After storage (tap

), the data can be seen in the Statistics View, the
Single-Line View, the Multi-Line View and also in the Snapshot View if at
least one diameter was measured (see “3.6 Review of Data”).
In the Multi-Line View the signal strength spectrum can be seen in addi-
tion to the cover and diameter, see “3.6 Review of Data”.
Area-Scan Mode
PM-630
PM-650
NOTE! It is advisable to locate the first and second layer re-
bars with the Locating Mode to find the optimum line posi-
tion prior to measuring in the Area-Scan Mode.
The Area-Scan Mode is mainly used to show the first layer rebar covers
on large areas, e.g. of concrete slabs in car parks. The measuring pro-
cedure is the same as for the Single-Line, respectively Multi-Line Mode.
The Area-Scan Mode is best suited for a combination with potential field
measurements; e. g. combined with Canin+ measurements. But in this
case the line height and grid width must be the same for both measure-
ments (square grid required by Canin ProVista).
• Enter the settings menu by tapping
5
.
• Set the correct settings as for the Single-Line and Multi-Line Mode.
Additionally the grid width must be set. It must be about 1.1 times
larger than the maximum rebar spacing of the first layer rebars. This
guaranties at least one rebar located within one grid.
NOTE! Since the Area-Mode is used on rather large areas,
“Return to start on new line” should not be set.
The measuring procedure including turning the probe cart and changing
cursor position is the same as for Multi-Line Mode.
Figure 12 is a plan view, where the cover values are shown as rectangles
of different colors. Red means the cover is smaller than the minimum set.
A cover will only be shown up to 90 % of the cover ranges indicated in Figure 2.

After storage (tap

), the data can be seen in the Statistics View, the
Multi-Line View and also in the Snapshot View if at least one diameter
was measured (see “3.6 Review of Data”).
Cross-Line Mode
PM-650
NOTE! It is advisable to locate the first and second layer re-
bars with the Locating Mode to find the optimum line posi-
tion prior to measuring in the Cross-Line Mode.
The Cross-Line Mode is mainly to display the rebars of the first and sec-
ond layer arranged in a rectangular mesh. The measuring procedure in-
cluding turning the probe cart and changing cursor position is the same
as for Multi-Line Mode. In fact it is a Multi-Line scanning in X- and Y-
direction. In addition to the Multi-Line settings the grid width to define the
space among the Y-lines must be set. If “Align Rebar Positions” is set,
it will affect the Cross-Line views Cover and Diameter only. The view of
Signal Strength remains unchanged.
