect the circuit power, and then read the displayed readings. If the display only shows “OL”, this means that the input exceeds 10A.

Diode Test

Warning
Risk of electric shock.

To avoid damage to the meter or the device under test, all power to the circuit under test should be cut off and all high voltage capacitors fully discharged before measuring the resistance.

Test a diode outside the circuit

2. Connect the other end of the red stylus to the diode anode and the other end of the black stylus to the diode cathode for testing.
3. The meter shows the approximate forward voltage drop of the diode under test. If the polarity of the test leads is reversed, the meter will display “OL.”

In the circuit, the normal diode should produce a forward voltage drop of 0.5V to 0.8V; however, the reverse bias reading will depend on the change in resistance of the other channels between the two test leads

Capacitance Measurement

Risk of electric shock.
To avoid damage to the meter or the device under test, disconnect all power to the circuit under test and fully discharge all high-voltage capacitors before measuring capacitance. DC voltage gear to determine the capacitor has been discharged.

1. Insert the red and black test lead into the input jack, Press “SEL” button to the capacitance test.
2. After the capacitor is completely discharged, the other end of the red and black pen is connected to both ends of the capacitor to be measured. And the LCD reads the measured capacitance value.

Note

1. To improve the accuracy of measurements below 10nF, subtract the distribution capacitance of the meter and leads.
2. When measuring large capacitance, stable reading takes a certain amount of time.
3. When measuring polar capacitors, pay attention to the corresponding polarity to avoid damaging the instrument.
