Hand-Held Anemometer

1
Thank you for purchasing the Hand-Held Anemometer.
- This product is designed to measure instantaneous wind speed.
Do not use it for other purposes.
- Please read this manual thoroughly before using the instrument
and keep the manual in a safe place for your future reference.
Overview
The wind speed is measured by 3-cup anemometer which drives the
AC generator inside. The rotation of the cups is transferred to the AC
generator which produces a voltage proportional to the wind speed.
Cautions
Do not drop or knock the instrument to avoid any deformation or
malfunctions.
Hold the indicator to level to your eyes for correct readings.
Do not use the instrument out of its measuring range.
The instrument can be used in rain, but do not tilt it more than 45º.
Be careful not to bend or pull the cable to avoid short circuit.
Do not use or store the instrument near extreme heat.
Never disassemble or alter the instrument.
Make sure to grab the bulged area under the cups when
dismounting the anemometer.
