For those interested, I have uploaded the service manual for the Fluke PM-6681/Pendulum CNT-81 to the k04bb website. Too bad you can't calibrate these beasts yourself, special software is needed. Regards, Stijn Nestra

Hi, Thanks for uploading the Fluke PM-6681/Pendulum CNT-81 service manual to http://www.ko4bb.com/cgi-bin/search.pl Looks like calibration is relatively simple and no special software is required unless the instrument has lost its calibration information. If this occurs then an interpolation calibration is necessary which involves a "interpolator calibration program" which was included with the service manual on a 3 1/2" disk. The interpolator only needs calibration if the counter has lost its calibration information. It would be nice to find a copy of this program. Any suggestions from the group?
