Chip for correcting detection instrument

The embodiment of the utility model provides a chip for correcting a detection instrument, and belongs to the technical field of chips. The chip comprises: a PCBA board, wherein the PCBA board is provided with a plurality of resistors and a plurality of contacts; wherein the plurality of resistors are distributed in the middle of the PCBA board, and each resistor has a first resistance value or a second resistance value; the plurality of contacts are arranged on the side edge of the PCBA board; each contact is independently connected with a corresponding resistor, and the contacts are used for being connected with an external detection instrument and conducting an electric signal of the detection instrument so as to generate a first voltage on the corresponding resistor; the first voltage is used for enabling the resistor to generate different currents when the resistance value is the first resistance value or the second resistance value. According to the chip for correcting the detection instrument, by adopt
