 Hi all,

 While auto calibrating the SR620 I get the message cal error  
 23 - the manual isn't that specific about this message, it
 only states, that error numbers 19 to 23 are caused by Stop
 TAC problems. 

The manual also states that error codes 19-23 are the
same as the start values (n - 16), so 23 minus 16 should
be the same as '7' i.e. 'stop linearity byte out of range'

 However, the counter counts, but I can't do automatic
 calibration any more.

 Anyone having experience with that?

Sorry, no further experience with that

HTH,
Herbert

 Thanks a lot
 Volker

Where do you read that, I can't find it :-/

Herbert, you are the best :-) I didn't expect the error codes in the 
programming commands section.


I'm afraid it could be a hardware failure.

Thanks Volker

Re: [time-nuts] SR620: cal error 23

2013-03-18 Thread Volker Esper


Running Auto Cal a few seconds after switching the counter on, the 
calibration succeeds, though with values different from the warm ones 
(who'd have thunk). After warming up, error 23 wins. I have to open it 
and do the old school trouble shooting with coolant spray...


However, any advice, tip, hint would be appreciated.

Thank you

Volker
