Table 5. DMS-30LCDA-4/20I (Inverse Reading) DIP Switch Settings
The DMS-30LCDA-4/20I is designed to accommodate applications
where an increasing loop current produces a decreasing display
reading. That is, as the loop current is increased from 4mA to 20mA,
the display will read a user determined full-scale positive number
at 4mA and then decrease to “000” at 20mA. The ‘4/20I’ model is
essentially a ‘-4/20S’ model operating in reverse. Table 5 and the
two examples that follow describe the operation of this model in
greater detail.
The fi rst step when confi guring the DMS-30LCDA-4/20I for the fi rst
time, or when changing to a different range, is to set both R3 and
R7 to their full clockwise positions, roughly 22 turns. Next, using the
desired display readings, select the appropriate DIP-switch setting
number from Table 5.

Examples (DMS-30LCDA-4/20I, Inverse Reading)
To turn on a decimal point, place its respective DIP switch to the fully ON position.

DP1
Use DIP-switch setting #3 in Table 5 and enable decimal point DP2
via SW7. Apply 20mA and adjust R3 so the display reads “0.00.”
Apply 4mA and adjust R7 so the display reads “6.00.”
Use DIP-switch setting #2 in Table 5. Apply 20mA and adjust R3 so
the display reads “000.” Apply 4mA and adjust R7 so the display
reads “800.” For these display readings, no decimal points are used.
Set SW6, SW7 and SW8 to OFF.
