My clients want to log a second RPM for a helicopter rotor. Â We are using a simple sensor that sends a 12v pulse with each rotation.
Since there is no RPM function in the DI menu, I'm thinking of using the Speed function and setting the calibration modifier to represent the proper RPM.
Is this a good way to solve this? Â If so, what is the right value to put in the modifier?
I have a sneaking suspicion that I'm wrong, however. Â Any ideas?
