Does anyone know what this yellow label is on the back of my 3457a? I know it's not the serial number label.
I'm trying to have Keysight in Australia calibrate the meter, and they are telling me they can't do it without the serial number (which I don't have). Awkward and inconvenient.
Unfortunately I bought the meter from an old guy who was closing his shop back in early 2010 while I was in the US, so I've got zero hope of tracing it back from him.
I'm hoping that tag is some form of traceable test they might be able to use to dig out the serial number, but it's a kinda vain last-resort sort of hope. I have noticed that a majority of units for sale on-line seem to have that tag, so I'm keeping my fingers crossed it's useful.
Anyone have any ideas?
