Figure 3-2 CC Test Connections (Sense) 
 
Notes: 
 
  During the CC tests, make connections according to Figure 3-1 for the normal 
channels (namely the channels that do not support the Sense function) of the 
DP800 series power supply. For the channels that support the Sense function 
(CH2 of DP821A and DP811A), make connections according to Figure 3-2 (note 
to short-circuit the (S+) and (+) terminals, (S-) and (-) terminals of the channel 
respectively) and turn on the Sense function of the channel during the test 
process to measure the specifications under Sense mode.  
  The R
M
 in the figures above is a 4-wire current sampling resistor (please select 
current sampling resistor with suitable resistance according to the test item and 
the channel to be tested). As shown in Figure 3-3, C represents the current 
measurement terminal and S represents the voltage measurement terminal. 
During the test, please make the correct connections.
