Medical fluid system having systems and methods for verifying voltage and analog-to-digital converter measurements

A method for verifying reference voltage and analog-to-digital converter (“ADC”) values during medical fluid treatment, the method comprising:

• initiating, by a computing device having a processor, a pretreatment for a medical fluid treatment system including a control circuit having a plurality of control sensors and a protective circuit having a plurality of protective sensors, wherein the pretreatment exposes the plurality of control sensors and the plurality of protective sensors to common pretreatment conditions;
• receiving, by the computing device, during the pretreatment,
• a plurality of control ADC values corresponding to a plurality of control ADC devices associated with the respective plurality of control sensors, and
• a plurality of protective ADC values corresponding to a plurality of protective ADC devices associated with the respective plurality of protective sensors;
• and
• registering, by the computing device and based on a comparison of a control ADC value with a protective ADC value, an error for one or both of the control circuit or the protective circuit.

A non-transitory computer readable medium for use on a computer system containing computer-executable programming instructions for verifying voltage and analog-to-digital converter (“ADC”) values during medical fluid treatment, the instructions comprising:

• initiating a pretreatment for a medical fluid treatment system including a control circuit having a plurality of control sensors and a protective circuit having a plurality of protective sensors, wherein the pretreatment exposes the plurality of control sensors and the plurality of protective sensors to common pretreatment conditions;
• receiving, during the pretreatment,
• a plurality of control ADC values corresponding to a plurality of control ADC devices associated with the respective plurality of control sensors, and
• a plurality of protective ADC values corresponding to a plurality of protective ADC devices associated with the respective plurality of protective sensors;
• determining, based on the common pretreatment conditions,
• a plurality of actual control reference voltage values corresponding to the plurality of control ADC values, and
• a plurality of actual protective reference voltage values corresponding to the plurality of protective ADC values;
• and
• registering, based on an actual control reference voltage value or an actual protective reference voltage value, and based on a comparison of a control ADC value with a protective ADC value, an error for one or both of the control circuit or the protective circuit.
