7.7.1 Percent pressure
% indicator: shows the current pressure percentage.◆
Sector pointer area: shows the pressure ranges and t◆ he trend of pressure
in a fan shaped pattern.changes -
Note: he differential pressure, gauge pressure, absolute pressure,t
have different displayCompound pressure types s.
Scale bar graph: 0%~100%, the minimum scale is 2%.◆
Scale midpoint: point to 50%.
Figure 7-7-1: Pressure % indication
◆
Example: for the ADT681 with (0~100) kPa, if the current pressure
value is 50kPa, the % indicator is 50%, as figure 7-7-1.
7.7.2 Pressure swing
Pressure swing icon: indicates the pressure fluctuation.◆
Sector pointer area: uses one pointer to show the fluctuation degree of◆
two adjacent separate pressure values.
Scale bar graph: range is (-0.25%~0.25%) FS, the min scale is 0.01%FS.◆
Scale midpoint: point to 0.00%FS position

Example: for the ADT681 with (0~100) kPa, if the current pressure
reading is 50 01kPa and the previous pressure was 50 11kPa..,
the fluctuation degree for 2 seperate pressures is 0 1 FS as figure 7 7 2 shows-.% , -- .
