ProChrono Digital Error Message
I have a prochrono digital that functioned correctly. However on selling it to another member it failed to perform and so I took it back.
I suspect that the problem maybe that I disconnected the battery before sending it. When I turn on the switch it has a brief think then the message rdy appears briefly followed by "0". When I put a shot over it the thread number appears (1-9) with the figure "0" after. The thread number diappears after 10 secs or thereabouts. So the machine detects the pellet but does not detect its speed. It has no memory of the numerous shots put over it before posting. I feel that it may need resetting?
Does anybody have any ideas?
