The ZHL4921G supports networking functions and supports one-to-one and multiple-to-one networks. This need is very practical for some specialization scenarios.
Analog auto-calibration threshold reporting.
The ZHL4921G presets the analog linear calibration parameter value, the user only needs to modify the k/b value to achieve the linear calibration effect. In addition, the effect of analyzing the analog data can be realized by adjusting the k/b value, and the threshold will be reported.
