How to Calculate Staff Intercept?
Staff Intercept calculator uses Staff Intercept = Distance between Two Points*(tan(Vertical Angle to Upper Vane)-tan(Vertical Angle to Lower Vane)) to calculate the Staff Intercept, The Staff Intercept formula is defined as the difference in reading between top and bottom crosshairs. Here it is the distance between the two vanes. Staff Intercept is denoted by si symbol.
How to calculate Staff Intercept using this online calculator? To use this online calculator for Staff Intercept, enter Distance between Two Points (D), Vertical Angle to Upper Vane (θ1) & Vertical Angle to Lower Vane (θ2) and hit the calculate button. Here is how the Staff Intercept calculation can be explained with given input values -> 3.982713 = 35.5*(tan(0.4363323129985)-tan(0.34033920413883)).
