You can definitely tell this thing it has never been used... No, I have not tested it, but being analog, i can't see why it wouldn't work or function properly... Just let me know if you have a problem with this function.But please do not request a return for user error... I do not accept returns on electronics, but if I haven't tested it and it doesn't work, then it would come back on me... Long story short?Just reach out if you have any problems or are unhappy with your purchase before you leave negative feedback... There are no instructions.That's why i'm considering this to be new/other

Pretty neat Being as old as it is. obviously, you can buy digital ones for cheap nowadays, and it kind of defeats the point of owning one like this....But if you're into vintage tools and tech and or teaching someone how to use one of these it could be a good tool to own...see pics for details. Please ask questions and request pics before you buy if needed. Shipping is based on location
