The voltage sensed internal to the pO
The voltage control electrode for the pO
The voltage sensed internal to the glucose sensor. The
voltage is maintained at -400 mV ±4% and constant ±1 mV
between calibration cycles with respect to 5_RTN_GLU.
The voltage control electrode for the glucose sensor. The
voltage adjusts such that the signal at GLU_RF is -400 mV
with respect to 5_RTN_GLU.
