Safety requirement
CN
To avoid the risk of short circuits or electric shock inside the instrument, do
not operate the instrument in a damp environment.
Altitude
Operating and Non-operating: 2,000m.
This product is powered by mains conforming to installation (overvoltage)
category II.
Warning:
Ensure that no overvoltage (e.g. from lightning) reaches the product. Otherwise,
the operator may be in danger of receiving electric shock.
Installation (Overvoltage) Category Definitions.
Installation (overvoltage) category I
refers to the signal level, which is suitable
for measuring terminals connected to equipment in the source circuit, where
measures have been taken to limit instantaneous voltage to the corresponding
low level.
Installation (overvoltage) category II
refers to the local distribution level, which
is suitable for equipment connected to the mains (AC power supply).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
⚫
Pollution Degree 1:
No pollution or only dry, nonconductive pollution
occurs. The pollution has no effect. For example, a clean room or air-
conditioned office environment.
⚫
Pollution Degree 2: Normally only nonconductive pollution occurs.
Temporary conductivity caused by condensation is to be expected. For
example, indoor environment.
⚫
Pollution Degree 3:
Conductive pollution or dry nonconductive pollution
that becomes conductive due to condensation occurs. To be found in
industrial environment or construction sites (harsh environments). For
example, sheltered outdoor environment.
⚫
Pollution Degree 4: The pollution generates persistent conductivity caused
by conductive dust, rain, or snow. For example, outdoor areas.
