Hi , I've been given a digitek data logger meter, now the problem I've put usb software in with the adapter to the meter, but do you think I can find what port !!!, it flash up com4 at one point, but I have no idea of the setting I need bits and parity I think it's called, damn computers, so if anyone has a digitek DT-4000zc, which I think are made by others to, can you give me any advice, please. I think it has to be me as I can't get the UNI T 61 e to work either, old radio of TV yes no problems, computer jargon no a chance.
