I want to use our lab power supply to power up a CNC machine we have that has a bad power supply. When I tested the outputs from the "off" state, to "on" state, the dialed in voltage seemed to spike, them settle down to where I wanted it. I am concerned that voltage spike could damage something. It is also possible that my meter was picking up on something else and it would be nothing to be concerned about. I have one ch set to 24V and it spiked to 30V when turned on.
