Connecting Loads to a Voltage Output of an Isolated AO over a
Four-Conductor Connection
Two-Conductor Connection of Loads to a Voltage Output
In the case of a two-conductor connection, connect Q
V
to S+ and M
ANA
to S– on
the front connector. However, this will not produce the accuracy of a four-conductor
connection.
Connect the load to terminals Q
V
and to the reference point of the measuring
circuit M
ANA
of the module.
