Sense Working Mode
When the output current of the power supply is high, the voltage drop on the load
lead cannot be ignored. To make sure that the load can acquire accurate voltage
drop, CH2 of DP821A and DP811A (which can provide 10 A output current) provide
the Sense (remote sense) working mode. In this mode, the voltage is sensed at the
load rather than at the power supply’s output terminals. It allows the system to
automatically compensate the voltage drop in the load leads so as to ensure the
specified output value can be consistent with the voltage received by the load.
The Sense connection method at the front panel is as shown in the figure below.
Operation Steps:
1. Connect the channel output terminals and Sense terminals at the front panel of
the instrument to both ends of the load, as shown in the figure above. Pay
attention to the polarity when making connections.
2. For DP821A, after selecting CH2 (8V/10A), press Sense to enable the Sense
function.
For DP811A, after selecting the desired range, press Sense to enable the Sense
function.
Tip
 When outputting a high current, use as short as possible and twisted load
leads in order to obtain the best output characteristics.
 Please use a twisted-pair as the Sense lead as possible as you can and the
leads should not be twisted with the load leads.
