I have an oscilloscope picotech 2203 with the maximum input voltage of 20V. In your website it is mentioned, that overload protection is activated after reaching 100V. What happens in the range of 20-100V? Is there any chance to destroy the scope if I accidentally jump into signal of 70V with a probe 1:1 (lets say vehicle injector signal) ?
And, also, what happens if i jump into signal higher than 100V (i believe ignition coils have a few hundred volts of input voltage) ?
I of course must use the appropriate attenuator for measuring signals like this, but in case i mix the wires, is there any chance to destroy the scope this way, or does the overload protection fully takes care of situations like this ?
