SAFETY WARNINGS

• Safety Warnings and Precautions must be read and

understood before the instrument is used. They

must be

observed during use.

• The circuit under test must be de-energised and isolated

before connections are made except for voltage measurement.

• Circuit connections must not be touched during a test.

• After insulation tests, capacitive circuits must be allowed to

discharge

before disconnecting the test leads.

• The Live Circuit Warning and Automatic Discharge are additional

safety features and

should not be regarded as a substitute for

normal safe working practice.

• Replacement fuses must be of the correct type and rating.

Failure to fit the correctly rated fuse

will result in damage to the

instrument in the event of an overload.

• Test leads, including crocodile clips, must be in good order,

clean and have no broken or cracked insulation.

• Ensure that hands remain behind guards of probes/clips when

testing.

• U.K. Safety Authorities recommend the use of fused test leads

when measuring voltage on high energy systems.

NOTE

THE INSTRUMENTS MUST ONLY BE USED BY

SUITABLY TRAINED AND COMPETENT PERSONS

Users of this equipment and/or their employers are reminded that

Health and Safety Legislation require them to carry out valid risk

assessments 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 assessments 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.

Symbols used on the instruments are:

Caution, risk of electric shock.

Caution, refer to User Guide.

Equipment protected throughout by

Double Insulation (Class II).

Equipment complies with current EU Directives.

Equipment must not be connected

to installations >500V.
