UMC202HD and Jitter

[Gio Bell]

Hello everyone. I'd like to ask a question about jitter. I connect the control unit of my Roland electronic drums to the computer with Behringer UMC202HD USB interface. The latency value is approximately 4 ms and is OK but the Jitter input and Jitter output values fluctuate continuously. They almost always remain on the green but sometimes, for a moment, they exceed 0.50 ms and turn yellow. I haven't figured out if this can only affect sound quality or even latency. In addition, I would like to know how I can make the Jitter stable and keep it constantly on the green. Thanks.
