Start/Kill Switch
The Start switch also has a deadman switch function. The FCC requires that when the operator
stops interacting with the system for ten seconds, the transmitter is to be shut off. This will also
close the data file that you have been acquiring. Thus, you will need to keep the Start switch on
the handle depressed at all times during data collection.
Note:
• Pressing Start one more time after you have collected a file will erase the previously
collected data.
• Print the data or transfer them to a PC if you wish to keep the record before collecting the
next line.
• The HandyScan can store 15 m (50 ft) of data. The unit will stop collecting data after this
amount has been reached. You will need to start a new file to resume collecting data.
• The HandyScan displays axes in metric units only, but the same data can be later displayed
using RADAN NT software on a PC in metric or English units.
Data Review
1. Use right/left arrow keys to scroll data.
2. Optimize data display:
• Press Gain until best display of features is achieved. Gain status is shown at bottom left
(Gain can be used during collection as well).
• Press PRCS, then up/down arrow to change processing method. PRCS method used is
shown
at bottom center.
• Use Set to modify display setup (contrast, amplitude, depth scale, etc.).
3. Label targets:
• Use arrow keys to move the cursors and locate targets. The cross-hair X (position) and Y
(depth) are displayed in the top left corner.
• Press Mark to label a target and display its X-Y along the right edge of screen (up to 7
targets).
Note: It is possible to transfer non-grid data to a PC and review them on the PC screen, taking
advantage of a higher quality display and (if installed) processing capability of RADAN
software. Please see Data Transfer (page 7) and RADAN manual for instructions on processing.
