Examples (0-5V Inputs)
1. Desired display readings are:
ON
0.0V input = "0.00"
5.0V input = "6.00"
12345678
Use DIP-switch setting #3 in Table 1 and enable decimal point DP2
via SW7. Apply 0.0V and adjust R3 so the display reads "0.00".
Apply 5.0V and adjust R7 so the display reads "6.00".
2. Desired display readings are:
ON
0.0V input = "000"
5.0V input = "800"
12345678
Use DIP-switch setting #2 in Table 1. Apply 0.0V and adjust R3 so
the display reads "000". Apply 5.0V and adjust R7 so the display
reads "800". For these display readings, no decimal points are
used. Set SW6, SW7 and SW8 to OFF.
3. Desired display readings are:
ON
0.0V input = ".000"
5.0V input = ".250"
12345678
Use DIP-switch setting #5 in Table 1 and enable decimal point DP1
via SW6. Apply 0.0V and adjust R3 so the display reads "000". Apply
5.0V and adjust R7 so the display reads ".250".

Ā The DMS-20PC-0/5 is optimized for handling 5V signal ranges that are
positioned between ā0.1V and +6.0V. As such, input ranges can be anywhere
between ā0.1V to +4.9V and +1.0V to +6.0V as long as their full range is
5 Volts. The meter's zero/offset potentiometer (R3) has enough adjustment
range to produce a "000" display reading for input signal levels between
ā 0.1V and +1.0V.
Please note the DMS-20PC digital panel meter from which the DMS-20PC-0/5
is derived has an accuracy speciļ¬cation of Ā±2 counts (max.). Thus, it may not
always be possible to obtain the exact desired display readings.

4. Desired display readings are:
ON
1.0V input = "000"
6.0V input = "090"
12345678
Even though this input is positioned between +1.0V and +6.0V,
it still meets the 5V full scale input range listed in the Functional
Speciļ¬cations section. Use DIP-switch setting #8 in Table 1. Apply
1.0V and adjust R3 so the display reads "000". Apply 6.0V and adjust
R7 so the display reads "090". With this type of input, it is advisable
to recheck both input levels to be sure the potentiometer settings do
not affect one another.
0-10V Inputs
While the DMS-20PC-0/5 is optimized for operation with 0-5V inputs,
its versatile input stage can also accommodate most 0-10V applica-
tions. The meter's zero/offset potentiometer (R3) has enough adjust-
ment range to produce a "000" display reading with input signal levels
between ā0.1V and +1.0V. Table 2. summarizes the available ranges
when the DMS-20PC-0/5 is used with 0-10V inputs.
Example (0-10V Inputs)
1. Desired display readings are:
ON
0.0V input = "000"
10.0V input = "500"
12345678
Use DIP switch setting #4 in Table 2. Apply 0.0V and adjust R3 so
the display reads "000". Apply 10.0V and adjust R7 so the display
reads "500".
