Precautions and safety measures

1.1.1. Preliminary

- This device can be used for measurements on category ΙΙΙ installations, for voltages
never exceeding 600 V (AC or DC) relative to the earth.
- Definition of overvoltage categories (see. publication IEC 664-1) :
CAT I : The CAT I circuits are protected by safety measures limiting transient
overvoltages to appropriate low level.
Example : protected electronic circuits
CAT II : The CAT II circuits are power supply circuits of appliances or portable
equipment with transient overvoltages of an average level.
Example : appliances and portable equipment
CAT III : The CAT III circuits are power supply circuits of power equipment with
high transient overvoltages.
Example : fixed installation or industrial equipment
CAT IV : The CAT IV circuits may comprise very high transient overvoltages.
Example : primary supply level
When using this multimeter, the user must observe all normal safety rules concerning:
- protection against the dangers of electric current.
- protection of the multimeter against misuse.
For your own safety, only use the test probes supplied with the instrument and,
check, before use, that they are in good working condition.

1.1.2. During use

Test equipment risk assessment
are reminded that Health and Safety Legislation requires them to carry out a valid
risk assessment of all electrical work so as to identify potential sources of electrical
danger and risk of electrical injury such as from inadvertent short circuits. Where the
assessment show that the risk is significant then the use of fused test leads
constructed in accordance with the HSE guidance note GS38 "Electrical Test
Equipment for use by Electricians" should be used.
Never exceed the protection limit values indicated in the specifications for each type of
measurement.
