Figure 3-24 When Von Point sets to 0V without Protection
(2) When the Von Point is set to 0V and protection is selected for LVP during "LOAD ON",
the Electronic Load starts current loading when the SW is off and the external voltage is
over the protection voltage. Current overshoot will not occur under this circumstance as
shown in Figure 3-25 .

(3) When the Von Point is not set to 0V and protection is selected for LVP during "LOAD
ON", turn off the SW after it is turned off a period of time and then turn the SW off again.
It will not perform current loading if the power is lower than the default protection voltage
as shown in Figure 3-26. The loading state restores when the SW is off and the power
is larger than the default voltage.
