[time-nuts] FW: HP-5732A operation with no CRT display.

[Steve - Home]

Lester,

Might that be a 5372A? 😉

I have it’s brother, the 5371A. I turn it on every few months to make sure it’s still working. I’m going to be away for at least a week but will look for my documentation when I return. My 5371A is on the disposal list as I start my downsizing.
