Meter Safety Standards
This style of digital multimeter is designed and manufactured according to the safety requirements
set out by the IEC61010-1 standards for electronic test instruments and the hand-hold digital
multimeters. Its design and manufacture is strictly based on the provisions in the 1000V CATIII of
IEC6060-1 and the Stipulation of 2-Pollution Grade.
The meter conforms to the European Union’s following requirements:89/336/EEC
(EMC Electromagnetic Compatibility ),73/23/EEC(LVD Low Voltage Protection)and 93/68/EEC
(CE Mark).
Warning
•
Before use of the meter firstly check up if there is any crack on the outer shell or if it lacks any
plastic part, and check up whether the testing line is damaged or has any exposed metal.
The meter can be used only if no any insulating problem be found.
•
Carefully read the operating methods and safety prompts in this manual. Using it not based on the
methods specified in this manual may cause the meter damaged.
•
Non-normal meter must not be used. It should be sent for repairing.
•
The meter must not be used in an environment with combustible gases, steam or dust pollution.
•
It should be careful to work when measuring votage higher than 30Vac(effective value)or 50Vdc
for such voltage having the risk of shock. Avoid the body directly touching ground or any metal
substance in which there may be ground
•
potential during measuring. The body should be kept insulated from ground with dry insulating
shoes, insulating pads or insulating clothes.
•
When performing measurement with a test probe your fingers should be put behind a finger-
protector.
•
Must not try to measure a voltage higher than 1000VAC or 1000VDC,the meter may be damaged
and the operator’s safety may be threatened if the limit for voltage measurement be exceeded.
•
When the symbol for electric insufficiency appearing on the display screen it is necessary to
replace the batteries for avoiding the possible shock or injury resulted in by erroneous reading.
•
In case of replacing batteries, it is necessary firstly to pull out the testing line. AA batteries should
be used and they should be put into the meter with the proper polarity.
•
Must not make any voltage measurement when the testing line being inserting into the current
hole.
•
Repair and calibration of the meter must be carried out by experienced professionals,
unprofessionals should not repair and calibrate the meter by themselves.
Limited Guarantee and the Liability Scope
•
This company will undertake repairs freely for any quality problem of the meter which if should be
found within 18 months from the date at which it was bought, but which not including replacement
of fuse and batteries as well as any damage caused by negligence, wrong use, pollution, change of
circuit and non-normal use.
•
For maintenance beyond the 18-month guarantee period, the company will charge a certain repair
fee and materials cost.
