In efficiency mode, as the flow and pressure vary the % value on line 3 changes to
indicate the difference from the starting point:
Pressing the record button while in screens 1, 2 or 3 (live data view) will save the
instantaneous flow pressure and temperature values to memory. If there is available
memory the display acknowledges by displaying "SAVED". If there is no available
memory the display warns "MEMORY FULL".
This is screen 4, recorded data review and delete screen:
This display shows a table of captured data points that can be navigated by the 'soft
menu' keys designated on the bottom line.
Clear peaks button becomes the scroll "UP" key.
Pressure unit's button becomes the scroll "DWN" key.
PQ/HP button becomes the "DEL" key.
The 'soft menu' action of these buttons allows the user to scroll up and down the
recorded data table with an option to delete data.
The delete options are indicated by 'soft menu' designators on line 4 and allow either
the last data item or all data items to be erased.
