Hi,
I'm working with a new T7-Pro. I have encountered a strange thing... Using Kipling and the LJLogM i can set the streaming at 100khz with a range of -0.01/+0.01 and an index resolution of 1. But, then I try to do the same with python code... the problem arises using the function _staticLib.LJM_eWriteNames , this function just not let me put 0.01 on the range value.
I have seen in the table A1.4 that with this parameters (100kHz and -0.01/+0.01) is just N.S. (not supported), but, then, how I can make the measurement with the Kipling and LJ`StreamM? I analyzed the data and it seems ok, the labjack can support it, but if I try to enter the parameters "manually" (by script) the device don't let me.
There is a way to make the measurement (Streaming at 100kHz with a range of -0.01/+0.01) using the script?
Thank you.

Are you getting LabJack Error #2621: STREAM_SETTLING_INVALID when you call LJM_eStreamStart?
I agree that with a single-channel stream you don't need any extra settling time as the mux is not changing, so you should be able to do max speed at any range. We are looking at why firmware does not let you do 100k with the 0.01 range, but for now you can make it work by writing STREAM_SETTLING_US = 5 before you start streaming.
I'm not sure what you are saying about LJLogM. It does not use stream mode and generally does not go over 1000 iterations/second. Perhaps you are talking about LJStreamM, but it gives me the same errorcode 2621 if I first use Kipling to set the range of my channel to 0.01.
Hi again,
First, thank you for your fast response.
Yes, I am sorry, I mean LJStreamM.
Thank you for the tip. It work perfectly, now I can stream at any range at max. speed. And you are right, with kipling and LJStreamM normally I obtain that error. But I downloaded a new version and sometimes worked... I was not understanding why.. I remember that if with Kipling I set, first, the range at 10, then with LJStreamM make a stream, close the LJStreamM, open again Kipling and setting the range at 0.01, this time LJStreamM let me Stream at any speed.
Anyway, thank you for the tip.
