Disable the Von Latch Function
When the input voltage is greater than the set starting voltage (Von), the load
starts to sink the current. When the input voltage decreases and reaches below
the set starting voltage (Von), the load will stop sinking the current. As shown in
Figure 2-45.

Short-circuit Operation
The load can serve as a short-circuit system at the input terminal to test whether the
protection function of the DUT is normal when a short circuit occurs to the output
terminal of the DUT.
Press SHORT on the front panel of the load to cause the load to stay in
short-circuited state. At this time, the SHORT key is illuminated, which indicates that
short circuit function is enabled, and the load is in short-circuited state. "SHORT" at
the top of the main interface is highlighted and active. When the SHORT key is not
illuminated, short circuit function is disabled. At this time, "SHORT" at the top of the
main interface is grayed out and inactive.
When a short circuit occurs to the load in non-CC mode, it will automatically be
switched to its original mode. The maximum short-circuit current for
DL3021/DL3021A is 44 A; and that for DL3031/DL3031A is 64 A.
Note: Enabling the short circuit function in CV mode may cause the load to sink
large amounts of current, which may turn the input off.
Tip
If the load cannot sink the current, please check whether the starting voltage
(Von) has been set. If set, please set it to a minimum value.
