Hi again.

[quote user=""]Having to simply multiply the current averages by a scaling factor (here, 3) to get the correct measurement would already be helpful.[/quote]

I don't think it would be that simple.

We are currently investigating this issue, but we don't have a fix as of now.

Some reports of steps that fixes the issue (not for everyone):

- Updating the chipset drivers.

- Connecting through a USB hub.

- Using a USB 3.1 gen1 USB port

I've got the same issues, 3x too slow.
Hence I would also appreciate how to go on with this.

Thanks, Chris.

Hi Adrien!

Just wanted to let you know that I have forwarded your request internally to our dev. team.

Will get back to you when I receive feedback from them.

Additional info : the 3x scaling is with the PPK2 plugged in a front USB port in my computer, which I guess is linked to an internal hub. Plugging the PPK2 directly on a motherboard USB makes it worse, giving readings about 6x slower than real-time...
