GENERAL INSTRUCTIONS

1.1. Precautions and safety measures

1.1.1. Before use

You have just bought a clamp-on leakage meter. Thank
you for your confidence.
This clamp-on meter complies with the IEC 61010 safety
standard for electronic measuring instruments. For your
own safety, and that of the instrument, it is best to follow
the instructions given in this manual.
∗
This instrument can be used for measurements on
circuits in installation category III, in a pollution level
2 environment, with voltages not exceeding 300V
with respect to ground.

1.1.2. Measurement categories

(EN 61010-2-032, EN 61010-2-033):
MEASUREMENT CATEGORY II
MEASUREMENT CATEGORY II is applicable to test and
measuring circuits connected directly to utilization points
(socket outlets and similar points) of the low-voltage
MAINS installation. This part of the installation is
expected to have a minimum of two levels of overcurrent
protective devices between the transformer and the
connecting points of the measuring circuit.
Example: measurements on MAINS CIRCUITS of
household appliances, portable
equipment.
MEASUREMENT CATEGORY III
MEASUREMENT CATEGORY III is applicable to test and
measuring circuits connected to the distribution part of
the building's low-voltage MAINS installation. This part of
the installation is expected to have a minimum of one
level of over-current protective devices between the
transformer and possible connecting points.
Example: measurements on distribution boards (including
secondary electricity meters), circuit breakers, wiring,
including cables, bus-bars, junction boxes, switches,
socket -outlets in the fixed installation, and equipment for
industrial use and some other equipment such as
stationary motors with permanent connection to the fixed
installation.
