Is the code understandable? Did you experience similar problems?

import time, sched from ctypes import * s = sched.scheduler(time.time, time.sleep) handlePointer=c_short() vv1=c_long() vv3=c_long() vv4=c_long() mydll=cdll.LoadLibrary('/opt/picoscope/lib/libusbpt104.so.2') status_unit=mydll.UsbPt104OpenUnit(byref(handlePointer),b'EU341/118') if (status_unit==0): ...

I still have the same problem with the mV mode. But the voltage mode works without problems. So: mydll.UsbPt104SetChannel(handlePointer,1,5,2) does not work properly, while mydll.UsbPt104SetChannel(handlePointer,1,6,2) works. What's the difference between libusbpt104.so and libusbpt104.so.2, by the ...

750 ms delay did not change anything, unfortunately.

It is pretty difficult to connect the device with the internet now, so I haven't performed the driver update yet. What's the date of the driver, what is its name?
Because I installed the system only about 2 months ago.

Thank you for your reply. I use the screw terminal adapters, so pin 4 (the outermost) is connected to ground, and the differential voltage is between pins 2 and 3 (with 4 being positive). Here's a picture: pt104.png Multimeter Readings between 3 and 2 show the correct voltage. Plugging the screw ter...

Hello, I am having some weird problems with the PT-104, which reminded me a bit of this older post https://www.picotech.com/support/topic23701.html As a setup, I have only tried it in USB mode so far, and I use it for reading 3 different devices with mV and V output differentially, with the mV devic...
