Chapter 1

Meter Safety Standards

This style of digital multimeter is designed and manufactured according to the safety requirements

set out by the IEC1010-1 standards for electronic test instruments and the hand-hold digital

multimeters. Its design and manufacture is strictly based on the provisions in the 1000V CAT III of

IEC1010-1 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 voltage 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 injure 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.

 Keep batteries out of reach of children.

 If a battery leaks, remove all batteries, taking care to keep the leaked fluid fromtouching your

skin or clothes. If fluid from the battery comes into contact with skin or clothes, flush skin with

water immediately. Before inserting new batteries, thoroughly clean the battery compartment with

a damp paper towel, or follow the battery manufacturer’s recommendations for cleanup.

 Dispose of batteries in accordance with local and national disposal regulations, including those
