I own a LAB1, purchased in October 2010, so out of warranty. The dial knob of the multimeter section is not working correct. The 4 dial settings for the Ampere readings do not function, unless I keep on pushing the knob into the housing at the selected setting, which of course is not doable because I need my hands to do a measurement. All other settings work fine. I already took the multimeter section PCB and knob apart (ball bearing type of dial), cleaned the contacts and reassmebled everything, but no change.
Does anybody have a tip or suggestion? Are there spare parts for the multimeter section available?
