[time-nuts] SR620 TCXO calibration

[David C. Partridge]

I think I'm being dense, but I can't work out how to get this thing to
display CalDat 04.   I have managed to get it to display CalDat 0 value, but
can't work out how to step through to view adjust CalDat 04.

Once I do  get there, how do I manage to adjust the CalDat value while
observing the output of measuring my GPSDO 10MHz output at the same time?

Please could someone put me out of my misery?

Thanks
Dave
