1.2 Definition of Measurement Categories
CAT IV:
Corresponds to measurements performed at
primary electrical supply (< 1000 V).
Example: primary overcurrent protection
devices, ripple control units, and meters.
CAT III:
Corresponds to measurements performed in the
building installation at the distribution level.
Example: hardwired equipment in fixed
installation and circuit breakers.
CAT II:
Corresponds to measurements performed
on circuits directly connected to the electrical
distribution system.
Example: measurements on household
appliances and portable tools.
1.3 Precautions for Use
■ Read the user manual before operating and follow all
safety information. Only use the meter as specified in
this user manual.
■ 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.
■ Never use this meter on a circuit with voltages greater
than 600 V
■ Never measure current while the test leads are
connected to the input jacks.
■ Do not operate the meter if the body or test leads look
damaged.
■ Do not perform resistance and continuity test on a live
circuit.
■ Use extreme caution when measuring live systems with
voltages greater than 60 V
■ Use extreme care when working around bus bars and
bare conductors.
■ Do not use the meter in overrange/overload conditions (OL).
■ For accurate readings, change the battery when the
symbol appears.
