Voltage output signal of the HCO
Voltage output signal of the reference sensor. The range is
-60 to 140 mV. Impedance is about 10K ohms.
Signal output of the hematocrit 1 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 the HCT_LF contacts of the hematocrit 1
sensor.
Signal reference of the hematocrit 1 sensor. This sensor
connects to the negative input of the synchronous sampling
differential amplifier on the Contact board.
