Setting the 4 and 20 mA
Levels Using Ranging
(The 3102 and The 3105)
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. 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-2 on page C-3 for a map of the menu structure and how to
access the menu options.

↵ to exit to the menu.
(The “SEt 4” re-appears. To get to the “SEt 20” menu option, press
↓.)
d) With the transmitter aimed at a target a distance away equivalent to the
4 mA level, press the blue button
→ to start the ranging. The display
alternately flashes “4” and the live measurement reading.
e) Press the blue button
→ to confirm the PV at 4 mA is to be changed to the
same value as the live measurement reading.
f) If the new PV at 4 mA value is correct, press the red button
↵ to save and
then the green button
