TEST: In the insulation resistance testing function, pressing and

holding the "TEST" button, the meter will inject high-voltage, and

enter into the insulation resistance testing, release the "TEST" button and it

will cut off the high-voltage and exit form the insulation resistance testing.

ZERO/LIGHT: Press the "ZERO/LIGHT" button, the current values in the

primary display will be set to zero, (mainly used for 400Ω, the low

resistance testing), it will return if the button is pressed for 2 seconds, it

will enter directly into the "LIGHT" status, and the LCD backlight light up.

After 15 seconds, the backlight is shut off automatically, the same as

pressing for 2 seconds within 15s.

b) Display Indicators

The Primary Display ： Indicates the current function testing values

The Secondary Display ： It shows the output DCV while you test the

insulation resistance, and the battery voltage while the ACV

The Analog Bar ： Indicates the current function testing value in

synchronous with the primary display.

:While testing the insulation resistance, the symbol " " flashes

frequently if the voltage is over 30V.

: While testing the insulation resistance, the symbol "

frequently and the buzzer warns continually if the outside voltage is

over 30V. the symbol "

buzzer warns continuously.

LOCK: Push down the "LOCK" button while you test the insulation

resistance and the symbol "

LOBAT ： The display shows "LOBAT" when the voltage drops below 7.5V

MAX/MIN: Stand for the maximum or the minimum.

ZERO: Digital zero adjusting.

HOLD:The digital holding function for the primary display.

AC， DC: The indicator for the voltage property.

V， MΩ， Ω: The measured dimension units.

5. INSULATION RESISTANCE MEASUREMENTS

a) Turn the function switch from the "OFF" position to the left (4000MΩ/

1000V, 4000MΩ/500V, 4000MΩ/250V, 1000MΩ/125V) and choose one

of the voltage-block (there are 4 ranges namely, 4MΩ, 40MΩ, 400MΩ

and 4000MΩ can be switched automatically for every voltage-block.)

b) Connect two testing lines to the tested ；

c) Push down and hold the "TEST" button /or press the "LOCK" keystoke

first and then the "TEST" button, if the object under test is live and its

voltage (AC/DC) is over 30V, it will refuse to work and no high-voltage

testing occurs, simultaneously, it shows ">30V" on the LCD, the symbol

" " flashes, and the buzzer warns frequently. If the object under test

" is indicated while LOΩ≤35Ω and the

" is indicated.
