channel (range) under test. Make sure that the power supply is in CV mode.
Read and record the reading (U

) of the multimeter.
7. Calculate the voltage variation (namely the CV load effect, |U
1
-U
0
|) and compare
it with the specified specification in Table 2-1.
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 CV load regulation rates of CH2 and CH3 until
finishing the CV 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 CV load regulation rate of
this range. Then, repeat steps 3 to 8 to test the CV load regulation rate of the
other range.
 For the channels that support the Sense function of DP800 series, please
connect DP800, AC power supply, electronic load and multimeter according to
Figure 2-2 and turn on the Sense function of the channel after selecting the
current channel in step 3.
