However, we recommend that you do not leave
your SONIN unit in very cold or very hot conditions
(e.g. sunlight in a car), as the unit will then require
more time to adjust to air temperature.
Altitude/Barometric Pressure - Altitude and
barometric pressure can affect the range and
accuracy of all ultrasonic distance measuring tools.
As the Altitude increases (barometric pressure
decreases), the range is reduced. As altitude
decreases (barometric pressure increases), the
range is increased.
To correct for altitude (pressure) effects on accuracy,
subtract 0.4% of the measured distance for each
0.3 km/-15mm Hg (1000 ft/-0.6" Hg) you are
above sea level. Add 0.4% of the measured
distance for each 0.3km/+15mm Hg (1000 ft
+0.6" Hg) you are below sea level (Sea Level =
760mm Hg).
Noise - High frequency noise from machinery,
engines, computers, stereos, TV sets, etc. can affect
the reading and you may get random readings.
Stand away from or shut off this type of equipment
when measuring.
Outdoor Measurements - Your SONIN 45 is
