If I test Ch B with a 9 volt battery (Setting: DC, 10 v) the trace jumps up and stays there. If I use the same probe plugged into Ch A (Setting: DC, 10 v) the trace jumps up and then quickly decays back to zero. Am I missing something? Is there some other setting I need for Ch A to properly register DC voltage? Does it sound like a hardware problem? (2.6, 1.41, 2.45b)?
Ant suggestions would be greatly appreciated.
