I am trying to set this Nano with amplified jig up consistently. I have latest firmware on 2.8" H model. Sometimes the NanoSaver app cooperates and i can measure, sometimes it doesnt, like right now. I am measuring 10.7mhz filter. I set markers to 10.2, 10.7, 10.9 and they always change. I usually get cutoff error when analyzing. Overriding marker values seems to correct that error and I can measure fine. When I reset it all and set back up, i keep encountering these issues. What am I doing wrong?
