Installed a zen and 5 days later channel A is reading in the 2500s. I assume there’s a bug in there. I also assume A is closer to the USB and the long thin slot is the one I want to aim for with the vacuum but I wanted to confirm.
I can’t find instructions re cleaning out the zen. Just the II.
Hi @Eric, the process for cleaning the laser counters in the same for every device. The “B” channel is the laser counter closest to the USB port. We will update our documentation to reflect this.
