General handling instructions
Moving the instrument rapidly
in an
electrostatic field can have a disruptive
influence. The effects of this have been
minimized in the ESM “RadMan” by means of
special construction features. Despite this,
moving the instrument very quickly can
produce field strengths that are too high by
several V/m.
Tip:
Hold the ESM “RadMan” as still as
possible to make accurate
measurements.
In the immediate vicinity
of a weak
transmitter such as a cell phone, the alarm
threshold can be exceeded locally without any
actual risk arising. The standards
implemented in the ESM “RadMan” are based
on full-body exposure in a far-field. (Special
standards apply to near-field measurements,
e.g. on cell phones.)
Tip:
Check whether the alarm persists at a
minimum distance of 30 cm from the
field source or from secondary
radiators.
