If user of the equipment requires a
continuous operation even during
failure of main source, use of
uninterruptible power supply or
battery is recommended as power
source for the equipment.
Magnetic field

The magnetic field intensity of
source frequency must be
comparable to the level
characteristics of the magnetic field
in standard commercial or hospital
environment.
Note: As U
T
, AC main source voltage has the precedence of applied test level.
