**General Mach Discussion / RPM not under 38**

« **on:**August 22, 2010, 02:44:11 PM »

Situation: disk with one reflecting part and an opto sensor.

It gives a nice stable RPM DRO.

But when I let the machine rotate under 38 RPM, the S-true DRO shows wrong numbers in a random way (like 1546 rpm).

Does someone know how to solve this problem and make it possible to measure under 38 rpm?
