MEASUREMENT NOTES
MEASUREMENTS
Barometric Pressure Trend
: indicates pressure is rising quickly (>
+0.18 inHg) in 3 hours
: indicates pressure is rising (within +0.06
and +0.18 inHg)
: indicates pressure is stable (remains
between -0.06 and +0.06 inHg)
: indicates pressure is dropping (within
-0.06 and -0.18 inHg)
: indicates pressure is falling quickly (>
-0.18 inHg)
Water and Snow Temperature
The Kestrel Meter may also be used
to measure the temperature of water
and snow. Submerge the thermistor
portion (curly exposed wire in window
next to impeller) in water or snow
to get an accurate reading. Kestrel
Meters are completely waterproof
and can be safely submerged in water
according to IP-67 standards (up to 1
meter for a maximum of 30 minutes).
Backlight
• Press to activate the backlight for 10
seconds.
• Press again to manually deactivate
the backlight before 10 seconds expire.
Compass Accuracy
The accuracy of the compass can be
aected by:
• Compass calibration: Refer to
calibration instructions.
• Local magnetic elds: Metal
objects and devices emitting
electric signals may inuence the
compass accuracy.
• Rapid Movements
Conrm that the accuracy of the compass
in the measurement environment is suitable
for your purposes.
