4.2 System scanning performance
For reliable scanning results, the following conditions
must be fulfilled:
– Concrete surface smooth and flat.
– Reinforcement not corroded.
– Reinforcement lying parallel to concrete surface.
– Concrete does not contain additives or components
with magnetic properties.
– Reinforcing bars lying within ±5° of right angle to
direction of scan.
– Reinforcing bars are not welded.
– Neighboring bars are of similar diameter.
– Neighboring bars are at a similar depth.
– Accuracy specifications are valid only for the first
layer of reinforcement.
– No interfering influences from external magnetic
fields or objects nearby with magnetic properties.
– Bars have relative magnetic permeability of 85-105.
– The scanner wheels are clean and free from sand or
grit.
– All 4 scanner wheels rotate on when scanner is
moved across the object to be scanned.
– Bars comply with one of the following standards
(depends on PS 200 Ferroscan system item number
printed on underside of original toolbox).

-WARNING-
If any one or more of these conditions are not fulfilled,
accuracy and precision may be compromised.
The ratio of bar spacing:cover (s:c) is often a limiting
factor in resolving individual bars.
This is defined as:
4.2.1 Detection range, measurement range and
accuracy
Minimum bar spacing of 36 mm (1.4 inches) for resolv-
ing individual bars or bar spacing:cover (s:c) 2:1, which-
ever is greater. A minimum depth of 10 mm (0.4 inch)
is required for a depth reading.
Minimum distance of nearest reinforcing bar from start-
ing point and finishing point of the scan (e.g. from edge
of reference grid): 30 mm (1.2 inch).
