output is not close to the expected frequency tolerance. The first of

vendor then sent a second unit which puts out a signal at 10,000,025
Hz.
Could it be the transport conditions that cause the problems? i have
noticed that all I get that comes by DHL/UPS/TMS is very cold on
arrival. Another possibility might be security screening. I stopped
getting film from the US because some got fogged, maybe by x-ray
security.
I doubt it. I have one I bought several years ago from a US source that
matches all the problem descriptions. I think it is something inherent
in this particular version of 5680A (with 5 V needed and no known
adjustment method).
