content: The Fluke 105B I have repaired once had trouble with the memory. It behaved irraticly with no calibration, weird characters onscreen, missing channels, keys not working etc. There where settings in the menu to reset all kind of memory settings, programs and whatever. After this and a reboot all have been working OK.
