I was looking at my old 501 problem and noticed the right arm ECG lead to connect your post was broken off. I ordered a new one but want to find some instruction before I open up this piece of equipment. Does anyone have any advice on where to start replacing it? I also need to replace the AC socket on the face of the unit.

Also, my unit needs to be calibrated but I do not have the software to do it. Does anyone here have calibration instructions and access to the required calibration software?

Thank you so much in advance!

While our regular safety analyzer is in for calibration I have had to attempt to use the 501 Pro for ESI tests. Unfortunately, I cannot get it to do what I want it to do and I have no manual and can't find one. 

Specifically, when I try to test for grounding resistance, the readout flashes "299.9" on and off. Like I said, no manual, so I don't know what this is telling me or how to get that specific test to work.

Any ideas anyone? Thanks.
