Quick Start Guides to Equipment Operation

Installation of equipment

• 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.

• The power supply voltage range of the instrument is 220 ± 22VAC. When the voltage is unstable, it is recommended to install UPS or AC voltage regulator. Unstable input voltage is easy to burn out the power filter, resulting in abnormal power on of the instrument.

• Three pipelines (water inlet pipe, water outlet pipe and overflow pipe) shall be installed for the pretreatment of the instrument. See the installation requirements in the user manual for details. Excessive water pressure may cause damage or leakage of water sample valve, which may lead to equipment failure.
