At first thought there was a problem.
In the setup window:
If you go from autorange to manual range in DC, AC Voltage such as DC, AC current, you will not get back to autorange (radio button remains with manual).
But it works when you are in this setup and at the same time (via mode popup) in the same measurement mode of the setup.
So no mistake, all well.
A luxury problem:
Would it be possible to choose not only beeper on / off but also the three volume levels in diode and continuity ?
Otherwise I could not find anything so far that would not work.
