1. Press POWER to turn the meter on .
2. Continuously press FUNCTION until the meter displays
the wind-speed and ambient temperature measuring units
(ft/min, m/S, km/h, MPH, knots, °C, °F).
Because the anemometer readings are taken while
holding the meter upside-down, the values display upside-
down on the LCD (180° from the other function displays).

to select the desired wind-speed measuring unit.
4. Press
°C/°F

Fahrenheit (°F) temperature reading.
5. Ensure that the air flow sensor is free from obstruction and
face the air-flow sensor in the direction of the wind.

temperature of the surrounding environment and displays
the value.
