On my DSO4104B if I try to use the Auto scale button with two channels turned on the osciliscope locks up and I need to restart it with the power button.
It does try to scale, and switches between channels altering the ranges before freezing. I tried Channels 1 and 2, and also tried 1 and 3. Both combinations lockup.
How can I use Autoscale on two channels at once?
Right now I am doing it manually and saving presets.
Actually, apparently now its working fine. Not sure whats changed but I can't get it to lockup again. Is now auto scaling two channels perfectly every time I've played with lots of settings since I started learning the scope maybe I changed something and that fixed the issue or it was just because it hadn't been used much? Either way, very happy with it now.
