Compatibility with Electromagnetic Immunity (1)
The VS-1500 is intended for use in the electromagnetic environments described below. It is
recommended to verify that the VS-1500 is used in such an environment.
Immunity Test
IEC 60601-1-2 Test
Level
Compatible Level Electromagnetic Environment/Guidance
Electrostatic
discharge (ESD):
IEC 61000-4-2
±2, 4, 6 kV, contact

Floors should be made of wood,
concrete or ceramic tiles. In a room
with a floor covered with synthetic
material, the relative humidity
should be at least 30%.
Electrically fast

The power supply should be of the
same quality as a commercial or
hospital line.

If continuous operation is required at
all times regardless of power
outages, connect the VS-1500 to an
uninterruptible power supply (UPS)
device.

of the power supply should be the
same level as a standard
commercial or hospital line.
