GUIDELINES AND MANUFACTURER'S DECLARATION - ELECTROMAGNETIC INTERFERENCE
IMMUNITY
The measurement systems in the JMT range of products are intended for operation in the
electromagnetic environment stated below. The customer or user of the JMT measurement system
should ensure that it is used in such an environment.
Immunity tests
IEC 60601- test

Floors should be made from wood or
concrete or fitted with ceramic tiles. If
the floor is equipped with synthetic
material, the relative air humidity
should be at least 30%.

The supply voltage quality should be
that of a typical commercial or hospital
environment. If the user of the
measurement systems in the JMT
range of products requires continued
functioning during power supply
interruptions, it is recommended that
the JMT jaw motion analysis system be
powered by an interruption-free power
supply or a battery.
Magnetic field

supply frequency
(50/60 Hz)
according to IEC
61000-4-8
3 A/m
3 A/m
Power frequency magnetic fields
should correspond with the typical
values that can be found in the
commercial or hospital environment.
NOTE U
T
is the A.C. mains voltage prior to application of the test level.
