Screen display: (SEt 4 and SEt 20)
If you have already programmed the 4 and 20 mA levels as above, you do not need to enter this
menu; it overwrites previously entered data for them.
All the programming is now complete and you should press the red button
to exit the
programming menu and return to the main PV display.
If, however, you wish to set the 4 or 20 mA level by ranging the instrument to a known target -
perhaps the level in the vessel at this time - then press the blue button
to enter this menu.
Note
This “SEt 4” menu option is in the programming menu. See Figure C-1 on page 76 for
a map of the menu structure and how to access the menu options.
