Denition of measurement categories

Measurement category IV corresponds to measurements taken at the source of low-voltage installations.

Example: power feeders, counters and protection devices.

Measurement category III corresponds to measurements on building installations.

Example: distribution panel, circuit-breakers, machines or xed industrial devices.

Measurement category II corresponds to measurements taken on circuits directly connected to low-voltage installations.

Example: power supply to electro-domestic devices and portable tools.

PRECAUTIONS FOR USE

This instrument is compliant with safety standard IEC IEC/EN 61010-2-30 or BS EN 61010-2-30 for voltages up to 600V in category IV.

Do not use the instrument for measurements on circuits that are not in measurement categories II, III, or IV or that might be con-

nected inadvertently to circuits that are not in measurement categories II, III, or IV.

The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken

in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.

 If you use this instrument other than as specied, the protection it provides may be compromised, thereby endangering you.

Do not use the instrument on networks of which the voltage or category exceeds those mentioned.

 Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.

 Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation

is deteriorated (even partially) must be set aside for repair or scrapping.

 Before using your instrument, check that it is perfectly dry. If it is wet, it must be thoroughly dried before it can be connected or

used.

 Use only the leads and accessories supplied. The use of leads (or accessories) of a lower voltage or category limits the voltage

or category of the combined instrument and leads (or accessories) to that of the leads (or accessories).

 Use personal protection equipment systematically.

Thank you for purchasing a C.A 6422 or C.A 6424 earth tester.

To obtain the best service from your instrument:

read this user manual carefully,

comply with the precautions for use.
