High range current calibration compensation #100
Due to heating up, the resistance of current sense resistor is increasing and cause voltage drop. Therefore in CC mode output current will gradually drop. Such drift cannot be measured with ADC since current control loop is in charge of output regulation and with heated resistor, a lower current need to flow for the same voltage drop that is used by control loop circuit. That drift can be up to -0.4%. But it can also be positive when new set current in CC mode is much lower then previous one and output current will starts to increase as resistor is cooling down.
