(CV SOURCE)
WARNING
Before connecting to the measured power supply, make sure the measured power supply is
outage, and there is no voltage in the output end, otherwise it will cause electric spark.
Please connect load according to polarity.
If the load consume too much current, line resistance can't be ignored, recommend to use 4W
remote sensing method to make measurement.

Remote Sensing Connection (4-Wires)
The remote sense terminals of AT861x are connected to the output of the power supply.
Remote sensing compensates for the voltage
drop in applications require long lead lengths
.
Before using remote sensing connections, you must set the 4W to ON state under [SETUP]
page.
