(4) If the rotation is counter-clockwise, LCD
will display "L " .

(5) Testing tips:
This measurement use tester as a virtual
ground; if equipment or user is not with
proper insulation condition, measure-
ment may not function properly.
5.3 Non-contact Voltage Sensing
(1) To switch on the function, press the
„LIGHT / NOT-CONTACT SENSING
SWITCH" , LCD will display „DE-" .
(2) Non-contact voltage indicator „
the top right of the main probe will light
up and buzzer will buzzing when the
sensor is near electromagnetic file
greater than 90VAC.
(3) Press the "LIGHT / NON-CONTACT SEN-
SING SWITCH" again to switch off the
function.
(4) This function will automatically switch
off after 3 minutes.

5.4 Continuity
CAUTION
(1) Please make sure there is no live
voltage in the circuit before continuity
L
measurement.
(2) Connecting the two probe to the to cir-
cuit wish to test, press both "ON / OFF
SWITCH" on two probes, if the circuit is
continued, all indicator on the LCD will
flashing, and buzzer will be buzzing.
CAUTION
(3) If the circuit is continued, equipment
shall act like self-diagnostic.
5.5 Illumination
(1) Long press and hold the "LIGHT / NON-
CONTACT VOLTAGE SENSING SWITCH"
to switch on the illumination light.
" on
CAUTION
(2) Illumination function and non-contact
voltage sensing function share the same
button, please operating these two
functions carefully.

6. Battery Replacement
Please do not operate any functions and
move the equipment away from the vol-
tage source when replacing the batteries.
If LCD flash 5 times then switch off auto-
matically during selfdiagnostic or voltage
measurement, it indicating the equipment
is run out of the battery power. Please
change the batteries.
Battery power level will also display
on the LCD during the voltage measu-
rement; please take caution with the
battery power level.
(1) Unlock the battery cap by a coin.
(2) Open the battery cap and replace the
battery. Please take care of the battery
polarity.
(3) Put back the battery cap and lock it by
a coin.
Please make sure the battery cap is
locked before any operation.
