Blow-off Adjustment
The volume of air during the blow-off function to release the
workpiece can be set by turning the needle adjustment up
or down. Access the needle adjustment through opening of
protective cover (topside).
Units of Measure
The pressure sensor has an LED function that indicates
the degree of pressure in the system. The units can be
changed, but are factory set to inHg (inches of Mercury).
The relationship of inHg with a gauge pressure scale and
absolute pressure scare are in the following table. In general,
the negative sign on the gauge pressure scale is assumed
and may or may not be noted on documentation.
