: 2
1) Connected to an oscilloscope with an input impedance
of 1 MΩ ± 1 %.
2) Measurement category I
Defi nition: Measurement category I is for measure-
ments performed on circuits not directly connected
to a mains supply.
Examples: Measurements in circuits not derived
from a mains supply and specially protected (internal)
circuits derived from a mains supply. In the latter
case, transient stresses are variable; for that reason
requires that the transient withstand capability of the
equipment is made known to the user.
Measurement category II (CAT II)
Defi nition: Measurement category II is for measure-
ments performed on circuits directly connected to
the low voltage installation.
Examples: Household appliances, portable tools and
similar equipment.
3) Pollution degree 2
Only non conductive POLLUTION. Occasionally, how-
ever, a temporary conductivity caused by conden-
sation must be accepted.
