Re: TM-500 Test Module Question


I was looking at page 11 (front PCB schematic) and you're right meter LO isn't grounded

I got misled by the T1 and T2 annotations which I now realise are just are just "test points" to which you are connecting the BNC

Did you download the files from this file section (I have edited the folder name to remove the . at the end)?

The Google drive has now been updated anyway so the files are the same between the two.

I don't see where the meter LO is connected to ground in document version 1.7? Can you show me where you see that?
