Choose the required operating mode (cf. chapter "OPERATION").
„
As applicable, measure the radiation from a source of disturbance or the environment of a
„
disturbed instrument (B).
To do this, move the EF1 probe along the 3 perpendicular spatial axes (cf. chapter "MEASUREMENT
„
SENSOR") Fig.5. With probe EF2, simply point at the target to make the measurement.
As the field diminishes proportionally with distance, take care to place the extremity of the
probe as close as possible to the zone to be checked.
The operator must take care not to be between the source of disturbance and the zone to be
checked: the human body shields electromagnetic fields.
