The quality of main
power supply must be
equal to the quality of
power supply that is used
in general commercial or
medical environments. If
operation must continue
during a failure of the
main power, it is
recommended that power
is supplied through an
uninterruptible power
supply or a battery .

The electromagnetic field
from power frequency
must be equal to the EM
field in general
commercial or medical
environments.
Note: Uт is the primary voltage (AC) before applying test level.
