I thought the 7063 would be able to show the min and max value alternatingly...
Seems that you have to set the function for the prog key with:
Menu -> Prog -> Modify -> MaxMin -> Max|Min|Input|PP
Then you can get the value for the selected function by pressing the Prog key.
Either the Min or the Max value, for switching between them you have to change the function in the menu.
So, thats not practically usable but no problem...
What the Input and PP setting is for ? No idea
