5.2.3 System Parameters
The following items are key parameters that must be set prior to and during the survey. These will
enable 440 to find the position of the target. To carry out an accurate survey, these parameters must
be entered correctly. To edit these settings, select Configuration
Figure 5-3: System Parameters
To follow we have listed some key parameters that will be required to be set prior to and during the
survey.
5.2.3.1 Target Scaling
Configure the 440 SEP with the following target information:
❐
Set the target diameter.
Measure the outside diameter of the conductive part of the target. Do not include any non-con-
ductive coating in the measurement of diameter. This value, together with the target scaling is
used to compute range.
❐
Weight coating.
Enter the thickness of any non-conductive weight coating that surrounds the target. DeepView
for Windows will allow for this thickness when it displays measurements of target co-ordinates.
DeepView for Windows uses a specially developed algorithm to determine an appropriate target
scaling factor based on the diameter of the target. For most applications this is the correct method to
use for setting a target scaling factor.
The target scaling value is designed to be as close as possible to that used for the previous 340
System. However for maximum accuracy, it is recommended that you have Teledyne TSS determine
an exact target scaling factor from a sample of your target.
