held stationary.
Error 3
Math error or result overflow.
2) If you et readin s which are excessively lon or short,
the likely causes are:
a) The unit is not bein held parallel to the floor. Hold the
unit parallel to the floor and at 90° to the surface bein
measured to.
b) Measurin path is not clear of obstructions or it is not
wide enou h.
c) The surface you are measurin to is not sufficiently flat
and the sound waves are continuin to rebound. Place a
flat object, such as a board or mirror a ainst the surface
and measure to the object.
d) Environmental factors such as noise from machinery
or close proximity to an air conditioner or computer screen.
3) If you et readin s that are too short for the distance bein
measured, make sure there is a clear and sufficiently wide path
to the surface. Remove any objects in the way or select a
different surface to measure to.
4) If your laser does not display when takin a measurement,
it may be turned off. Check LCD to see if ( laser icon ) is
displayed. If it is not. press [2ND] and [RCL] to turn on laser.
1) If the LTRF is unable to take a " ood" measurement the
display will show one of the followin :
BLANK SCREEN

Measuring Distances Too S ort
Your measurin distance must be
lon er than 1 foot 5 inches from
top of unit or 1 foot 10 inches from
bottom of unit.
Error 1  Possible causes for
Error 1 include:
Measurement out of ran e or no
return si nal.
Unit is not perpendicular to the
surface.
Surface is not hard and flat.
Error 2  Possible causes for
Error 2 include:
No valid readin (Multiple object
detected).
5) Ran e and accuracy can be affected by environmental
factors such as wind, temperature, humidity and altitude (see
section on Environmental Conditions).
VERIFY TEMPERATURE TO IMPROVE
ACCURACY
Because temperature affects the speed of sound, the LTRF has
automatic temperature compensation for reater accuracy. In
order to make the most of this feature, verify the internal
temperature on the upper corner of LCD screen. If it does not
match the air temperature, wait 1 minute for each 1°F (or 2
minutes for each 1°C) of temperature difference between cool
and warm locations. See "TEMPERATURE" in the section on
Environmental Conditions.
Note: The temperature displays in °F when imperial modes are
selected, or in °C if metric mode is selected.
The minus si n - will alternately display with the readin
when the temperature is less than zero.
The readin 1 will separate and alternately display when the
temperature is over 100 °F.

ENVIRONMENTAL CONDITIONS THAT COULD
AFFECT PERFORMANCE
IMPORTANT
Ultrasonic Distance Measurin Tools work best for quick and
easy measurin and estimatin . They are not intended for
precision work, althou h they can be very accurate under
optimal conditions.
HUMIDITY
Humidity and temperature can affect the ran e and accuracy
of all ultrasonic distance measurin tools. They may ive
measurements that are lon er or shorter than their specifications
(dependin on atmospheric conditions). The ran e is lon est
in hi h temperature/hi h humidity and low temperature/low
humidity and ran e is shortest in hi h temperature/low humidity
and low temperature/hi h humidity.
Humidity effects on accuracy are reatest at hi h temperatures
and ne li ible at low temperatures. At 100°F (38°C) and 99%
R.H., the distance measurement will be short by 0.6%. At 100°F
(38°C) and 0% Relative Humidity, the distance measurement
will be lon by 0.6%. At 32°F (0°C) the distance measurement
will essentially not be affected.
TEMPERATURE
Your LTRF has unique automatic temperature compensation to
ensure consistency of measurements between 32°F and 100°F
(0°C to 38°C). The response rate of this circuitry enables you
to move between warm and cold areas and measure with
reasonable accuracy. However, we recommend that you do not
leave your SONIN unit in very cold or very hot conditions (e. .
sunli ht in a car), as the unit will then require more time to

DISCLAIMER:
The SONIN Laser Tar etin Ran e Finder employs a sonar
method of measurement. The laser pointer in this unit is for
reference purposes only, and is not part of the measurin
apparatus. The laser pointer indicates the approximate center
of the tar et area to which measured. The laser pointer neither
measures, nor increases the accuracy of measurement performed
by the unit usin sound waves. The accuracy of this measurin
device is 99.5% ±1/4" of the distance measured.
FCC NOTE
WARRANTY INFORMATION
adjust to air temperature. As lon as the internal temperature
is equal to the air temperature, accuracy is unaffected. Wait for
the unit's internal temperature to equal the air temperature or,
add 1% of the measured distance for each 10°F (5.5°C) that
the measured temperature is below the actual temperature;
subtract 1% of the measured distance for each 10°F (5.5°C)
that the internal temperature is above the air temperature. (See
section on VERIFY TEMPERATURE TO IMPROVE
ACCURACY for instructions on how to obtain a temperature
measurement from your SONIN Laser Tar etin Ran e Finder.)
ALTITUDE/BAROMETRIC PRESSURE
Altitude and barometric pressure can affect the ran e and
accuracy of all ultrasonic distance measurin tools.
As the altitude increases (barometric pressure decreases), the
ran e is reduced. As altitude decreases (barometric pressure
increases), the ran e is increased. To correct for altitude
(pressure) effects on accuracy, subtract 0.4% of the measured
distance for each 1000 ft/ -0.06" H (0.3 km /-15mm H ) you
are above sea level. Add 0.4% of the measured distance for
each 1000 ft/ +0.06" H (0.3km /+15mm H ) you are below
sea level (sea level = 760mm H ).
NOISE
Hi h frequency noise from machinery, en ines, computers,
stereos, TV sets, etc. can affect the readin and you may et
random readin s. Stand away from or shut off this type of
equipment when measurin .
