I apologize if this post is in the wrong place, or has been asked before. I did search the blog without any luck.
I acquired a Fluke 8840A (according to the eBay seller) which works perfectly but is missing its display window.
How can I find out if it is an 8840A or actually an 8842A? From what I can see they look identical except for the logo on the display window?
I do hope someone can help me as I'm trying to acquire a display window for this amazing meter.
