Claim 5:
6. The current calibration method of claim 5, wherein in step S02, specifically comprising:
S021: the SPI bus adjusts the output voltage (Vb) of the VBIAS power supply and an output voltage (Va) of a corresponding power supply channel of the n power supply channels, to Va−Vb=x; and records a value of a output current (Ia) of the corresponding power supply channel and a value of a measured current (Ib) of the ammeter; Wherein, x is greater than 0, and the value of the output current (Ia) is a current value to be calibrated;
S022: repeating step S021 Y times to obtain Y values of Y output currents (Ia) of Y power supply channels and Y values of Y measured currents (Ib) of the ammeter; Y is an integer greater than 0.
