INSTUCTION MANUAL

一、GENERAL

This instrument adopts the DC Voltage convertor of low
consumption and high converter ratio inductance energy
storage, to change the 9V Voltage to 250V/500V/1000V DC
Voltage. It uses digital bridge to make the insulation
resistance measurement had the features of user-friendly,
high extent range, backlight display, data hold and auto
power off. The whole instrument is stylish and superior grade
in appearance and high stable in performance, it can be
operated by both hands through using a shoulder strap. It is
most suitable for the needs of insulation resistance check,
such as electric, cable, electrical and mechanical equipment,
telecommunication equipment and electrical facilities.

四、OPERATION DESCRIPTION：

1、Open the battery case and set up 6pcs of 5# batteries

(see the following pictures), note the polarity of
batteries.

2、Press the button of“POWER”.
3、Select the right voltage (250V/500V/1000V/AC750V) according

to the requirement of measurement.

4、Select the right range (RANGE) (except AC750V), according to

the requirement of measurement.

5、Connect the electrode of the measured object to the relative

terminal of the instrument.

6、When measuring cable, connect G Terminal to the protection

loop.

7、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.

8、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.

9、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 “ “position, it
expresses that the insulated resistance exceeds

2000MΩ.

10、Hang the instrument on your neck to save your hands

to make measurement.

五、METHOD TO MEASURE THE INSULATED RESISTANCE：

六、SAFETY NOTES:

1、When voltage measurement selection button does not be

pressed, it is possible to appear the high voltage at the
output voltage terminal.

2、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

3、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.

4、When measuring, it is not allowed to handle the terminal

of measurement to make sure the accuracy of reading
and personal safety.

5、Keep the instrument away from the high temperature

place, and from the direct sunshine to avoid affecting
the life of the LCD.

6、When low battery symbol of “ ” appears, please

replace the batteries in time. Take the batteries out
when storage to avoid the leakage of batteries to
damage the instrument.

7、When unload, reading is normal, it won’t affect the

measurement.

8、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

9、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.

10、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.
