I am using a USB-2416 and a USB-2416-4AO connected to signal conditioners to read a set of analog inputs. All the channels are plugged in, but when I send a signal to either CH7L or CH8L it pulls the other channels' signals up with it. This doesn't happen on any other channels, but since it happens on the same inputs on both boards, want to check if this is a known issue and if there is a fix, like reinforcing the ground signal, that could resolve it.

I'm trying to find the fastest way to read TC inputs on a USB-1616HS-4. When I use ul.t_in_scan() I can read 8 TC values with good accuracy. But when I use ul.daq_in_scan() with the CJCs and the 8 TCs, all the temperature values are off by 10-20 degrees (F), however they are still responsive to temperature changes and the direction of the differential signal is correct. Is there a way to find out the CJC offset, or is there additional calibration that I'm missing?

I'm using a USB-1616HS-4 and coding in python to read thermocouple inputs. Is there a work-around for making ul.t_in_scan() run in the background continuously the way there is for ul.a_in_scan()?

I am using mcculw in python to read analog inputs from a USB-2416-4AO. I call a_in_scan along with initalizing my class variables in function1() and later I want to access the data array in a different function, function2() within the same class. I am not able to call ul.get_status() for the background scan in function2(), and get Error 1026: Board number already in use. Is there a work around to this so I don't have to do everything in the same function?
