5. Measuring Procedures
(1) Hold the hook on the main unit and take out the sensor and display panel from the case. The
case opens at angles of up to 180° at which a stopper prevents further opening. Do not forcibly
open it more than 180°.
(2) Select the unit of wind velocity and temperature.
Press the UNIT/MODE key while the device is turned off. Select a desired unit set from the
eight unit sets shown below. Each time this key is pressed, the unit set is cycled as follows.
When the desired unit set appears, wait for approximately 12 seconds and do not press any key
until the unit set is registered.
°C MS : meter per second °C KMH : Km per hour
°F KNT : knot °C KNT : knot
°F BF : Beaufort wind scale °C BF : Beaufort wind scale
°F FPM : feet per minute °F MPH : mile per hour
(3) Press the ON/OFF key to turn the power on. Make sure that the selected units of measurement
light on the display panel.
(4) Orient the probe in the direction of wind flow. Set the probe so that wind is flowing from the rear
surface of the probe (the serial number is on) to the front surface (the LCD is on).
(5) When the approximate direction of wind flow is determined, wait at least two seconds for the
measured values to stabilize before reading them.
(6) Upon completion of measurement, press the ON/OFF key to turn off the power.
If none of the function keys are pressed for approximately 20 minutes, the auto power-off
function will be activated, causing the power to shut off automatically. Make sure that the
operation interval will not exceed 20 minutes when continuous measurement is to be
performed.
Caution
- If the device is used in an atmosphere of high wind velocity (beyond the measurement range), or a
measurement is taken while holding the unit out of an automobile window while driving, the
vane (propeller) may be damaged. Do not use the device in such a manner.
- Measurement outside the specified measurement range is not guaranteed (see the accuracy
table). It may result in failure or damage of the device.
- To assure measurement accuracy, set the probe at right angles ±5º to the direction of wind
flow. The measurement accuracy will decrease if the angle exceeds ±5º.
