Starter current signature RPM
Hi Pico group.
I am looking for help on how to apply math channel to accurately display RPM for starter current signature wave form during relative compression test.
Thanks for any advice.

Re: Starter current signature RPM
Why not just place your two vertical cursors at 720 reference points, let the software display rpm, then multiply by 2 to get the approximate rpm?
It would make more sense to capture the CKP and build a Maths Channel off of that CKP wave.

Re: Starter current signature RPM
Thanks Grant.
Was just trying to get it to work as in 'Math is Cool 1' using current signature and 60/3×Freq math as laid out in the example.
