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 attempt
to repair this tool, warranty will be void.

Measuring Reference
Range
Range is specified between a minimum 2-inches to a maximum of
230-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.

Indirect Measurements ( ythagorean Methods)
All Calculations are based on Pythagorean Theorem a2+b2=c2.
This function allows for the measurement of hard to reach jobs.
Follow the order of the flashing lines for each required measurement.
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.

Indoor & Outdoor Measurements
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 an 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.
Backlight
Press and hold the button for two seconds
to activate backlight. Repeat this step to turn off
backlight.

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
Error Codes

Tips from the ro’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 to 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.
