Welcome to Decatur Electronics, Inc.
Thank you for choosing this Decatur Electronics product—the
SVR3D™, an advanced surface velocity radar (SVR) device for
measuring water surface velocity. The SVR3D is extremely
valuable for measuring watersurface velocity during high-velocity
flows and flood conditions where using contact measurement
instruments poses a risk to safety.
The SVR3D incorporates many leading features such as cosine
error correction for the vertical and horizontal angle positions of
the gun to the target
.
The SVR3D also contains a configurable
horizontal cosine adjustment that may be used when the angle of
the gun is notparallel to the flow of the target
.
If you are as pleased with its performance as we think you will
be, ask your Decatur sales representative about other Decatur
productsincluding the Genesis™ line of radars, the Onsite™
line of speed trailers, dollies, and pole signs.
Try any one of our products and see if you don't agree that it
is thebest-in-class!

Note the following symbols in this manual:
Indicates a warning message about
safety
precautions.Please read carefully
.
Indicates a helpful tip or precaution to note
.
This manual contains valuable information to help you set up,
use and maintain your radar, so you can optimize its life and
keep it atpeak performance. Please take a moment to read
through it, and keep it handy for future reference.
All service needs should be referred back to the manufacturer.
•The internal battery pack is not user serviceable.
WARNING
Do not put the radar gun in the water. This will
damage it. The SVR3D measures the water
surface only
from outside the water.

•Opening the SVR3D
automatically voids any
warranty still in effect. There
are no user serviceable
parts inside.
•
Do not expose the SVR3D to excessive moisture.
Never
submerge the device. If the SVR3D should
accidentally
get submerged, remove from the
water immediately, wipe off and let dry.
•Do not drop the SVR3D on hard surfaces since
damage
could occur. Units damaged by dropping or
abuse are not covered for warranty repair.
Violation of
these
guidelines
may
void
the
warranty.

•When you receive your radar, inspect all components for
freight damage that might have happened during shipping
or
unloading. Take pictures to document any damage.
•Notify the freight company immediately of any damage,
preferably while the driver is present. Record the damage on
thebill of lading and keep a record of the problems or
damage.
•The package should include the following pictured items
alongwith this User’s Manual.

3.1 Introduction
The SVR3D is a hand-held surface velocity radar (SVR™) gun
specificallydesigned to measure the surface velocity of water—
great for use in streams and rivers. Features such as Recall
allows you to review the previous measurement. Other features
are selectable through the menu option.

The radar gun features a tilt sensor system, which internally
compensates for the cosine angle effect of the vertical (pitch-
down)
angle of the gun to the target. It is not necessary to
manually set the
tilt sensor.
3.2 Battery Charging
The SVR3D contains an internal Lithium rechargeable battery
pack
.
When you first
receive your radar, the batteries will need
to be charged for the first
time before using. Once batteries have
been
charged
if
you
do
not
use the SVR3D for 3-4 weeks, you
will want to recharge the batteries
before use in order to get the
full run time
.
To charge batteries for the
first
time, follow steps in

3.3 Charging the Batteries
The USB power cable that comes with the SVR3D is used to
charge the internal battery.
P
lug the USB cable into the USB
connector located near the front of the trigger. The USB
connector can be inserted in either orientation. If the SVR3D is
powered off and charging, a green charging status light will
illuminate the center power button. Once fully charged, the
green light will stop lighting. If the SVR3D is powered on,
battery charge and charging status will be shown in the upper
right hand corner of the display.
