GENERAL INSTRUCTIONS

1.1. Precautions and safety measures

1.1.1. Before using

You have just acquired a 4,000-count multimeter
clamp. We thank you for your confidence.
This multimeter clamp complies with the IEC 61010
norms concerning electronic measuring instruments.
For your own safety and to prevent damage to the
instrument, you must follow the instructions given in
this manual.
∗
This instrument can be used for measurements
on circuits in installation category II, in an environment
with pollution level 2, for voltages no greater than
300 V in relation to the earth.
∗
Definition of the installation categories
(see IEC 61010-1 publication):
CAT I: CAT I circuits are circuits protected by low
level transient over-voltage limiters
Example: protected electronic circuits
CAT II: CAT II circuits are household or similar
appliance power circuits, which may carry
medium-level transient over-voltage.
Example: household appliance and portable tool
power supplies
CAT III: CAT III circuits are high-power appliance
power circuits, which may carry high-level
transient over-voltage.
Example: industrial machinery or instrument
power supplies
CAT IV: CAT IV circuits are circuits which can
carry very substantial transient over-voltage.
Example: power feeders
For your own safety, only used leads that comply with
the IEC 61010 norm. Before using them, always
check that they are in perfect working order.
