3.2 Fan Equations / Selection
Some Fans have 1, 2 or 3 calibration equations :
3 Equations : Enter all 3 equations and inequalities as shown above.
2 Equations : Enter 1 of the equations twice. Assume equations are : V=0.6564n+0.0094 n<0.14
V=0.6981n+0.0035 n>0.14
Enter them as : V=0.6564n+0.0094 n<0.14
V=0.6981n+0.0035 0.14<n<0.15
V=0.6981n+0.0035 n>0.15 (make this inequality bigger than the first)
1 Equation : Enter the same equation 3 times. The inequality doesn’t matter, so just set it to n<1.00 n>2.00
