Hi,
Apologies for the very basic and rather odd question. I just received the Amprobe TMD-56 and while it works fine the package wasn't sealed and was really dusty. Seems like it has been in storage for a years . The sticker on the back was dated 2021 but on peeling it off I found that it was covering another sticker that said manufactured in July 2015. Is this something I should be concerned about or does it not matter for a device like this? Should I be getting a replacement is my question?
