RS485 online software download: https://www.mediafire.com/folder/fplvic7ztnvbo/at2pl Without leakage protection function, supports RS485 communication With leakage protection function, supports RS485 communication 1.33 # TFT HD Color Display Guide rail type smart meters (Display Panel:1.33 inches TFT-LCD HD Display Panel Graphic 240X240 RGB Dot-matrix) New product Mode 1: AT2P voltmeter with leakage protection function At present, our label stickers retain the RS485 wiring port, and we need to purchase the RS485 option to achieve its functionality! Model 2: AT2P without leakage protection Please upgrade to V1.10 via smart life app Can display the latest interface display! Includes 100A relay with 4 types of protection Under voltage protection, over voltage protection, over power protection, over current protection Firmware upgrade, WiFi networking We will release new firmware from time to time, WIFI remote upgrade, please click on the upper right corner of the APP to view >> device upgrade >> update, you can upgrade the firmware Explanation on wiring methods, magnetic retention relays, and automatic recovery of undervoltage and overvoltage When this meter is first powered on, the built-in magnetic retention relay needs to be reset. During this period, it will be turned on for more than ten seconds and maintain the output (delay protection). Only when the startup is completed and the measurement interface is reached, can the over limit enable (such as overvoltage, undervoltage, overcurrent, and overpower protection functions take effect) and the normal working mode of the measurement data be achieved, This meter can freely set the recovery time for undervoltage and overvoltage (1-99 minutes). When the voltage is restored, normal power supply will be restored within the time you set! If you have any objections, please purchase with caution! (In view of this, please strictly follow the wiring diagram in this table to connect the air switch at the output end, and wait for the meter to start before turning on your device's air switch.)
