Appendix 6. E-field Measurement under Powerline
When measuring electric field below a power line, it is advisable to place the
SMP3 in horizontal and and be separated from the unit with a tripod or a
wood stick or extension.
In high frequency measurements, placing the device horizontally will
increase the LF (low frequency) immunity and obtain more accurate results.
For low frequency electric field measurements using the WP10M, WP400 and
WP50 probes, the body should not be close to the device. A person holding
the device during measurement would perturb the field. It is therefore advised
that the user places the device at a horizontal position and stays away from
the device (1.5 m minimum, 3 m recommended as per IEC 62110) to obtain
more accurate (unperturbed) results.

To achieve this, we provide the tripod horizontal extension (

). The
fiber optic connection could also support in keeping the user farther from the
device. See accessories in Appendix 9.
