Setra System Model 217 - Manual (Page 5)

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 potentiom-
eter 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 ±50mV. For absolute pressure ranges, the zero should
be adjusted with a full vacuum applied. See the Diagram 5 below for nominal “installed” output at atmospheric
pressure for compound pressure ranges.
4.2 Voltage Output Span Adjustment (Complete the zero adjustment before setting span.)
Span or full scale output adjustments should only be performed by using an accurate pressure standard (electronic
manometer, digital pressure gauge, etc.), with at least comparable accuracy to the 217 transducer (±0.25% FS). With
full range pressure applied to the pressure port, the span may be adjusted by turning the span potentiometer screw.
The span (full scale) output is factory set to within ±25mV for 5 VDC output or ±50mV for 10 VDC FS output.
