BME 680 static IAQ very high (bigger 1000)

[Isarvation]

Hello,

we have a sensor active (logistics office desk) since a week. Suddenly the static IAQ went crazy high. As far as we know, this IAQ is defined somewhat to 500. Can you elaborate how this can be and how we shall interpret this behavior.

See data here (we can supply the data as table, if necessary):

Only the the standard 'IAQ' output is restricted to the [0-500] range, but the 'sIAQ' output can breach above 500IAQ. Hopefully the data in this other post should provide more information.
