1. Introduction

The di gi tal multimeter is des igned and manufactu red
acco rd ing to safety require ments of EN61010-1 on
elec tr onic measuring in st rument and hand-hel d digital
mult ip urpose meter. The product me et s with the

requ ir ements of EN61010-1 6 00V CAT III and pol lu tion
degr ee 2 .
The me te r can be used for measuri ng DC voltage, AC
volt ag e, resistance, diod e, buzzer, Continuit y test,
capa ci tance, frequency, DC curre nt , AC current and
duty c yc le etc. Th e unique non-cont ac t AC voltage
dete ct ion function can prom ptly remind you to pay
atte nt ion to safety operati on, the full scale AC220 V
prot ec tion design makes you m ore safe and relieved .
This s er ies of meters can be
wide ly u sed for schools, labs , research institut es,
ente rp rises and factories e tc. various electro nic
indu st ries.
Plea se r ead this operating in struction careful ly and
pay at te ntion to related safe w orking standards be fo re
usin g th is meter, Protection p rovided by the instru ment
will b e im paired if used in a man ne r not specified by
the ma nu facturer.

2. Safety Information

The sp ec ial attention shoul d be paid when using the
mete r be cause the improper us age may cause electri c
shoc k an d damage the meter. The safety m ea sures in
comm on s afety regulations a nd operating instru ction
shou ld b e complied with whe n us ing. In order to make
full y us e of its functions and en sure safe operation s,
plea se c omply with the usage in t his section careful ly.

Warning

In order to avoid personal injury and meter damage
caused by electric shock, the following safety tips should
be paid attention to:

• Don' t me asure any voltage out o f stipulated measur ing
rang e of t he meter.

Don' t ap ply high voltage (abo ve 100V) at input end

when m ea suring resistance a nd diode.

Don' t us e the meter if the test lin e is damaged or

expo se d metal part.

Avoid using un de r direct sunlight o r hi gh temperature.
Pay at te ntion to the possibil ity of electric shock w he n

meas ur ing voltage in excess o f 36V AC or 48C DC.

Befo re m easuring current, f irstly turn off the power of
meas ur ed equipment and meas ured circuit, Elect rify
to mea su re after connecting t est leads.

Pay at te ntion to battery pola rity when changing ba ttery.
