● Speed and flow
The processor emits the speed via port P1.1 and the flow via port P1.2 to the dialysis monitor.
● Pressure measurement
The differential measuring amplifier for the pressure transducer is formed by IC 6 (1/2/3) and IC
6 (5/6/7). Via the A-D converter input AN7, the measuring signal is read in by the processor and
calibrated to zero point and slope via the software. Subsequently, the measuring signal is pulse-
width-modulated via port P1.3 and emitted to the monitor via a following D-A converter IC 11 (5/
6/7).
