INTRODUCTION
Thank you for purchasing General Tools & Instruments’
(General’s) LTM1 50 Ft. Laser & Tape Measure. The LTM1 is
designed to replace a conventional tape measure in the
hands of both DIYers and professionals. Its design adds an
optical distance measuring system with a laser pointer and
digital readout to the familiar housing of a conventional
heavy-duty tape measure.
The optical measurement system works by shining an
invisible infrared beam on a target, which reflects the
beam back to the tool. The time it takes the beam to return
is proportional to the distance to the target. A red laser
pointer is used only to aim the beam, and not to carry any
information. The LTM1’s laser range of 50 ft. makes it
suitable for most indoor measuring tasks and many
outdoor jobs as well. The LTM1’s conventional tape
measure is 16 ft. long and ¾ in. wide. It should be used for
measuring distances less than 10 inches, as well as
distances between targets on the same plane (two points
on a floor or wall, for example).
Why is the LTM1 better than a conventional tape measure?
•
It’s faster.
It takes much less time—and only one hand—
to hold the tool against a wall, aim at the opposite wall and
press the measurement button than it does—requiring both
hands—to secure one end of a conventional tape measure,
walk the other end to the far wall, write down the reading
and retract the tape. The longer the distance to be
measured, the more time saved. Using the laser, the average
measurement can be made up to 10 times faster than by a
tape measure.
•
It’s more accurate.
Thanks to precision optics, the LTM1
can measure the distance between any two points further
than 10 inches apart with ±1/4 in. accuracy and 1/16 in.
resolution. It’s impossible to get that level of precision from
a tape that can bend or sag. What’s more, it’s much easier
to read the LTM1’s digital display, which can be held at eye
level, than to read a conventional tape measure whose
position may make tiny hash marks hard to see.
•
It’s safer.
Because the LTM1 can measure distances from a
distance, it takes the risk out of routine but tricky tasks. For
example, it makes it unnecessary to stand on a stepladder
and reach to measure the height of a ceiling.
WHAT’S IN THE PACKAGE
The LTM1 comes on a blister-packed card along with:
• Two “AAA” Alkaline batteries
• A small Phillips-head screwdriver for opening the battery
