It could be a grounding issue. The touch-screen may work better if the instrument is properly grounded ( PE via the mains cable).
That could very well be the case, however the issue is that in Lebanon we do not install a ground connection for in residences so how can I properly ground the instrument to assure the touchscreen would work properly?
Could I create an artificial ground somehow?
You could use any metal plumbing in your house, but this may be illegal and could be dangerous when the dmm6500
develops a short circuit between mains and ground, at least wire in a 30mA rcd.
Better is using a separate grounding rod if soil conditions allow (wet and soft is ideal, dry and hard is not).
Dear drummerdimitri, try connect your hand via anti-static wrist straps to DMM chassis. Before that check resistance of the cord, it must be 1M or large.
If major cause is grounding, you should see changes.....
All my equipment, rack's, table mat and all power source has been grounded, i can't check DMM without ground.
All our plumbing is plastic, does that mean the only option is to stick a grounding rod in soil? How exactly will the power connections look like? Please explain
The power cord supplied with the DMM6500 contains a separate protective earth (safety ground) wire for use with grounded outlets. When proper connections are made, the
instrument chassis is connected to power-line ground through the ground wire in the power cord. In the event of a failure, not using a properly grounded protective earth and grounded outlet may result in personal injury or death due to electric shock.

How can I tell if the touchscreen is the culprit or a bad firmware?
Easy, when you have a buttons that do not respond anymore, go to the webinterface an try to click it with your mouse.
If it works you know it's the touchscreen.
(keep in mind that dragging with the mouse doesn't work very well, so you cannot test that)
And also if you pressed "copy to power up" in run scripts with a bad script it could put it in a bad situation every time you reboot. (not sure if that is erased with a reset or if you have to overwrite it)
Attached the default "empty script" you can load. (remove .txt)
How to remove the .txt extension? I cannot just rename it in windows 10

In GPIB this should be simple, but I would like to try to do something with a Raspberry Pi "tablet" I had shelved away. I bought an RJ45 cable and got the DMM6500 web front panel up on the RPi display. The RPi has Python installed.
You can't use LXI(RJ45 Jack) with RPi's and Python. PyVISA library require a NI-VISA software. But NI-VISA do not support RPi's
Try use my code of LXIIDL software(link below) as example written on "C" language or see code of lxitools.

Yes, that python-vxi11. When I tested with 6221 or B2987A I did not use E5810A, but direct RJ45 connection to these instruments.

Thank you very much. This will be my first goal.

So it turned out that I received this calibration document. I believe that this is useful and interesting for everyone. I do not have much experience using this device. But something seems to be true, and repeated very well.
Brad, maybe this is not a very stupid recommendation - to make cursors with different colors.
Thanks.
