6. Set the electronic load to work in CV mode and adjust the voltage of the
electronic load to the rated output voltage (please refer to Table 1-1) of the
channel (range) under test. At this point, the channel under test of the power
supply is still in CC mode and is near full load output. Read and record the
reading (U
1
) of the multimeter.
7. Calculate the current variation (|U

specified specification in Table 3-1.
8. Press the On/Off key corresponding to the channel under test at the front
channel to disable the output of the channel under test.
9. Repeat steps 1 to 8 to test the CC load regulation rates of CH2 and CH3 until
finishing the CC load regulation rate tests of all channels.
Notes:
 For the single channel model with multiple ranges of DP800 series (DP811A),
please first select a range and set the corresponding parameters of this range
in step 3 and then perform steps 4 to 8 to test the CC load regulation rate of
this range. Then, repeat steps 3 to 8 to test the CC load regulation rate of the
other range.
 For the channels that support the Sense function of DP800 series, please
connect DP800, AC power supply, current sampling resistor, electronic load
and multimeter according to Figure 3-2 and turn on the Sense function of the
channel after selecting the current channel in step 3.
