I'm kind of interested in the "read" part, too. The 3468 is a headache to calibrate without specific equipment, so having a backup would be nice.

Simply reading the CAL factors won't clear the checksum error. Writing them should calculate new checksums and then clear the error, but this doesn't calibrate the instrument, it just clears the error.
