Note
Connect as shown below when the same power supply is used for input points 1
and 2.
Connect resistors from the shield to the negative terminal. This connection re-
sults in an accuracy of ±1%.
Abide by the following precaution when the same power supply is used for the
input points.
Connect the wiring as shown in the diagram above when the same power supply
is used for input points 1 and 2.
