?MEASUREMENT PARAMETERS?Multi-function meter can measure DC voltage, current, active power, frequency and energy consumption. The voltage measurement range is 0.05-300V (When the test voltage is ?7V, please use the independent power supply mode)?The current measuring range: 0.02-300A (Can be matched with 50A, 100A, 200A, 300A four kinds of shunt)?The power measurement range is 0.2-90kW?The energy consumption measuring range is 0-9999kWh.
?ALARM INDICATION?Alarm indication: over power alarm: active power threshold can be set, when the measured active power exceeds the threshold, an alarm can be issued. The overload alarm function not only protects the instrument from being burnt out, but also serves as a safety protection against fire.
?APPLICATION LAYER PROTOCOL?The application layer use the Modbus-RTU protocol to communicate.At present, it only supports function codes such as 0x03 (Read Holding Register), 0x04 (Read Input Register), 0x06 (Write Single Register), 0x41 (Calibration), 0x42 (Reset energy).etc.
?NOTE?RS485 interface is passive output, need external connect 5V power supply and the external power supply should ?100mA.When the input test voltage is less than 7V, it must supply 5V independent work voltage through USB port. Do NOT use the USB port bring by your PC to be the independent power supply, otherwise it may damage your PC.,if you have any problem about the product,please feel free to contaut us,we will reply you in 24 hours.
