Range Selector Switch
By turning the switch, the following measuring ranges can be
selected: electric field in V/m (Volt per Meter)
• 0 - 200 V/m
• 0 - 2000 V/m
Filter for Frequency Analysis
The frequency filter module built into the E-Field 1 is is especially
optimized for the needs of structural biology.
It includes the following switch positions:
1. 10Hz to 400kHz = full bandwidth,
2. 16Hz = Band pass filter for the frequency of
railway current
3. 50Hz to 400kHz = High-pass filter for power
and its harmonics
4. 2kHz to 400kHz = High-pass filter, for the so-
called "artificial" harmonics above 2
Kilohertz. This frequency range corresponds
to the volume 2 of the TCO standard.
