JimStim problem at low rpm

Post by steftn »

Hi,

I have a problem with my NEW JimStim V1.5. Firmware is V2.0.3.
If i increase the rpm with the RPM-FINE pot very slowly at the beginning, the LED starts to flash very fast!
After that it seems ok, look:

Anyone know what the problem is?
I soldered everything twice, but I had the same problem again...

bye

The lowest possible RPM is 60. What you're doing there is that you are putting the fine pot in a position that is just between 59 and 60 so the JimStim starts and stops as fast as it can read the pot value. I'm tempted to say: simply don't do that, it's not needed for testing your MS.
