Section 1 - Introducing the LTI TruPulse 200

When selecting a target, you should consider the following:
• Color: The brighter the color, the longer the range.
• Finish: Shiny finishes provide longer range than dull finishes.
• Angle: Shooting perpendicular to a target provides better range than shooting to a target
at a sharp angle.
• Lighting Conditions: Overcast skies will increase the unit's maximum range, and sunny
skies will decrease the unit's maximum range.
Target quality has an effect on the precision of measurements. A high quality target will result
in a measurement that includes one decimal place (tenths). A low quality target will result in a
measurement that is a whole number.
Examples:
• 120 feet (meters / yards) indicates a measurement was made to a low quality target.
o Accuracy: ±1 yd (±1 m).
• 120.0 feet (meters / yards) indicates a measurement was made to a high quality target.
o Feet are shown in half-unit increments (.0 or .5).
o Meters and Yards are shown in tenth-unit increments (.0 - .9).
o Accuracy: ±8 inches (±20 cm).
Only International lasers include meters.
Tilt Sensor
The integrated tilt sensor measures vertical angles that the TruPulse uses to calculate height and
elevation and to determine slope-reduced horizontal distances. The instrument held level is at 0
,
and is rotated up through +90
, and down through -90
.
• The laser is not active in the Inclination (INC) Measurement Mode.
• Generally, the inclination is measured when you press
. However in
(1) the Continuous Target Mode and (2) in the Height Measurement Mode,
the inclination reading appears in the Main Display and the display updates
as your aiming point changes as long as you press
. In these two situations,
the measured inclination is based upon the aiming point when you release
.
Digital Processor
The TruPulse includes LTI's proprietary ASIC chip (Application-Specific Integrated Circuit).
The ASIC chip combined with high-speed CPU processing allows the TruPulse to deliver
accurate and fast measurements.
