2.5 Dynamic test operation
Dynamic test operation can be repeatedly switched between two kinds of load setting current
or voltage, this function can be used to test the dynamic characteristics of power supply. Before st
arting the dynamic test operation, it is necessary to set the parameters related to the dynamic test.
The specific parameters include: dynamic load state, A value, A value pulse width time, B value p
ulse width time and dynamic test mode. The setting interface and test interface are shown in Figur
es 2.5.1 and 2.5.2, respectively.
Parameter setting interface operation instructions
