Note:Median resistance: to ensure that the voltage of both sides of measurement is not less than 90% of lower
limit of resistance measurement of measurement voltage normal value.
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.
