Ths
series
of m~ltimeters
is
the atest high-seneitvlty pointer-type mutmeters made of rare earth
magnetc materlas covered with soft rubber seeves, shockproof and drop-resistant. Designed to

The nstniment
uses
Wo
1.5V AAA banenes for power supply, and the baheries must be cnrrectly
instailed In the banery box of the instrument.
'
When the adjustment of the resstance scale 1s less than
Zero
it means that the banery
in
the meter 1s
exhausled Please repiace the battery mmediately to
ensure
Ihe measurement accuracy and prevent the
banery
electrolyie from averflowing and corroding the pans
in
the meter
'
Never
use
the meter wth the

'
When ucing the 2500V gear to measure hgh voltage you must wear rubber gloves
on
your hands and
measure

'
Before turning
on
the meter. you must cut
off
all relevant power cuppl~ec, and you must also
ensure
that
you da not have statc eectricity to avod damage to the components of the meter

When opening the rneter case it must be nated that some capaciton Inside the meter hold dangerous
voltages even ailer the meter

the meter, the meter should be taken out of selvice immediately and
sent for repair And make sure that it cannot be used before passing the inspection

When measuring PA current and mA current. it
is
pratected by

self-recnvery fuse 1s activated. the heat is severe and you must wait for 30 seconds before measunng
again, atherwlse Ihe measurement accuracy may be affected

the meter will be unstabie. and may
even
aause large errors.
'Do not

'lf the meter is not used conectly. the safety functon provided by Ihe meter may be mpaired.
'When warking around evpased conductom ar buses. t is forbdden ta tauch the canductor wires, and
measure wark under the premise af ensunhg safety.
Do not use ths instniment near explosive gas. vapar ar dust.
'
The correct input terminal. function and range must be used for measurement.
'
The ~nput value must not exceed the input Iimit value specified
in
each range to prevent damage to the
tnstrument
Do not tauch unused inputs when the mder
