loop inputs, all other DMS-30PC-4/20S meters are supplied with their 4-20mA
negative-input terminals (TB1-2, "-") internally connected to their power supply
ground terminal (TB2-2, “-V”). This single-ended input confi guration is compatible
with most grounded-referenced 4-20mA transmitters.
Applications in which the DMS-30PC-4/20S and its associated 4-20mA
transmitter are connected to a common ground and the transmitter drives two or
more loads (for example, the meter in series with a PLC) must have the meter
connected as the fi rst device in the current loop, that is, closest to the system
ground (see Figure 2). If this is not possible and/or the meter must be connected
in the middle of the current loop, then'-I' suffi x models must be used to provide
the required isolation between the meter’s current loop input and the power sup-
ply ground ("-V"). See Figures 2, 3, 4, and 5 for typical loop connections.

OPERATING AND SETUP INSTRUCTIONS
As shipped, the DMS-30PC-4/20S is factory calibrated to read "000"
for a 4mA input and "1999" for a 20mA input. The following worst-case
procedure assumes the DMS-30PC-4/20S is completely mis-adjusted,
i.e., both potentiometers and the DIP switches are randomly set.
1. Set R7 (gain/span adjust) and R3 (zero/offset adjust) fully clockwise,
2. Set SW1 to ON (up position). See DIP switch setting #3.
3. Apply a precision 4mA input, with proper polarity, and adjust R3 until
4. Apply a precision 20mA and adjust R7 until the display reads "1999".
5. If desired, select the appropriate decimal point by setting either SW5,

with both settings to determine which one offers the better settability. Please
keep in mind that the DMS-30PC meter (from which the DMS-30PC-4/20S is
derived) has an accuracy specifi cation of ±2 counts (max.). Thus, it may not
always be possible to obtain the exact desired display reading.
