3. Operation description
Open the battery case and set up 6pcs of batteries (see the following pictures), note the polarity of batteries.
Press the button of“POWER”.
Select the right voltage (250V/500V/1000V/AC750V) according to the requirement of measurement.
Select the right range (RANGE) (except AC750V), according to the requirement of measurement.
Connect the electrode of the measured object to the relative terminal of the instrument.
When measuring cable, connect G Terminal to the protection loop.
Press the button of measurement and start it, turn the knob right to lock the button; when the value is stable, get
the reading from LCD.
Connect the input line “E” to the ground of the measured object, and “L” to the circuit of the measured object;
require line “L” to hang in the air.
2000MΩ�When “1” is displayed, over range is indicated, and should turn to the higher range to get reading;
When the range button is in “PRESSED“ position, it expresses that the insulated resistance exceeds 2000MΩ.
Hang the instrument on your neck to save your hands to make measurement.

5. Safety Notices
• When voltage measurement selection button does not be pressed, it is possible to appear the high voltage at
the output voltage terminal.
• When measuring, first check the measurement voltage selection and if the indication of the measurement
voltage on LCD is in accordance with the voltage needed
• To ensure the safety of operation, the operation cannot be done until the measured object removed from the
power supplied by the electricity grid system, and should be discharged fully to testify that the measured
object does not have any danger of power.
• When measuring, it is not allowed to handle the terminal of measurement to make sure the accuracy of reading
and personal safety.
• Keep the instrument away from the high temperature place, and from the direct sunshine to avoid affecting
the life of the LCD.
• When low battery symbol of “BATTERY” appears, please replace the batteries in time. Take the batteries
out when storage to avoid the leakage of batteries to damage the instrument.
• When unload, reading is normal, it won’t affect the measurement.
• When measuring MΩ, if the reading is unstable, it is likely caused by the interference of surrounding and
unsteadiness of the insulated materials, it will make the reading stable to connect the “G” terminal to the
shield side of the measured object

• To ensure the safety of measurement and reduce the interference, the test leads adopt silicone rubber materials,
please do not change the leads at will.
• When the external AC adaptor supplies the power, the inside batteries are disconnected and the batteries can’t
be charged at the time. Note: please select () power supply method.
