Figure 12: Single-Line option to mask a rebar by double-tapping on it
When utilizing the Single-Line Mode, the user has the option to display
the Cover curve, Signal Strength curve or no curve. The Signal Strength
curve is used to confirm the presence of reinforcing bars. Local effects
such as metallic elements present below the surface (metallic wire, anchor-
age, etc.) or changes in testing speed when obtaining the data can result
in an “apparent” reinforcing bar appearing on the screen. It is possible to
hide the “apparent” reinforcing bar by double tapping on the correspond-
ing dot when in Single-Line Cover or Signal Strength View and selecting
the “Mask” option. The corresponding cover values will not be taken into
account in the Statistical View (refer to Section “3.2.3. Cover Meter Display
Views”).
The path length measurement accuracy depends on the test surface. The
accuracy of measurements done on a smooth concrete surface (concrete
poured in metallic shuttering) is shown in the specifications, see “7. Tech-
nical Specifications”. On rougher surfaces the measured length may be
reduced or checked at certain intervals by setting markings on the test
surface and comparing with marks set on the display (long push on
A
).
After storage (tap

), the data can be seen in the Statistics View, the
Single-Line View and also in the Snapshot View if at least one diam-
eter was measured (see “3.2.3. Cover Meter Display Views”).
The maximum scan length is 999 m / 3’280 feet in each direction (to the
right and to the left from the zero line).

File name: enter the file name and tap return. Saved measurements
will be stored with this file name. If several measurements are made
under the same filename, a suffix increments after each measure-
ment and follows the file name.
