Set Current
The constant current in CC+CV mode. The default unit for the current is A.
(1) In the main interface, press Current to switch the parameter focus to "Current".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For setting
methods, refer to the descriptions of the help information or refer to the
descriptions in "Parameter Setting Method".
Set C_Range
The working ranges of current in CC+CV mode are as follows. Different models have
different ranges.
DL3021/DL3021A: low range (0 to 4 A); high range (0 to 40 A)
DL3031/DL3031A: low range (0 to 6 A); high range (0 to 60 A)
(1) In the main interface, press C_Range to switch the parameter focus to
"C_Range".
(2) Press C_Range to switch the current working range. You can also use the
Left/Right arrow key or the knob to switch it.
Note:
The low range provides better resolution and accuracy at low current settings.
If the set current value is greater than the maximum value of the low range, you
must select a high range.
Before switching the current range, please disable the channel
input to avoid causing damage to the instrument or the DUT.
Set Voltage
The constant voltage in CC+CV mode. The default unit for the voltage is V.
(1) In the main interface, press Voltage to switch the parameter focus to "Voltage".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For setting
methods, refer to the descriptions of the help information or refer to the
descriptions in "Parameter Setting Method".
Set V_Range
Working range for the voltage in CC+CV mode. Two ranges are available: low range
In CC+CV mode, when the set load current is greater than the current output
from the DUT, short circuit occurs to the DUT.
In CC+CV mode, when the set load voltage is greater than the voltage
output from the DUT, broken circuit occurs to the DUT.
