2 Important Safety Instructions
16 SRM-3006 Narda
2.6 Dangers due to electromagnetic fields
WARNING
Strong fields
Very strong fields can occur in the vicinity of some radiation
sources
⇒ Be aware of and observe any safety barriers and markings.
⇒ In particular, persons fitted with electronic implants (e.g. pacemakers)
must keep away from dangerous areas.
WARNING
Unsuitable frequency range
Dangerous fields may not be detected if an unsuitable frequency
range is selected
⇒ Always select the largest available or the most suitable frequency
range.
⇒ Always carefully observe the actual measurement value display when
approaching unknown fields.
⇒ In case of doubt, use an additional wideband warning device such as
RadMan (XT) or Nardalert (XT) from Narda Safety Test Solutions.
WARNING
Misinterpretation of results when using single axis
antennas
When a single axis antenna is used, only the field components that
are parallel to the antenna axis will be detected. If the antenna is not
correctly oriented in the field, there is a danger that the field strength
value displayed will be low or even zero despite the presence of a
strong field.
⇒ Always use a suitable measurement setup when making
measurements with a single axis antenna.
⇒ Be aware of the polarization direction when aligning the antenna.
