– guidelines
The quality of
the supply volt-
age should cor-
respond with a
typical store or
hospital envi-
ronment. If the
user of the DSO
364 model also
requires that
the function
continues after
interruptions
to the power
supply, it is
recommended
that you supply
the DSO 364
model from an
uninterrupted
power supply
or battery.
Magnetic fields
associated with
the mains fre-
quency should
correspond
to the typical
levels encoun-
tered in a store
or hospital
environment.
