Hi there, I have a band new GHL magnetic stirrer but I just can't seem to get it to work. It's the model 2 stirrer and I have it connected to a doser 2.1 SA. The firmware 1.35. I can't decide if it's broken or I'm just being an idiot. I think I understand how to programme it but nothing happens, I can't even get it to stir using the manual override. I need a little help please.
