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.
