Analog Pressure Output
The analog pressure output indicates the operating pressure of the pump. The
pressure output is set to 50 mV/MPa (5 mV/14.51 psi). To monitor the pressure,
connect the pressure output to a recorder or an A/D converter. These are the pin
assignments for the 2-pin Cinch connector (P/N 8005.9001A):
