1. Input Con?guration : The DMS-20PC-0/5 has its input low terminal
(TB1 "LO") internally connected to the power supply ground terminal
(TB2 "–V"). This connection effectively places the meter's input in a
single-ended con?guration. 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
?ow through both the –V terminal and the signal LO terminal.

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.

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.
? T he 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 speci?cations apply to the INPUT HI (TB1 "+HI") connection.

1. Set R7 (full scale span/gain adjust) and R3 (zero/offset adjust) fully
clockwise, roughly 22 turns, and place SW1-SW8 to OFF (down
position).
2. Select DIP switch setting #1 in Table 1.
3. Apply a precision 0.0V input and adjust R3 until the meter's display
reads "000".
4. Apply a precision 5.0V input and adjust R7 until the meter's display
reads "1999". Repeat steps 3 and 4 to make sure the adjustments
do not affect one another.
5. Select the appropriate decimal point by setting SW6, SW7 or SW8 to
