Calculation of mechanical errors:
Systematic Phase Error
The systematic error comes in because of the delay-time between the threshold point and the time when
the output is switching. It can be calculated as follows:
ϕ
∆ϕ ∆ϕ
ϕ ... systematic phase error in °
n ... speed of the camshaft-wheel in min
t
d
... delay time (see specification) in sec
