Ⅱ. Operating Instructions

When using the instrument for the first time or facing the energy

shortage of the batteries, please open the cover of the battery box and

put 6 5# batteries into it. Pay attention to the battery polarity.

When external adapter is supplying power, the internal battery power will

be cut off, and the battery cannot be charged at this time.

Attention: Please choose the power supply mode ( ).

Insulation Resistance Measurement

1. Turn the knob to the position of the corresponding function in

accordance with the measuring requirement.

2. Connect the electrode of tested object to the corresponding jack of the

instrument.

3. Connect Jack G to the protection ring when testing the cable.

4. Press the test switch and the test will be carried out. When the display

value is stable, the reading will be ready. Press the right knob to lock the

continuous test, and turn the left knob to release the continuous test;

when the test switch is pressed, the high voltage red warning light will

light up, the high voltage symbol will appear on the screen, and the

buzzer will sound "Di Di": when the measured insulation resistance is

less than 5% of the range or short circuit, the buzzer will give a long

sound warning.

5. Connect the red test pen "E" to the end of the measured circuit and the

black test pen "L" to the GND end of the measured object; the lead "E"

should be suspended in midair as far as possible.

6. If only "1" is displayed in the top digit, it means the measuring range is

exceeded, and a higher range gear needs to be selected.

Attention:

(1)When the test switch is pressed, the output end "E" will output high

voltage, please be careful.

(2) When testing, check whether the selection of test voltage and the

prompt of test voltage on LCD are consistent with the required voltage.

(3) In MΩ test, the unstable reading may be caused by environmental

interference or unstable insulation material. In this case, the "G" end can

be connected to the shielded end of the tested object to stabilize the

reading.

Diagram of the method to measure insulation resistance

Resistance and Continuity Measurement

1.Turn the knob to the gear of 2000V.

2.Connect the red test pen to the "V/Ω" input end, and connect the black

test pen to the "G" input end.

3.Cross-connected the test rod to the circuit to be measured, and the

data will display on the screen.

4.When the measured resistance is less than 50Ω, the buzzer will make a

sound.

Attention:

(1)If the resistance value exceeds 2KΩ or the open-circuit state occurs,

“1” will be displayed on the screen.

(2)When measuring online resistance, make sure that all the power

supply of the measured circuit has been turned off and all the

capacitance has been fully discharged before carrying out measurement.

(3)Large errors that occur during measurement may be caused by the

influence of other components online or the electric potential at both

ends of the resistance.

(4)Please do not input voltage in resistance measuring range.

DC Voltage Measurement

1.Turn the knob to the gear of 1000V.

2.Connect the red test pen to the "V/Ω" input end, and connect the black

test pen to the "G" input end.

3.Cross-connect the test rod to the circuit to be measured. The voltage

and polarity of the point to which the red test rod connects will be

displayed on the screen.

Attention:

(1)If there is residual number on the screen when measurement has not

started yet, it is a normal phenomenon which will not influence the

measurement. If "1" is displayed on the top digit, it means the measuring

range is exceeded.

(2)Input voltage must not exceed DC 1000V. If so, the circuit of the

instrument may be damaged.

(3)When measuring high voltage circuit, be careful not to touch the high-

voltage circuit.

AC Voltage Measurement

1.Turn the knob to the gear of 750V

2.Connect the red test pen to the“V/Ω”input end, and connect the black

test pen to the “G”input end.

3.Cross-connect the test rod to the circuit to be measured. The voltage

and polarity of the point to which the red test rod connects will be

displayed on the screen.

Attention:

(4)If there is residual number on the screen when measurement has not

started yet, it is a normal phenomenon which will not influence the

measurement. If “1”is displayed on the top digit, it means the measuring

range is exceeded.

(5)Input voltage must not exceed AC 750V. If so, the circuit of the

instrument may be damaged.

(6)When measuring high voltage circuit, be careful not to touch the high-

voltage circuit.
