Claim 0:
1. A current output module comprising:
a current output section configured to output a current;
an AD conversion circuit configured to convert a detection voltage, which is a voltage according to the current output from the current output section, into a digital value;
a controller configured to control a current output from the current output section on the basis of the digital value of the detection voltage output from the AD conversion circuit; and
a reference voltage generator configured to generate a plurality of reference voltages,
wherein the controller comprises:
a processor configured to cause the AD conversion circuit to convert each of the plurality of reference voltages into a digital value; and
a corrector configured to calibrate the AD conversion circuit on the basis of each digital value obtained by conversion of the plurality of reference voltages.
