We mainly talk about dominant drift, which can be seen intuitively. The dominant drift is zero drift up, the number is getting bigger, if you do not deal with it in time, it will produce false alarms. The error of the general gas concentration alarm is 5%, and the alarm point is generally about 20% of the full scale. We use flammable. Gas alarms as an example: If the drift number of flammable gas alarms is 5 or less, we can temporarily adjust or zero the host alarm directly. If it exceeds 5-10, we consider zeroing through the probe zero adjustment knob if it exceeds 10, professionals may need to check the zero and calibration.
