AIR VELOCITY MEASUREMENTS

Measurement Range
0.0 TO 45.0 m/s (Meters per second)
0.0 TO 140.0 km/hr (Kilometers per hour)
0.0 TO 100.0 mph (Miles per hour)
0 TO 8800 ft/min (Feet per minute)
0.0 TO 88.0 knots (Nautical miles per hour)
Accuracy: ±2% for all ranges
BATTERY INSTALLATION:
Unpack the Anemometer with care.
Open the battery door and install 3 "AAA" batteries into the battery compartment.
Close the battery door.
Replace batteries when the Low Battery Indicator appears on the screen.

PRODUCT OPERATION:

ON/OFF
Press "ON/OFF" for ON/OFF Switching. Full display will show. The upper display
shows the velocity (default as m/s) VELO sign, while the lower display shows the
temperature (default as °F) measured.
ONE HOUR AUTO POWER OFF FUNCTION & CANCELLATION:
Product will turn off automatically after one hour. To disable this function, press
"ON/OFF" and "H/T" together each time the unit is turned on. The product will
remain "ON" until being shut-off by the user.
UNIT
The unit default is in ft/min for air velocity. Pressing the UNIT button cycles as
follows: ft/min > mph > m/s > km/hr > knots.
HOLD-TEST
Press the HOLD button to freeze the reading for recording (both velocity and
temperature), HOLD sign appears. Press again to return to real time mode.
°F/°C
Press °F/°C button to switch between °F and °C.
