Fluke 7220A 1.3 GHz Frequency Counter Powers On Untested
Picked this up at a local estate sale and really know nothing about it. Here is what I can tell you. I am unable to test it for its intended use but I can tell you have powers on fine. It will need a detailed cleaning as it is rather dusty. There is a power cord included however it is not the original one for it but seems to function perfectly. There is one small knob that seems to have some damage however in researching this I did not see this piece on other models? At any rate I tried to highlighted in the last picture so please examine it closely. No leads or anything of that nature included with the exception of the power cord. Really don't know what else I can tell you but questions are welcome.
