To achieve this, we provide the tripod horizontal extension (WSNA0002). The
ber optic connection could also support in keeping the user farther from the
device. See accessories in Appendix 9.
Appendix 6. E-eld Measurement under Powerline
When measuring electric eld below a power line, it is advisable to place the
SMP2 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 eld measurements using the WP400 and WP50
probes, the body should not be close to the device. A person holding the
device during measurement would perturb the eld. 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.
