2. Selection among max wind speed/min wind speed/average wind speed/current wind speed.
3. Temperature unit selection between ℃ !
4.Inlet area set
5. Selection speed unit among M/S,KM/H,FT/MIN, KNOTS and MPH
6. Reading hold
7. LCD backlight
8. Manual/automatic turning off
9. Beaufort scale
10. Wind chill alert
11. Retractable drag rod
12. Low battery indication
