Understanding How the TruPulse Works
The TruPulse consists of a laser range sensor, an integrated tilt sensor, and a digital processor. The
TruPulse has three buttons that access the unit's internal software, which controls the integrated
sensors.
LCD Display
A liquid crystal display (LCD) is mounted within the optical system and when activated, displays a
reticle for targeting, yards / meters, and the display indicators. Inherent in the manufacturing process
are small black spots that appear in the optical system. These are a natural characteristic of the LCD
and cannot be fully eliminated in the manufacturing process. These small black spots do not affect
the distancing performance of the unit.
Laser Range Sensor
The laser range sensor emits invisible, eye safe, infrared energy pulses. The TruPulse determines
distance by measuring the time it takes for each pulse to travel from the rangefinder to the target, and
back. The LASER indicator is displayed whenever the laser is being transmitted. The laser may be
active for a maximum of 10 seconds. Once the target is acquired or the laser has timed out, you can
release the FIRE button. The TruPulse has a broad spectrum of sensitivity and can work with both
reflective and non-reflective targets. See TruTargeting (below) for information about high quality
and low quality targets.
TruTargeting
The TruPulse automatically provides the best accuracy and acquisition distance to a given target.
Maximum measurement distance varies with target quality and environmental conditions. When
shooting to a non-reflective target, the maximum measurement distance is approximately 1,000
meters (3,280 feet). When shooting to a reflective target, the maximum measurement distance is
approximately 2,000 meters (6,560 feet).

Section 1 - Introducing the LTI TruPulse 200
Page 5
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.
oAccuracy: ±1 yd (±1 m).
•120.0 feet (meters / yards) indicates a measurement was made to a high quality target.
oFeet are shown in half-unit increments (.0 or .5).
oMeters and Yards are shown in tenth-unit increments (.0 - .9).
oAccuracy: ±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.
