6. Measuring Surface Velocity
6.1 Introduction
To begin a velocity measurement, point the radar gun at the water
and pull and release the trigger (there is no need to hold the trigger
in) . The surface velocity can be measured flowing toward or away
from the gun . A dash ( - ) on the left hand side of the display (as
seen in Figure 6) will show and continue to flash until the velocity
stabilizes .
The dash will stop flashing when the SVR™ has performed enough
measurements to display an averaged and reliable velocity . The SVR™
will begin taking an additional 10 measurement starting with zero
(0) and proceeding up to 9 as each measurement cycle is completed .
Once all additional 10 measurements have been completed the
average of all the measurements are displayed . This will take 60
seconds to complete .

6.2 Taking a Measurement
• Turn the SVR™ on by pressing the PWR button. Once the display
segment check is completed the gun is ready to use .
• Pull and release the trigger. The SVR™ shows a dash ( - ) on
the left hand side of the display . The dash ( - ) keeps flashing,
indicting SVR™ is taking measurements . The velocity is updated
once per second . This velocity may vary significantly while the
