4.3 current output Zero adjustment
While monitoring the current output, and with both pressure ports open to atmosphere, the zero may
be adjusted. For unidirectional pressure ranges, turn the zero adjustment screw until a reading of 4 mA
(±.08 mA) is achieved. For bidirectional ranges, set zero to 12 mA (±.08 mA).
4.4 current output span adjustment
Span or full scale output adjustments should only be performed by using an accurate pressure standard
(electronic manometer, digital pressure gage, etc.), with at leads comparable accuracy to the 230 series
(±.25% full scale). With full range pressure applied to the high pressure port (reference port open to
atmosphere), adjust span to achieve 20 mA (±0.08 ma) output.
Example 1: Unidirectional pressure range of 0 to 1 PSI
Apply 1 PSI, adjust output to 20 mA
Example 2: Bidirectional pressure range of ±.5 PSI
Apply .5 PSI, adjust output to 20 mA
