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-

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 speci?cation of ±2 counts (max.). Thus, it may not
always be possible to obtain the exact desired display readings.
