Sense Working Mode
When the DUT outputs great currents, the voltage drop on the load leads cannot be
ignored. To ensure an accurate measurement for the output voltage of the DUT, the
load provides Sense (remote sense) working mode.
In this mode, the Sense terminals are directly connected to the output terminals of
the DUT. Remote sensing compensates for the voltage drop caused by the load leads,
ensuring that the output voltage of the DUT is consistent with the input voltage of
the load.
Figure 2-47 shows the Sense connections on the front panel.
Figure 2-47 Sense Connections
Operation Procedures:
1. As shown in the above figure, connect the positive terminal on the front panel of
the load to the positive polarity (+) of the DUT; the positive terminal of the
Sense (S+) to the positive polarity (+) of the DUT. Connect the negative
terminal on the front panel of the load to the negative polarity (+) of the DUT;
the negative terminal of the Sense (S+) to the negative polarity (+) of the DUT.
Do not make a wrong connection.
2. Press Utility to enter the system utility function interface. In the "System" tab,
press the Up/Down arrow key to switch the parameter focus to "Sense", and
then press the Left/Right arrow key or use the knob to enable or disable the
Sense function.
Note: After you enable the Sense function, if the Sense terminals are not
connected to the output terminals of the DUT, then the load cannot accurately
measure the voltage of the terminals in any functions.
