DP800 Performance Verification Manual
3-17
Notes:
 For the single channel model with multiple ranges of DP800 series (DP811A),
please first select Range1, set the parameters of Range1 and measure the CC
programming and readback accuracy of this range in steps 3 and 4. Then,
repeat steps 3 and 4 to test the CC programming and readback accuracy of
Range2 (please replace the “P20V” or “LOW” in the remote commands in
steps 3 and 4 with “P40V” or “HIGH”).
 For the channels that support the Sense function of DP800 series, please
connect DP800, AC power supply, current sampling resistor and multimeter
according to Figure 3-2 and send the remote command
(DP821A: :OUTP:SENS CH2,ON; DP811A: :OUTP:SENS CH1,ON) to turn on
the Sense function of the channel under test before turning on the output of
the channel under test in step 3.
