Under certain conditions the reload does not drop the load to 0 even when 0mA is selected, not until it is either restarted or the source delivers a bit of extra current. This is a problem for weak sources that can't provide any substantial start-current. I have had issues with this while testing a weak solar panel (4W panel on a cloudy day) and a usb "power pack".
Synthetic repro:
Connect a 7v 10mA source
Power up the reload
See that it reads 7v 0mA
Select 20mA
See that the source is overloaded, reading 0v
Select 0mA
The weak loads won't recover, and an ampere meter in series still reads ~10mA.
Restart the reload, the load recovers.
The expected behavior would be that the 0mA setting behaves the same as when the reload is restarted. Note that the solar panel test case seemed to require quite a bit more than 10mA to recover at the 0mA setting.
I use firmware 1.11 and I tried re-calibrating it twice.
