Measurement environment
Metallic objects should not be present within a radius of one meter
around a measurement point, such as:
Manhole covers
Drains
Road restraint systems (crash barriers)
Other reflectors
Cars, construction machinery
Strong electromagnetic fields (caused for example by radar systems,
radio masts, underground cables) in the environment of a measuring
point can influence the measuring accuracy. The influence depends on
the strength of the source and the distance to it. If it is suspected, that
strong electromagnetic fields are located near to a measuring point,
several measuring runs should be carried out at this measuring point.
If the deviation of the individual results is higher than the specified
device tolerance, this can be an indication of the influence of
electromagnetic fields on the measurement signal.
Wearing safety footwear such as steel-toed boots has no influence on
the measurement as long as they are not too close to the probe.
