Keystroke the “Esc” key The Main Menu should appear. Be extremely careful at this point. This is keystroke driven and mistakes could occur.
Keystroke Y (no echo in my case) This would be the air temperature of inside the box. Do the best you can, but not critical. Try to stay within +- .5C if possible. Humidity +- 2% is also acceptable.
Place “Zero-Air Chamber” on Axis Using rubber / elastic bands to secure box works quite well.
Choose Axis W is chosen with this demonstration
1 Axis Calibration Complete Perform this task with all 3 axis’ . “Enter Key” returns to Menu.
Data flow This demonstrates an acceptable W axis with the box still attached with calculated temperature.
Thank-you for your dilligence and hard work! It may be noticable after a few days the calculated temperature may drift. This is not of great concern since that is not a reflection of wind turbulent measurements.
