Deîš¿nition of measurement categories
îš„Measurement category IV corresponds to measurements taken at the source of low-voltage installations.
Example: power feeders, counters and protection devices.
îš„Measurement category III corresponds to measurements on building installations.
Example: distribution panel, circuit-breakers, machines or îš¿xed industrial devices.
îš„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 protected from accidental voltages of not more than 50 V with respect to earth in measurement category IV.
The guaranteed level of protection of this equipment may be compromised if used in a manner not speciîš¿ed by the manufacturer.
îš„Make no measurements on conductors likely to be connected to the network or to earth conductors that
are not disconnected.
îš„Do not exceed the maximum rated voltage and current and the measurement category.
îš„Never exceed the protection limits indicated in the speciîš¿cations.
îš„Comply with the conditions of use, namely the temperature, the humidity, the altitude, the degree of pollution, and the place of use.
îš„ Do not use the device or its accessories if they seem damaged.
îš„Use only the charging unit supplied with the tester to recharge the internal battery.
îš„Use connection accessories of which the overvoltage category and service voltage are greater than or equal to those of the
measuring device (50V CAT IV). Use only accessories that comply with safety standards (IEC 61010-2-031 and 32).
îš„Troubleshooting and metrological checks must be done only by accredited skilled personnel.
îš„Wear the appropriate protective gear (insulating boots and gloves).
Foreword:
The potentials on the various rods used for an earth measurement may be di󰀨erent if a nearby electrical installation is defective or
certain weather conditions prevail (thunderstorms). It is up to the operator to decide whether to continue or postpone a campaign
of measurements in a given situation.
WARNING, risk of DANGER! The operator must refer to these instructions whenever this danger symbol appears.
Equipment protected by double insulation.
Earth terminal.
CE marking indicates conformity with European directives, in particular LVD and EMC.
The rubbish bin with a line through it indicates that, in the European Union, the product must undergo selective disposal
in compliance with Directive WEEE 2012/19U/EU. This equipment must not be treated as household waste.
Thank you for purchasing a C.A 6472 earth and resistivity tester. To obtain the best service from your unit:
îš„read these operating instructions carefully,
îš„comply with the precautions for use.
