Ordering Information
The DMS-20PC-0/5 can also be used in most 0-10V applications. See the section
on 0-10V inputs for more information. See Note 3 on Table 1.
INPUT LO (TB1 "–LO") is internally connected to the power return (TB2 "–V").
Overvoltage specifications apply to the INPUT HI (TB1 "+HI") connection.

TECHNICAL NOTES
OPERATING AND SETUP INSTRUCTIONS
As shipped, the DMS-20PC-0/5 is factory calibrated to read "000" for
a 0.0V input and "1999" for a 5.0V input. The following worst-case
procedure assumes the DMS-20PC-0/5 is completely mis-adjusted, i.e.,
both potentiometers and the DIP switches are randomly set.
1. Set R7 (full scale span/gain adjust) and R3 (zero/offset adjust) fully
2. Select DIP switch setting #1 in Table 1.
3. Apply a precision 0.0V input and adjust R3 until the meter's display
4. Apply a precision 5.0V input and adjust R7 until the meter's display
5. Select the appropriate decimal point by setting SW6, SW7 or SW8 to
(TB1 "LO") internally connected to the power supply ground terminal
(TB2 "–V"). This connection effectively places the meter's input in a
single-ended configuration. In some applications, single-ended inputs
can cause ground-loop induced errors (the meter's display becomes
unstable or bounces). This occurs because the LED drive currents
flow through both the –V terminal and the signal LO terminal.
If suspected ground-loop errors are encountered, and the input signal
LO terminal is externally connected to –V somewhere else in the
system, try removing the connection to TB1 "LO". Inputs which have
no ground-return connection to –V (commonly referred to as "floating
inputs") must have their most negative potential tied to TB1 "LO".
Please consult DATEL for more information.
Applications which require electrical isolation between the input
signal source and the system power supply must use a separate
transformer-isolated supply to power the meter.
the DMS-20PC-0/5 must be secured to the panel with DMS-BZL4
bezel assemblies (see the Mechanical Specifications section for more
information).

position).
reads "000".
reads "1999". Repeat steps 3 and 4 to make sure the adjustments
do not affect one another.
ON (DP1, DP2 or DP3 respectively).
NOTE: The "000" to "1999" display readings referred to in the
instructions above are for illustrative purposes only. If other display
readings such as "000" to "1200" are desired, refer to the DIP-
Switch Settings Tables for SW1-SW4 settings. (SW5 is reserved for
future use, it has no affect on display operation.) The initial setting
of R3 and R7 fully clockwise is recommended in the adjustment
procedure for all the following examples.
