Stabilization period

The stabilization period is relevant for AQT530 devices that have the gas measurement.

When AQT530 is switched on, let the unit stabilize before using the measurement results. The stabilization time depends on usage conditions, but typically 3 - 5 days in enough to ensure optimal performance.

The units take measurements during the stabilization period, but the measurements from the first 24 hours after power-up are marked as invalid.
