The invention discloses an embedded check meter for an electronic mutual inductor. The check meter comprises a high-speed DSP (digital signal processing) module and a precision resistance voltage dividing module, wherein, an input terminal of the high-speed DSP module is respectively connected with a CPLD (complex programmable logic device) module, an optical Ethernet chip and a power Ethernet chip; and the precision resistance voltage dividing module is connected with an input terminal of the high-speed DSP module through a range switching module, an analogue switch module, a PGA (programmable gain amplifier) module and a high-precision AD (analog-to-digital) module in sequence. The check meter integrates a plurality of functions together, and can be utilized as the check meter for the electronic mutual inductor as well as a merging unit, a signal collector and a signal converter which are used in field debugging, a high-precision voltmeter, an ammeter, a power meter, a phase meter and an impedance measuring instrument. Therefore, the check meter has high cost performance, and can be widely applied to the electric power field.
