↓
repeatedly to edit the flashing digit.

indicate it can be edited.
g) Repeat steps (e) and (f) until the last digit is flashing, and edited as
required.
h) Press the blue button
→
to confirm the new 4 mA level. None of the digits
should now be flashing.
i) If the new value is correct, press the red button
↵
to save. The display
changes to the next menu option.
j) If the new value is incorrect, press the blue button
→
to exit to the menu.
The “

See Figure C-1 on page C-2 for a map of the programming menu structure
and how to access all the menu options.
To change the 20 mA value:
a) If entering the menu system from the PV display, press the green button
↓
repeatedly until the “
20
” menu option is indicated (see above note.)
b) Press the blue button
→
to enter the menu for the 20 mA level. The
display indicates the present value of the 20 mA level.
c) If this value is correct, press the red button
↵

Setting the Output
Damping (The 3101)
Screen display:
d
The damping value is a time constant in seconds, and is applied as smoothing
to the level reading and the output current. A new value may be entered up to
999 seconds. A larger value will have the effect of smoothing out rapid
changes of level, and smooth out the effects of turbulence and ripples on the
liquid surface. (It would be unusual to select a value greater than 30 seconds.)
A value of zero may be edited, in which case no smoothing is applied to the
Current Output and transmitter readings immediately change the output.
NOTE:
Because The Rosemount 3101 transmits nominally at once per second, a
damping time of zero will not necessarily give an immediate response.
