Hi, I searched the entire internet and this forum, of course, as well. I've got the mentioned densitometer but no manual and would like to ask if someone kindly has a source or a copy of it? The use of the densitometer in common is straight forward but there are probably also some "hidden" features I'd like to know: - Can this device somehow be calibrated? - What is the meaning of blinking measures? - What do I need the send button for? - Can there any button combination be used for device configuration? Would be nice if this forum expertise might have any insides THANKS!
