Getting Started: Recording Projectile Velocities
Getting a velocity is a simple as turning on the chronograph and shooting
over it. You must shoot along the long dimension of the chronograph,
within the triangle formed by the rods and the diffuser screens (even if
they are not installed), being careful not to hit any parts of the chronograph.
On detection of the projectile, the display will briey show the current shot
string and updated number of shots in the string, followed by the velocity
recorded.
Duplicate Velocities
If the chronograph should record 2
shots of the same velocity one after the
other, the “duP” (duplicate) message
will appear (Fig. 2), followed by a single
digit number representing the duplicate
velocity. If additional shot velocities are
also the same, the number will increment. If 10 sequential duplicate shot
velocities are recorded, the number will be reset to 1.
Low Battery Indication
If the battery voltage becomes low, the
chronograph will ash the word “bAt”
at intervals to signal that it is time to
change the battery.(Fig. 3) If the battery
voltage drops below approximately 6
volts, the low battery indicator becomes
inoperative.
Error Indication
In the event a signal is recorded by the
rst sensor, but no signal is recorded
by the second sensor, an error “Err”
message will ash momentarily.
(Fig. 4) You should try adjusting your
aim position if this occurs.
Working with Projectile Velocities and Statistics
The Pro Chrono Digital chronograph allows you observe and work with your
velocity data. This is done through the use of the front panel pushbutton
controls, described below. Competition Electronics offers two accessories as
another option for managing the chronograph functions and data remotely.
More information on the Digital USB Remote and Digital Remote Control is
found in the “accessories” section of this manual.
