7. Wind Speed& Temperature vs. Altitude& Baromtric display
Pressing the “SET” key to toggle between wind speed and altitude display
7.1 Wind Speed& Temperature Display Mode
7.1.1 Wind Speed Display
There are three wind speed display modes:
Current wind speed (WIND)
Maximum wind speed (ΔWIND)
Average wind speed ((ΦWIND)
Sub display: 1.display temperature/wind chill under
wind speed mode. 2. Display barometric and
temperature under Altitude mode.
Main display: Wind speed/Altitude display modes

Press the + key to toggle between the three wind speed display modes.
Current wind speed maximum wind speed average wind speed
Current wind speed: device will measure the current speed and update every 1.5 seconds.
Maximum wind speed: During the measuring, the Maximum value of wind speed logged. It will be cleared
after a restart.
Average wind speed: The average value of recent 10 times measurements of wind speed..
Wind speed measuring range
The wind speed measuring range is 1mph(0.3m/s) ~ 67mph(30m/s), if the speed between 0.0m/s
and 0.3m/s,the wind speed will show 0m/s,and if the speed over 30m/s,the wind speed will show
“--.-“.
Note:
1. It will stop measuring wind speed once exit wind speed mode.
2. If no wind speed or no button operation within 30 minutes under wind speed mode, it power off
automatically.
3. Current, maximum and average wind speed will be cleared after power off.
7.1.2 Temperature Display
There are two temperature display modes:
Temperature
Wind Chill
Press the Light key to toggle between the two temperature display modes.
Temperature Wind Chill
Current temperature:
The anemometer measures temperature in real time and updated every 1 minute. The Temperature
measuring(and wind chill) range is -30℃-60℃. If the temperature out of range, it display “- -.-”. and
the wind chill also display “--.-”.

Wind Chill
The anemometer calculates automatically wind chill, which can provide useful information for
preparing outdoor activities in cold weather. “Wind chill” provides an indication of how cold it feels
given the combined effects of the actual air temperature and the wind speed. Wind chill temperature
is only defined for temperatures at or below 50 °F(10 °C) and wind speeds above 4.8 kilometers per
hour. Wind chill temperature will be the same as current temperature above 50 °F(10 °C).
7.2 Altitude& Baromtric display
7.2.1 Altitude Display
There are three altitude display modes:
Relative Altitude
Maximum Altitude
Absolute Altitude
Press the + key to toggle among the three altitude display modes.
Relative Altitude Maximum Relative Altitude Absolute Altitude
Absolute Altitude
With the increasing of altitude, the barometric will be decreasing accordingly. The anemometer will
calculate the altitude of current position relative to the horizon, based on the changing of barometric
value.
Relative Altitude
The altitude at the spot when the anemometer is powered on will be set as “0”.
Note: The altitude (both ABS and REL Altitudes) will show” --.-”if the barometric is out of the range
600-1100hPa.
7.2.2 Barometric Display
Press the Light key to toggle between barometric and temperature display modes.
Barometric Temperature

Barometric
When user select the barometric display, the anemometer will measure and update the barometric
every 3 seconds in the first 3 minutes. After 3 minutes, the updating interval becomes 1 minute. And
the ABS/REL altitude will be calculated based on barometric values.
Note: The barometric will show” --.-” if the barometric is out of the range 600-1100hPa.
Note:If no button operation within 24 hours under altitude mode, it power off automatically.
8. SET Mode
Press and hold the “SET” key for 2 seconds to enter the setting mode.
(1) The wind speed unit will display and flash. Press “+” key to cycle among m/s, Km/h, mph, Knots
and ft/min. Press “SET” key to confirm and advance to the next step.
(2) The temperature unit will begin flashing. Press “+” key to cycle between °C and °F. Press “SET”
key to confirm and advance to the next step.
(3) The barometric unit will begin flashing. Press “+” key to cycle among hPa, inHg, mmHg. Press
“SET” key to confirm and advance to the next step.
(4) The altitude unit will begin flashing. Press “+” key to cycle between m, feet. Press “SET” key to
confirm and advance to the next step.
Set Wind speed unit Set temperature unit Set barometric unit
Set altitude unit
Long press the “SET” key to exit the Setting mode and enter to measuring mode. Press and hold the
“SET” key for 4 seconds can enter the Power Off status,
Note:If no key operation in 15s, the unit will return to the normal mode automatically.
9. Other features
9.1 Beaufort wind scale (bft)
The Beaufort scale is displayed in bar graph (0-12). This is a system for estimating wind force
without the use of instruments based on the visible effects of the wind on the physical environment.

9.2 Low battery display
The unit will detect the voltage of battery just after power on. In normal
mode, the unit detects low battery every 10 minute. In power off
mode do not detect it, if the battery voltage is low, the icon will
be displayed.
9.3 Power ON/OFF
Press and hold down the “SET” key for 4 seconds to switch the unit
ON or OFF. In power off mode the unit will sleep and do not detect
the wind speed and temperature data, all the history data will be
cleared too.
In Wind speed mode, the meter will automatically switch OFF when no key is pressed and the wind
speed is zero for 30 minutes to save battery life.
In Altitude display mode, the meter will automatically switch OFF when no key is pressed for 24hours
to save battery life.
10. Glossary of Terms
Term Definition
Accuracy Accuracy is defined as the ability of a measurement to match the
actual value of the quantity being measured.
Beaufort Scale The Beaufort Scale is an empirical measure for describing wind
speed based mainly on observed sea conditions (on land it is
categorized by the physical effects it has on vegetation and
structures). Its full name is the Beaufort Wind Force Scale.
>32.6

Comfort Level
Comfort level is the body’s effect based on ranges of temperature.
Range
Range is defined as the amount or extent a value can be measured.
Wind Chill
Wind chill is the felt air temperature on exposed skin due to wind. It
measures the effect of wind on air temperature. The wind chill
temperature is usually lower than the air temperature, since the air
temperature is usually lower than the human body temperature.

12. Troubleshooting Guide
Problem
Solution
Wind Chill shows --.-
The wind chill is meaningless above 50 °F, and is not
displayed (out of range, or - -.-).
Impeller appears imbalanced.
It is normal for the impeller to oscillate as it comes to a
stop, and it is not imbalanced. The unit contains a very
small magnet that responds to the earth’s magnetic
fields. This does not affect the accuracy of the wind
speed readings and only apparent when slowing or
accelerating.
Vane is noisy at high speed.
This is normal for the vane to vibrate at high speed.
Do not operate above 67 mph.
Above 67 mph, the unit will display ---.
Display is dim or disappears.
The LCD display will not operate below approximately
14 °F. Use the warmth of your body or environment for
use in cold weather conditions, or Battery is dead.
Replace the battery.
