Portable analyzer for metering wiring

The invention discloses a portable analyzer for metering wiring. The portable analyzer comprises a host, a single-chip microcomputer arranged in the host, a power supply module, a signal sampling module, a signal conditioning module and a parameter display module, the signal sampling module collects alternating current, transmits the alternating current to the signal conditioning module, and transmits the alternating current to the single-chip microcomputer after voltage stabilization and conditioning of the signal conditioning module. The parameter display module is electrically connected with the single-chip microcomputer. The power supply module supplies power to the single-chip microcomputer, the signal conditioning module and the parameter display module. The metering wiring portable analyzer based on the MSP430F149 single-chip microcomputer is simple in structure, low in cost and low in power consumption, can measure and display alternating current parameters, and is convenient for personnel to carry on
