content: Thanks picburner,I don't mind paying 55$ for the service and calibration manual.The question is: Where to get it?I asked Fluke and they claim it is not available anymore.Although this instrument is still offered for sale - at least in Germany.In regards to the ebay item, I made my own transfer standards for R, L, C.I had the values verified by a calibration lab and they work extremely well.All I need is the calibration procedure for the PM6306

content: Quote from: Jacek_Paw on January 13, 2017, 08:13:46 amSorry to say, but after a lot of effort and even some money out the door, I was not able to obtain a Service Manual copy for the PM6306However, I was able to get a Service Manual for the PM6304 and that one is very similar to the PM6306. The only difference is really the front panel interface.Send me a PM with your email address, so I can forward you the Service Manual for the PM6304These are amazing meters and I have bought a few more of them, repaired and restored them and they look like new now.I have even painted one completely new.Compare my first picture above.One of them even has all option, including RS232, DC, GPIB

content: Have you checked the calibration of your PM6306.I ended up having one of my PM6306 calibrated in an official cal laband all checked values were right on spot and no calibration was needed.So far I have not been able to locate the service manual for the PM6306.

content: Quote from: HighVoltage on August 13, 2017, 03:36:16 pmHave you asked the "official cal lab" for the service manual?How did they managed to do the calibration without the service manual?User's manual usually have "performance check" but rarely the calibration procedure.

content: I have a PM6306 with software version 1.2My meter doesn't finish the zero trim on 100/120 Hz.It seems like a software error. Does anyone here have that same problem?Can someone read the ROM in the PM6306 for me so I can try a new (or older) version of the firmware?Hope you can help!

content: If the zero trim fails, it is usually a cable connection.What cable are you using?If you are using an original cable with LEMO connector, make a short without the original cable and use some 2 mm banana plug cables instead.If this work, you know the problem is in your cable or the LEMO connector in the instrument.I don't believe it is a software problem.

content: Quote from: banditbiker on September 05, 2017, 09:27:43 amYes, I had exactly the same problem before on one of my PM6306.In my case it was a bad solder connection on the LEMO connector inside the instrument.The higher frequencies had no problem.

content: I checked the connections internally, there doesn't seem to be any bad solder joints on the lemo. I resoldered everything. Still the same.The behaviour I am getting is that the unit sees a short when there is none.When executing zero trim, the unit first tests short while there is none.It only does it with 100, 120 and 200 Hz. The rest is fine (even 50 and 60, 300, 400, etc.)Unfortunately the 6304 and 6306 are quite different inside... So I can't use my 6304 manual.Does anyone have a 6306 manual maybe?P.S. I really do appreciate all the help! Thanks!
