[time-nuts] HP 5071A operating parameter trends

[Stan]

I have been running my "new" 5071A for the past couple of days. I've been
watching the output of the status message and captured a few of them below.
The first capture was immediately after the 5071A locked after coming out of
standby. 

 

Has anyone else been doing this? Are there particular trends I should be
aware of that might indicate the beginnings a problem? So far, my 5071A is
operating perfectly, with no errors on the log file.

 

Thanks,

Stan
