Applications
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".

âž‚ The DMS-20PC-0/5 is optimized for handling 5V signal ranges that are
positioned between –0.1V and +6.0V. As such, input ranges can be
anywhere between –0.1V 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 – 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 specification of ±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
Specifications 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
applications. The meter's zero/offset potentiometer (R3) has enough
adjustment range to produce a "000" display reading with input signal
levels between –0.1V 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".
