Electrical field
The microscope is a class A device (industrial). The microscope is de-
signed to operate in a controlled electromagnetic environment. This
means that devices with RF transmitters such as mobile phones or
DECT phones must not be used in close proximity.
Vibrations
Horizontal vibrations (in x/y-direction)
Up to 10 Hz: less than 5 μm/s
10–60 Hz: less than 10 μm/s
Above 60 Hz: less than 14 μm/s
Vertical vibrations (in z-direction)
Up to 10 Hz: less than 4 μm/s
10–60 Hz: less than 14 μm/s
Above 60 Hz: less than 20 μm/s
Magnetic stray
fields
Measured in time domain and at specimen chamber height (1.0–
1.5 m).
DC component: 0.5 mG / 5 min or less
AC component: less than 1 mG peak to peak between 10 Hz and
1 kHz
Acoustic noise
Up to 120 Hz: less than 52 dB
120–450 Hz: less than 43 dB
Above 450 Hz: less than 47 dB
