Setting 4 mA and 20 mA Levels Using Ranging

Screen display: S--4 and S-20

NOTE:

If the 4 and 20 mA levels are programmed as described above, this menu can

be skipped; it overwrites previously entered data for them. Press the

green button ↓ to get to the final menu option, “Lrn”.

This is for setting the 4 mA or 20 mA levels by ranging the instrument to a known target, e.g. the present level in a vessel.

NOTE:

See Figure 4-1 on page 4-3 for a map of the programming menu structure and how to access all the menu options.

To change the 4 mA level:

a)If entering the menu system from the PV display, press the green button ↓ repeatedly until the “S--4” menu option is indicated (see above note.)

b)Ensure the target is the 4 mA level and, with the display indicating that level, press the blue button →.

c)The display indicates the present 4 mA level setting, not the new level reading. If this setting is correct, press the red button ↵ and then the green button to get to the next menu option.

d)Press the blue button → to start editing. The display flashes alternately “4” and the new level reading.

e)Press the blue button → to confirm the new level reading is the new 4 mA level.

f)If the new 4 mA level is correct, press the red button ↵ to save. The display changes to the next menu option.

g)If the new 4 mA level is incorrect, press the blue button → to exit to the menu. The menu option “S--4” re-appears; re-start at step (b) or press ↓ for the next menu option.
