A stretch of up to 30 m (98 ft) in length can be recorded before it is necessary to transfer the data to the PSA 100
monitor or the PSA 55 infrared adapter. It is also possible to record several separate stretches (max. 10) that add up
to a maximum of 30 m (98 ft).
The data recorded can be transferred to the monitor for analysis ( see section 7.4.1).

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 measurement. Use the Arrow buttons and Confirm button to access
the settings.
Limited depth scan
NOTE
This measurement mode allows rebars to be located within a specified depth range.
NOTE
When using the tool in this mode, the preset depth must take a clearance distance from the rebar into account.
Minimum depth
Use this setting when scanning a surface and looking specifically for bars that are located within a certain depth. For
example, if checking for 40 mm (1.6") minimum depth of cover, set the value to 40 mm (1.6"). (For quality assurance
measurements add an extra 2 mm (0.08") to account for any accuracy limitations). A signal tone is emitted and the
LED lights only if a reinforcing bar located within 40 mm (1.6") of the surface is detected.
CAUTION
Before making a scan, check to ensure that the depth range restriction is set correctly or deactivated if this feature is
not required.
Use the Arrow buttons to select the minimum depth function and then press Confirm.
Minimum depth function disabled.
When the value is set to "0", the function is deactivated and appears as above. Use the Arrow buttons to enter the
desired depth value and then confirm the setting by pressing the Confirm button. The system returns to the main
menu.
NOTE
If reinforcing bars are located at depths greater than the minimum depth set, no signal tone is emitted and no LED
lights.
Scanning direction
This setting is used to set the direction in which Quickscan recording is performed. Although they have no direct
effect on any measurement values later obtained from the monitor or PC application, the settings help to ensure that
