Different readings of RPM, in MT / DMM

Post by eMTea »

I have a Digital multimeter with RPM measuring.
MT shows 6000RPMs

MT set to half speed:
DMM shows 1150RPMs in 4stroke and 2stroke shows 5750RPM's

MT set to normal:
DMM shows 3000RPMs in 4stroke and 2stroke shows 1150RPMs


Any other of you who had issues with this?
