occurs, but the effects are small if r1 to r4 are adequately small.
Note
If 4W (four-terminal connection) is used, the source voltage between the Hi OUTPUT and Lo
OUTPUT terminals is greater than the voltage generated at the load. If the source voltage
between the Hi OUTPUT and Lo OUTPUT terminals exceeds the source range, the GS610
cannot generate the voltage correctly, and abnormal load detection may be activated causing
the output to be turned OFF. Be sure that the source voltage between the Hi OUTPUT and
Lo OUTPUT terminals do not exceed the source range of the range setting.
