After the composite gas detector is used for a certain period of time, due to the on-site environment and the life of the instrument itself, the detection is unstable and inaccurate. Therefore, it is necessary to restore the factory settings of the composite gas detector, so as to better ensure that the instrument can complete normal and efficient work. Do you know how to restore the factory settings of composite gas detector ? The following is an introduction by Yiyuntian:
