Overload protection on 526?
Posted: 03 Dec 2011 19:31
Am I really the first user to post here?
I am using, carefully and with trpidation, my 526 for automotive diagnostics. All my colleagues tell me to get a picoscope automotive USB scope that has internal fusing and overload protection, plus inputs that will view 100 volts with no attenuation. I like my 526, and have had it from new, so for that reason, plus to confound them, I persevere. I have two questions though. If I was careless with it and it saw a few hundred flyback volts from injectors, or I had grounding issues, what's the worst that could happen? Could it be rendered scrap, would it be only factory return repairable (where is the factory, do you make these in the UK), or could I take the lid off and do "something" myself?
Is there any external protection I could easily add?
The Picoscope automotive scopes, and their dedicated automotive software, allows for timebases of up to 1000 sec / division, allowing over 2.5 hours of slow updating monitoring. I bought your 520 RM roll mode licence the other month, but have had little time to play with it, does this allow me to do something similar?
Finally, do you do any USB signal generators? If so, do any have separate power supplies than from the USB port, to up their voltage at load outputs?
Thank you.
