Hello,
?
I have a very nice 3457A which has a 40-year old battery. New batteries are quite inexpensive and easy to find, but I'm quite scared at the prospect of replacing the battery without first dumping the calibration data to a file, and having a way of reloading it if anything goes wrong during the replacement process. Someone already tackled the problem of storing the cal data on a PC () but I couldn't find anything about how to restore the data from the PC to the 3457A if the data is lost.
Right now my 3457A is sitting there with a battery which is 40 years old, and counting ...
Any help or pointer(s) would be sincerely appreciated !
?
Joel
