User and Maintenance Instructions Instruction Manual

Before installation, cut off all power supplies. Align the front interface of the module and insert it smoothly into the terminal board, then tighten the fixing screws. Complete the two-wire connection according to the terminal markings, and reliably ground the shielding terminal. Use extension cables or plugs to achieve row-column expansion, ensuring a firm connection. Configure the matrix mode and trigger parameters in the software, and then data can be collected.

Maintenance Instructions

Place the equipment in a dry and ventilated area, maintaining the rated temperature and humidity. Keep away from strong electromagnetic sources, dust and corrosive gases. Regularly check for loose screws, oxidized terminals, and damaged cables. Address issues promptly. Cleaning requires power disconnection. Wipe the surface and terminals with isopropyl alcohol, then power on after drying. When left idle for a long time, remove it and store it in an anti-static bag in a cool and dry place.
