Description
Positive signal output of the hematocrit 2 sensor. This sensor
connects to the positive input of the synchronous sampling
differential amplifier on the Contact board. The amplifier
circuitry measures the impedance (conductance) between
the HCT_HF and HCT_LF contacts of the hematocrit 2
sensor.
Signal reference of the hematocrit 2 sensor. This sensor
connects to the negative input of the synchronous sampling
differential amplifier on the Contact board.
