Interference resistance
tests/standard
Conducted HF interference
according to
IEC 61000-4-6
Radiated HF interference
according to
IEC 61000-4-3
Notes:
NOTE 1: The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2: These guidelines may not be applicable in all cases. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
The field strength of stationary transmitters such as base stations of mobile telephones and mobile radio devices,
a)
amateur radios, AM and FM radio and TV transmitters cannot be theoretically determined precisely in advance. In order
to determine the electromagnetic environment with regard to the stationary transmitters, an investigation of the
electromagnetic phenomena at the site should be considered. If the measured field strength at the location where the
CURIS flow Irrigation pump is used exceeds the aforementioned compliance levels, the irrigation pump should be
®
monitored to confirm it is functioning as intended. Should unusual performance characteristics be observed, additional
measures may be required, such as changing the alignment or location of the CURIS
The field strength should be less than 3 V/m across the frequency range of 150 kHz to 80 MHz.

separation distance that is calculated
according to the equation suitable for
the transmission frequency.
Recommended separation distance:
d = 1.2√ P for 80 MHz to 800 MHz
d = 2.3√ P for 800 MHz to 2.5 GHz
Where P is the maximum output
power rating of the transmitter in
watts (W) according to the transmitter
manufacturer and d is the
recommended separation distance in
meters (m).
According to an inspection on site
the field strength of stationary radio
transmitters should be less than the
