VISUAL ELEMENTS
RED line
- threshold level (value at the right is the digital
representation of the threshold level).
• This line is moved UP and DOWN when corresponding
▲
or
▼
buttons are pressed.
• Changed value is stored immediately as new threshold level for
current rifle profile.
• Range of the level is +/-100.
YELLOW rectangle
- this is the chart area.
WHITE grid lines
- +50 and -50 markers for measurement and
threshold level.
CYAN, BLUE, LIGHT BLUE vertical bars
- min/max representation of
the calculated differential value from acceleration sensor.
• Positive means weapon moving forward (away from the user).
• Negative means weapon moving backward (closer to the user).
• Various color represent the size of the bar - smaller, larger or largest.
• The bars might be offset to the zero line - this is so because the bar
represents the extreme positive and extreme negative accelerations
during period of 1000ms:
- the bottom end of the bar represents the extreme minimum of the
measured acceleration (e.g. -30);
- the top end of the bar represents the extreme maximum of the
measured acceleration (e.g. +25).

HOW TO SET THE THRESHOLD
• Start TRAINING mode.
• Perform one or more shots and observe the bars that represent
measured acceleration.
• Decide if negative or positive part of the bar (above or below the
zero line) is bigger.
• Set the threshold level. Move the red line by pressing
▲
/

buttons. Holding down
▲
/
▼
buttons will cause accelerated
movement of the line in 10 pixel increments.
• Press the center button to exit TRAINING mode.
NOTES:
• If you want to use the
positive acceleration
values as triggers you
should move the RED line above the zero (positive value), close to the
upper end of the bar.
Be sure to set the threshold a slightly below the bar top end - this will
provide margin to correctly detect shots with some variation in the
acceleration.
• If you want to use the
negative acceleration,
adjust the threshold
to be negative (below the zero line).
Be sure to set the threshold a slightly above the bar bottom end - this
will provide margin to correctly detect shots with some variation in the
acceleration.
• The margin from top/bottom end of the bars could be estimated
by observing variations of multiple shots - use the bar with weakest
acceleration to select the threshold level (again with some margin of
2-5 units) - e.g. if the weakest of multiple shots is read as 30 then set
the threshold to 25-27 to be sure that all shots will be recorded.
