Yes, the battery on the PM6681 is a real problem, unless you have the unobtainable calibration program. The program uses the GPIB to perform the calibration: I have tried to figure out the GPIB commands involved in the calibration process by looking at the firmware dump... the commands are clear text. I wasn't able to find anything.
