Compliance level
±6 kV contact
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic
±8 kV air
material, the relative humidity should be at
least 30 %.
± 2 kV for power
supply lines Mains power quality should be
that of a typical commercial or
± 1 kV for hospital environment
input/output lines
± 1 kV differential
mode Mains power quality should be
that of a typical commercial or
± 2 kV common hospital environment
mode
5 % UT
(>95 % dip in UT)
for 0,5 cycle
40 % UT Mains power quality should be that of a
(60 % dip in UT) typical commercial or hospital environment.
for 5 cycles If the user of the Audiometer 9910 requires
continued operation during power mains
70 % UT interruptions, it is recommended that the
(30 % dip in UT)
for 25 cycles
Audiometer 9910 be powered from an
uninterruptible power supply or a battery.
<5 % UT
