Appendix
Guidance and manufacturer's declaration - electromagnetic immunity
The "Bluephase Meter" is intended for use in the electromagnetic environment specified below. The customer or the user of the "Bluephase Meter"
should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 V
rms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.7 GHz
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
Compliance level Electromagnetic environment - guidance
Portable and mobile RF communications equipment should not be used closer to any part
of the "Bluephase Meter", including cables, than the recommended separation distance
caculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
No cables connected to the device.
n.a.
d = 1.2 P 80 MHz to 800 MHz
3 V/m
d = 2.3 P 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).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey, a should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
"Bluephase Meter" is used exceeds the applicable RF compliance level above, the "Bluephase Meter" should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the "Bluephase Meter".
b Over the frequency range 150 kHz to 80 MHz, field strength should be less than 0 V/m.
