THIS TOOL EMITS LASER RADIATION.
DO NOT STARE INTO BEAM.
AVOID DIRECT EYE EXPOSURE.
ATTENTION IMPORTANT
• Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as the laser beam
could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally stare into the
laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or flammable liquids.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as serious eye
injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the battery when storing the tool for an extended time (more than 3 months)to avoid
damage to the tool should the batteries deteriorate.
• Do not attempt to repair or disassemble the laser tool. If unqualified persons attemptto repair this
tool, warranty will be void.
Range is specified between a minimum 2-inches to a maximum of
165-feet with an accuracy of 1/16”. Longer ranges will be found by the
instrument but a variance in the accuracy may exist. At night or dusk
the range may be greater than during daylight or if the target has poor
reflective properties.
Target Surfaces
Measuring errors may occur when aiming at surfaces composed of
colorless liquids (e.g. water), glass, Styrofoam or similar semi-permeable
surfaces. Aiming at high gloss surfaces may deflect the laser beam and
lead to measurement errors.
Hazards of Use
Be aware that errors in distance measurements may occur if the
instrument is defective or has been dropped, been misused or modified.
Note
Conduct periodic test measurements to ensure the instrument is measuring
accurately and consistently. This is most important if the instrument has
been exposed to abnormal use. Always confirm accuracy before and
during important measurements. Keep the laser distance measure optic
clean and inspect for damage.
4. Replace battery when the
flashes on screen. When this icon
appears there are approximately 100 measurements remaining.
Note
Use only alkaline batteries. If the instrument will not be used for an
extended time, remove the batteries to protect against corrosion.
Power Button
Press and release Power Button to power up.

This laser distance measure has the capability to add or subtract area,
volume or indirect measurement calculations. For example, if you need
the square footage of four rooms this instrument will allow you to add
each area calculation together to sum the dimensions of the four rooms.
The same holds true for volume or indirect measurement modes.
Please see each respective measurement section for the step-by-step
instructions.
This mode will take continuous measurements
as you move closer or further away from the
target. Minimum working range is 2-inches.
Maximum working range is 165-feet.

Note: For accurate measurements the instrument’s position must be held
constant. For example, note the position of your hand when
taking first measurement. Do not move your hand when preparing to take
the second measurement. Simply pivot your wrist (keeping
instrument in same position) to align the next target. Then record
next measurement.

This model is designed to take measurements indoors under normal
settings. The measuring surfaces and ambient light are critical factors to
the quality of measurement (indoors and outdoors). Outdoor measurement
capability may be limited due to sunlight/UV ray interference. Please note
that in some situations the unit may have difficulty reading the surface
you try to measure if lighting or sunlight is intense and/or the surface
being measured does not reflect the laser beam appropriately.
Measurement Errors
Error messages will appear if the unit’s receiver is not getting a
sufficient laser return signal.
Common surfaces that could cause an error reading:
- Water or other fluids
- Translucent to clear surfaces like glass or acrylic
- Porous or dark surfaces may require longer reading times or
cause an error reading
- Moving surfaces or objects such as curtains
- Highly reflective or angled surfaces may deflect the laser
beam signal
Check and verify value or
the sequence of
measurements is correct
Measure in an environment
within
specified working
temperature range
(shadow target)
Tips from the Pro’s
Take more than one measurement in critical situations where accuracy
needs to be greater than an estimation measurement. Take 3-4
measurements from the same position to compare consistency of each
reading. Prior to important measurements verify that the instrument is in
proper working order and take sample measurements of a known
distance to verify accuracy.
To accurately measure from the rear of the instrument, use a scrap piece
of drywall or other flat material. Extend the material off the corner and
butt the LDM up to the material. Then take measurement.
Place a white sheet of paper over the targeted measuring surface if error
message Err02 occurs to improve the return signal.
*The working range and accuracy is dependent on how well laser light is reflected
from the surface for the target and with increased brightness of the ambient light
intensity measuring accuracy may deteriorate.
