TEMPERATURE COMPENSATION:
Because temperature affects the speed of sound,
the SONIN Model 10075 has automatic tempera-
ture compensation for reater accuracy. In order
to make the most of this feature, wait 1 minute for
each 1°F (2 minutes for each 1°C) of temperature
difference between cool and warm locations.
DISPLAYING TEMPERATURE TO IMPROVE
ACCURACY: Since temperature affects accuracy,
the SONIN Model 10075 is most accurate when
its internal temperature matches the air temperature.
To displ y temper ture: press and hold
key, then press key, the internal temperature
will appear on the display immediately (in °C when
m display units are selected or in °F if selected
display units are ft:in, ft:ft, yds).
To o back to measurement mode, press and
release key or press the measure key directly.
HINT: To speed equalization of the SONIN Model
10075's internal temperature versus air tempera-
ture, wave the unit back and forth in the air to
circulate room temperature air throu h the unit.
For additional information, see "Temperature" in
the section on Environment l Conditions.
LOW BATTERY INDICATOR:
Replace the battery when the BATT symbol appears
on the LCD.

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.
Temper ture - Your SONIN Model 10075 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 adjust to air temperature.
As lon as the internal temperature is equal to the
air temperature, accuracy is unaffected. Wait for
- 15 -
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 tempera-
ture 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 DISPLAYING
TEMPERATURE for instructions on how to obtain
a temperature measurement from your SONIN
Model 10075.)
Altitude/B rometric 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/ - 0.6" H (0.3 km/-
15mm H ) you are above sea level. Add 0.4% of
the measured distance for each 1000 ft/ +0.6"
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 .
