Precautions
Avoid staring directly at the laser beam for prolonged periods.
The TruPulse® 200L is designed to meet FDA eye safety requirements and is
classified as eye-safe to Class 1 limits, which means that virtually no hazard is
associated with directly viewing the laser output under normal conditions. As
with any laser device, however, reasonable precautions should be taken in its
operation. It is recommended that you avoid staring into the transmit aperture
while firing the laser. The use of optical instruments with this product may
increase eye hazard.
Never attempt to view the sun through the scope.
Looking at sun through the scope may permanently damage your eyes.
Never point the unit directly at the sun.
Exposing the lens system to direct sunlight, even for a brief period, may
permanently damage the internal components.
Avoid direct sun exposure on the eyepiece.
Exposing the eyepiece to direct sunlight can damage the internal display.
Do not expose the instrument to extreme temperatures.
TruPulse® 200L components are rated for a temperature range of -4 to +140° F
(-20 to +60° C). Do not expose the instrument to temperatures outside this
range whether in use or in storage.

Understanding How the TruPulse 200L Works
The TruPulse 200L consists of a laser range sensor, an integrated tilt sensor, and a digital
processor. The TruPulse 200L has three buttons that access the unit's internal software,
which controls the integrated sensors.
Laser Range Sensor
The laser range sensor emits invisible, eye safe, infrared energy pulses. The TruPulse
200L determines distance by measuring the time it takes for each pulse to travel from the
rangefinder to the target, and back. The indicator is displayed whenever the laser is
being transmitted. The laser may be active for a maximum of 5 seconds. Once the target
is acquired or the laser has timed out, you can release the FIRE button. The TruPulse
200L has a broad spectrum of sensitivity and can work with both reflective and non-
reflective targets.
Targets
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.

Section 1 - Introducing the LTI TruPulse 200L
Page 5
Tilt Sensor
The integrated tilt sensor measures vertical angles that the TruPulse 200L 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 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 200L includes LTI's proprietary ASIC chip (Application-Specific
Integrated Circuit). The ASIC chip combined with high-speed CPU processing
allows the TruPulse 200L to deliver accurate and fast measurements.

Section 2 - Quick Start
1. Install the batteries (page 7).
2. Press to power ON the TruPulse 200L.
3. Select a target such as a tree or a building. For this
example, the target should be approximately 250 feet
(82 yards or 75 meters) from you.
4. Look through the eyepiece (see Figure #2) and use the
crosshair to aim to the target. The in-scope LCD should
look similar to Figure #3A.
oIf the indicator is not displayed, press
or until the indicator is
displayed.
5. Press-and-hold . The indicator is
displayed while the laser is active (Figure #3B).
The laser will remain active for a maximum of
5 seconds while acquiring data about the target.
oIf the target is not acquired, release
and repeat this step.
6. Release once the distance is displayed
(Figure #3C). The measurement will be
displayed steady until you press a button
or the unit powers OFF.
oPress or to scroll through the
measurement modes and see the results
acquired for each function.
oRepeat steps #3-#6 above to take another
measurement.
oSimultaneously press-and-hold and
for 4 seconds to power OFF the
TruPulse 200L.

Battery
Installation
The TruPulse 200L is powered by a 3 Volt Lithium battery commonly referred to as
CR123A or also referred to as CR123.
1. Remove the battery compartment cover by gently pressing the clip to release the
cover.
2. Install the battery as shown in Figure #4A. The battery must be oriented (+/-) as
shown in the figure and also on the indication sticker found inside the battery
compartment.
3. Replace the battery compartment cover by aligning the tab located on the top the
cover with the grooved edge of the battery compartment, and press the cover until
the tab locks into position.
Low Battery Warning
The TruPulse 200L monitors the incoming battery voltage.
Figure #5 shows the location of the battery status indicator.
•When the voltage drops below 2.6V, the BATT status
indicator flashes every 5 seconds, alternating with the
normally displayed information.
oYou should replace the batteries as soon as possible.
•When the voltage drops below 2.4V, the BATT status
indicator stops flashing and is displayed steady. At this
point, system operation is locked.
oYou must replace the batteries to return to normal
system operation.

Display Indicator Test
To verify that all display indicators are working properly:
1. Start with the TruPulse 200L powered OFF, press-and-hold .
2. Compare the in-scope display to the Figure #6 (page 9) to verify that all indicators
are working properly.
3. Release to start normal operation.
Error Codes
Error conditions can occur in a measurement or in the system
hardware. To make sure that you never get an erroneous measurement,
the TruPulse 200L monitors both system hardware and measurements.
When the instrument detects an error condition, it displays and error
code instead of a measurement.
Error codes appear in the main display and are in the form of “Exx”,
where “xx” is an error code number. Figure #7 shows an example error
code, E36.
If an error code persists:
1. Release and press again to try to retake the
measurement.
2. Remove and re-install the batteries and then try to retake
the measurement.
3. If the above steps do not resolve the error, contact LTI or
an Authorized LTI Distributor for assistance. Refer to the
inside front cover for LTI contact information.

Notes about Measurements
Press or to scroll through the individual measurement functions
and see the results acquired for each function.
•Both inclination and distance are measured in the
Horizontal Distance , Slope Distance , and
Vertical Distance modes.
•Example Range Measurement: = 12.5 meters
= 1.6 meters
= 12.6 meters
= 7.3 degrees
•When you scroll to the Height Function , the Main Display
will be blank and the will be flashing.
•In the Inclination Mode , the Main Display will be blank for
all other measurement functions since the laser is not active when
measuring inclination only.
•The last measurement does not need to be cleared before
acquiring your next target.
•Each time the TruPulse 200L is powered ON, it will return to the
same measurement mode that was last used.
Inclination Measurements
The laser is not active in the Inclination 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 .
Percent Slope
Percent slope, indicated by , is a calculation equal to 100 times the tangent of the
inclination angle. It is a variant way of expressing the inclination. You can get percent
slopes only in the basic measurement displays, never in the Height measurement displays.
Note also that the instrument never downloads a percent slope. It always downloads the
inclination angle.
An inclination angle of 5 degrees for example is equal to a slope of
about 8.75 percent.
