Voltage Output
Pressure signal analog voltage is available between the Signal Out line (pin 9) and Signal
Ground line (pin 10) of J1. The voltage is a 1V/decade output representing the Log of the
pressure, offset to a range between 1 and 9 VDC (Table 7).
0.5 V output indicates pressure below operating range of the Eyesys Mini-BA
