- Page 2 INSTRUCTION MANUAL QI-POWER-485-300-LV Using a serial link RS485-USB you can connect the QI-POWER-485-300-LV with the interface program FACILE QI-POWER-485. Using this software, allows you to set the Modbus address, baudrate, delay, the TV and TA ratio, to modify a filter in order to have fastest responce time instead of a more stable measurement (filter range from 1-speed to 5-accuracy) and to measure frequency on current channel instead of voltage channel...
