Voltage Output Span Adjustment; Current Output Units; Current Output Span Adjustment - Setra Systems 223 Operating Instructions Manual

4.2 Voltage output span adjustment

Zero adjustment must be performed prior to span adjustment. Span adjustment should only
be performed by use of an appropriate pressure standard (electric manometer, digital pressure
gauge, etc) with at least 4X the accuracy of a model 223. The span may be adjusted by turning
the span potentiometer while full scale pressure is applied to the pressure port.
4.3 Voltage output units
Transducer zero may be adjusted by monitoring the current output while turning the zero
potentiometer screw. The adjustment should occur with atmospheric pressure applied for
gage transducers. Absolute and compound transducers should be adjusted while a full
vacuum is applied. Compound transducers may alternatively be adjusted at atmospheric
pressure using the values in diagram 6.
WARNING: Pressure should be applied with inert gases or clean air only. For transducers
with ATEX Ex marking, no adjustment should be made in the presence, or potential for,
hazardous atmosphere.
