4.3.7 Setting 4 mA and 20 mA levels using ranging (on the 3101)
Screen display: S--4 and S-20
Note
If the 4 and 20 mA levels are already programmed, as described in the section “Selecting the
Lost Echo action (on the 3101)” on page 31, this menu option must 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.
To change the 4 mA level
1. 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).
2. Ensure the target is the 4 mA level and, with the display indicating that level, press the
blue button
.
3. 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. Otherwise, continue with step (4).
4. Press the blue button
. The display flashes alternately “4” and the new level reading.
5. Press the blue button
to confirm the new level reading is the new 4 mA level.
6. Press the red button
to save if the new 4 mA level is correct, or press the blue
button
to not save. Afterwards, depending on the button pressed, either the “S--4”
menu or the next menu appears.
Note
See Figure C-1 on page 102 for a map of the programming menu structure and how to access all
the menu options.
To change the 20 mA level
1. If entering the menu system from the PV display, press the green button repeatedly
until the “S-20” menu option is indicated (see the above note).
2. Ensure the target is the 20 mA level and, with the display indicating that level, press the
blue button
.
3. The display indicates the present 20 mA level setting, not the new level reading. If this
value is correct, press the red button
and then the green button to get to the next
menu option. Otherwise, continue with step (4).
4. Press the blue button
. The display flashes alternately “20” and the new level reading.
5. Press the blue button
to confirm the new level reading is the new 20 mA level.
