Analyte monitoring device calibration

A system configured to calibrate multiple analyte monitoring devices, the system comprising:

• a reference bath containing a solution having a known analyte concentration;
• a calibration board comprising:
• a plurality of electrodes, each of the plurality of electrodes being connected to a different analyte monitoring device of a plurality of analyte monitoring devices;
• and
• a single ground electrode that contacts the solution of the reference bath;
• a voltage source that applies voltage to the plurality of electrodes;
• and
• a plurality of current meters, each of the plurality of current meters monitoring a current flowing from a respective one of the plurality of electrodes to the single ground electrode via a respective one of the plurality of analyte monitoring devices.

A method comprising:

• applying a voltage to an analyte monitoring device connected to a calibration board while a sensor of the analyte monitoring device and a single ground electrode of the calibration board are in contact with a reference bath;
• measuring, for the analyte monitoring device, a current that flows through the sensor to the single ground electrode as a result of applying the voltage;
• and
• generating calibration results for the analyte monitoring device based on the current.
