0 to 20 mA
The 0 to 20 mA range corresponds to the hexadecimal values 0000 to 07D0
(0 to 2000). The possible data range is 0000 to 0FFF (0 to 4095). But it is
strongly suggested that the input current must not exceed 30 mA.

Arrangement
Note
When using current inputs, voltage input terminals must be short-circuited
with current input terminals.
