-WARNING-
Do not remove the scanner from the surface before stop-
ping the recording or setting a marker. Failure to do this
may result in incorrect or misleading measurements. For
information on setting a marker, refer to section 7.2.5.5.
This symbol may appear when the scanner is being
moved over the surface. It indicates that the scanner is
being moved too fast and it is unable to process all the
signals generated. The maximum scanning speed is
0.5 m/s. If the symbol is displayed while recording a
Quickscan, press the
Confirm button . You will need to
begin the recording operation again from the original
starting point or from where the last marker was set.
The data may be transferred to the monitor. Refer to sec-
tion 7.4.
7.2.5.4 Quickscan settings
The Quickscan settings are shown on the left hand side
of the display. The settings can be made before making
a Quickscan or a Quickscan with accurate depth mea-
surement. Use the
Arrow buttons and Confirm to access
the setting.
Minimum depth
Use this setting when scanning a surface and looking
specifically for bars that are located above a certain
depth. For example, if checking for 40 mm minimum
depth of cover, set the value to 40 mm. (For quality
assurance measurements add an extra 2 mm to account
for any accuracy limitations). The LED will light only if
a reinforcing bar lying within 40 mm of the surface is
detected.
Select the minimum depth function using the Arrow
buttons and then press Confirm .
Setting minimum depth
Minimum depth function disabled
When the value is set to 0, the function is deactivated
and appears as above. Enter the required minimum depth
using the
Arrow buttons . Press Confirm to make the
setting. The system returns to the main menu.
Scan direction
This setting is used to set the direction in which Quick-
scan recording is performed. Although it has no direct
effect on any measurement values subsequently con-
tained in the monitor or PC application, it helps to match
the resulting chart and depth values in the PC applica-
tion with the actual structure surface. The scan direc-
tion will be saved with all Quickscan recordings.
Select the direction in which the scan is to be performed
and press
Confirm .
Bar diameter
This setting must be made in order to be able to mea-
sure depth of cover accurately, or to allow values to be
recorded. Only then can depth be measured accurately.
Select the Bar Diameter function using the Arrow but-
tons . Press Confirm.
If no bar diameter is selected, the scanner will calculate
the depth as though the average bar diameter of the rel-
evant standard setting range were set.
