Precautions and safety measures
1.1.1. Before using the tester
∗
This instrument is designed for use indoors, within a pollution level 2 environment, at an
altitude of less than 2000 m, at a temperature of between 0°C and 45°C, with 80 %
relative humidity up to 31°C.
∗
It can be used for testing category III installations, with voltages that do not exceed
300 V in relation to the earth.
∗
Definition of installation categories :
•
CAT IV:
Measurement category IV corresponds to measurements taken at the source of
low-voltage installations.
Example: power feeders
•
CAT III:
Measurement category III corresponds to measurements on building
installations.
Example: industrial machinery or instrument power supplies
•
CAT II:
Measurement category II corresponds to measurements taken on circuits
directly connected to low-voltage installations.
Example: household appliance and portable tool power supplies
•
CAT I:
Measurement category I corresponds to measurements taken on circuits not
directly connected to the network.
Example: protected electronic circuits
∗
The leads and connection accessories used must be designed for a specific voltage and
an over-voltage category equivalent at least to that of the circuits on which the
measurements are carried out.
∗
The safety of any system incorporating this instrument is the responsibility of the system
assembler.
Check the condition of the instrument, leads and connection accessories before
