4.1 Voltage Output Zero Adjustment

While monitoring the voltage between the positive output (+OUT) and
common (COM), and with the pressure port open to atmosphere, or with zero
pressure applied, the zero may be adjusted by turning the zero potentiometer
screw.

For the 5 VDC Full Scale Output, the tolerance on zero and span settings is

±

25mV.  For the 10 VDC Full Scale Output, the tolerance on zero and span

settings is 

±

25mV.  For absolute pressure ranges, the zero should be adjusted

with a full vacuum applied.  See Diagram 5 for nominal “installed” output at
atmospheric pressure for compound pressure ranges.
