2. Turn on the AC power supply; set its voltage to 230V and frequency to 50Hz.
Note: The voltage setting of the AC power supply in this step should be in
accordance with the value selected by the voltage selector at the rear panel of
DP800.
3. Measure the CC programming and readback accuracy (take CH1 as an example
in this place) when the output current is 0A.
1) Turn on DP800. Send the following commands via the remote interface to
select the channel to be tested (namely the current channel), set the
voltage and current of this channel (please refer to Table 3-16) as well as
enable the output of this channel.
:APPL CH1,8.4,0
/*Select CH1 as the current channel and set the
voltage and current of this channel to 8.4V and
0A respectively*/
:OUTP CH1,ON
/*Enable the output of CH1*/
Notes:
 The above commands are only applicable to the multi-channel models
of DP800. You can also send the :INST:NSEL 1 (or :INST CH1)
command to select CH1 as the current channel, the :SOUR1:VOLT 8.4
command to set the voltage of CH1 to 8.4V and the :SOUR1:CURR 0
command to set the current of CH1 to 0A.
 For the single channel model with multiple ranges of DP800 series
(DP811A), you can send the :OUTP:RANG P20V (or :OUTP:RANG LOW,
or :VOLT:RANG P20V, or :VOLT:RANG LOW) command to select Range1
as the current range and then send the :VOLT 21 command to set the
voltage of the channel to 21V and the :CURR 0 command to set the
current of the channel to 0A.
2) Turn on the digital multimeter; select DC voltage measurement function
and set the range to “Auto”. Make sure that the power supply is in CC mode.
Read and record the reading (U

) of the multimeter. Calculate the current

3) Send the :MEAS:CURR? CH1 command via the remote interface; read and
record the returned current value I

of the query command.
4) Calculate the CC programming accuracy (|I

accuracy (|I
