8.2 Performance
The following tables show the results of tests performed by Teledyne TSS using 5 metre lengths of
sample targets. They illustrate the range and accuracy that you may achieve under ideal conditions by
following the procedures described in
Chapter 6 "Operating Procedure" carefully.
The charts show:
Horizontal axis the true lateral offset of the target relative to the centre-line of the coil array. Note
that the response of the coil array is symmetrical and accuracy is the same to port
and starboard of the centre-line
. The values are valid for positive and negative
lateral offset .
Vertical axis increments of increasing true vertical range to the target.
Data table the difference between the measurement of VRT shown on the 440 and the actual
vertical range.
IMPORTANT NOTE:
You should not use these charts as correction tables. They provide an indication
only of what you could achieve under ideal operating conditions if you follow the
correct operating procedures for the 440 System.
Note also that each table applies to one type and size of target only .
