So you are saying I shouldn't use 1/10x probes, iss that b/c of the switch? and the other reason is b/c the AD2 is low voltage, so when probing lets say a 50v DC voltage I would need a 10x probe to bring the voltage down to 5v? which is then safe for the AD2
I think the AD2 is pretty fragile compared to a normal scope (50V (probably peak to peak) vs 300V RMS and I would hate to lose mine due to a screw-up. OTOH, I don't work with voltages outside of +-15V and, more often than not, I'm only working with the internal +-5V supplies.
Probes only come into play when you use the BNC Adapter so, most of the time, when using fly-leads, you need to be very careful. I might just make it a practice that when not using the internal supplies, for whatever reason, use the BNC adapter and 10x probes. Always! That isn't much of a constraint considering you are using probes anyway. Just use the right ones!
I bought a pair of the 3904-2 probes specifically for the AD2
https://probemaster.com/3900-series-scope-probes-100-mhz/It all comes down to what you expect to do. You could take a pair of 1x/10x probes and disable the switch (a wee bit of epoxy?) to prevent them from being set to 1x.
Protect that AD2! You might also need to pay attention to the digital leads if you run into some awkward voltage level. It seems unlikely but maybe it could be a problem.
If you don't know what voltage to expect, use a DMM first.
I really like the AD2 but it's expensive, I don't want to mess it up!
