Table 19 Pressure delta setting
Project Effective value Description
Enable Enable / disable
Enable or disable the differential pressure module. When the
differential pressure module is enabled, the differential pressure
module channels will be displayed in the related functions
channel list.
Resolution 4/5/6 The resolution of differential pressure
Range Numbers Differential module measuring range
Calculate type A-B or B-A
For the composite mode of differential pressure module, A and B
represent external pressure module A and external pressure
module B respectively
Real time data
------
or Real time differential pressure value
The real-time differential pressure value is displayed only when
the differential pressure module is enabled and both external
pressure modules A and B are online. Otherwise, the real-time
differential pressure value is displayed as ---------
Zero offset zero offset when zeroing Zero offset when differential pressure module zeroing
External module A Module real time pressure values and units Click to enter to view the module information
External module B Module real time pressure values and units Click to enter to view the module information
The following functions are also supported in the DP module management.
Zero: when enabling the DP module and both external A and B are online, users can perform the zero, the zero offset will
be saved and used for calculating the differential pressure.
Cancel zero: cancel the zero offset when performing the zero operation, set the zero offset to 0.
