Quick Start Guides to Equipment Operation

The water quality testing instruments should be well grounded (the voltage between PE and N is less than 10VAC, and the voltage between L and PE shall be 220±22VAC), and connected with the equal potential of the digital acquisition instrument (the voltage between the digital acquisition instrument and the instrument housing should be about OV). Otherwise, it may lead to electrification of the instrument housing, abnormal operation and abnormal data transmission.
