2 Initial Operation
2.1 Initial Operation
This chapter mainly focuses on three basic tests which should be performed before the operation of the power supply: the
preliminary check, the power-on check, and the output check. The preliminary check is to check if the power supply could run
correctly. The power-on test includes a self-test that checks the internal microprocessors and checks if the user is able to
examine the display at the front panel under the condition of applying power to the supply properly. The output check ensures
that the power supply develops its rated outputs and properly responds to operation from the front panel.
In order to make sure the power supply is in accordance with what is required and have a better command
of power supply features for later use, it is suggested that both the experienced and the inexperienced
users should read this chapter prior to operation
