Jeff,

Too late. 

I have already moved the jumpers and adjusted all of the front panel 
adjustments to achieve the desired output voltages.

Since I don't have any 'historical' data about the performance of my specific 
unit, I will 'start from scratch' on the unit I now have.  Whether to send it 
out for calibration or just keep it, adjusted by the 3458A, and watch from now 
on is the issue.

I don't have enough data to decide about long term stability at this point but 
I am gaining valuable information about how long it will last on batteries and 
how to go about preparing it for shipment for calibration if I go that way.

Thanks for the input.

Joe

Hi,  



Are you guys adjusting your 732As? 

I have a friend that works in a large CAL lab and he told me to never adjust my 
732As, just compare them. 

They send out their 732 Bs to Fluke but are never adjusted, just compared and 
sent back with current voltage reading ?? 



Thanks - Jeff

It was recorded on the original factory cal certificate.  I have the original 
certificates for two of mine.  The others had rear panel stickers applied by 
their original owner (a cal lab). 

A properly working, good example should hold 0.1 ppm or better year in, year 
out.  I've seen some that do not meet that, but lots of them do.  I'm not aware 
of any other non-JJ standard that can match it, including most 732Bs.  (Some 
folks think 732As are generally better than 732Bs because they are older and, 
thus, more stable because better aged.  I think there is more to it -- many 
732Bs are plenty old enough to have settled down to that level if they are ever 
going to, but even the older 732Bs don't, in general, seem to exhibit quite the 
stability of the 732As.) 

Best regards, 

Charles
