4. Measure the CC programming and readback accuracy (take CH1 as an example
in this place) when the output current is the rated output value.
1) Send the following command via the remote interface to select the channel
to be tested (namely the current channel) and set the voltage and current
of this channel (please refer to Table 3-16).
:APPL CH1,8.4,5
/* Select CH1 as the current channel and set the
voltage and current of this channel to 8.4V and
5A respectively*/
Notes:
 The above command is 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 5 command to
set the current of CH1 to 5A.
 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 10 command to set the
current of the channel to 10A.
2) Make sure that the power supply is in CC mode. Read and record the
reading (U
3
) of the multimeter. Calculate the current value I
3
=U
3
/R
M
.
3) Send the :MEAS:CURR? CH1 command via the remote interface; read and
record the returned current value I
4
of the query command.
4) Calculate the CC programming accuracy (|I
3
-I
R
|) and the CC readback
accuracy (|I
4
-I
3
|). Compare them with the specified specifications in Table
3-16. Wherein, I
R
is the rated output current of the channel under test.
5) Send the following command via the remote interface to disable the output
of the channel under test.
:OUTP CH1,OFF
/*Disable the output of CH1*/
5. Repeat steps 1 to 4 to test the CC programming and readback accuracy of CH2
and CH3 until finishing the CC programming and readback accuracy tests of all
channels.
Note: For the multi-channel models of DP800 series, please replace the “CH1”
in the remote commands in steps 3 and 4 with “CH2” or “CH3” to select and set
the corresponding channel.
