FAQs and next steps
FAQs
What should I do if the supply will not power on?
• Make sure that the power cord is fully inserted into the
ac power input socket.
• Ensure that the power supply is connected to a line
voltage circuit that is on.
• Make sure the ac line voltage indicator on the bottom of
the instrument is set for the ac line voltage in your facility.
• Check the fuse on the rear-panel ac power input socket to
determine if it is damaged.
What should I do if the power supply does not read the
voltage or voltages I have set?
• Make sure that the rear-panel mating connector with the
shorting jumpers is inserted into the rear panel when using
the front-panel connectors and using local sensing.
• Ensure that the current limit is not set too low for the load
resistance so the channel is not in the constant current
mode.
Can I still use the front-panel terminals if I want to use
remote sensing?
Yes, you can use the front-panel terminals to supply power
to the DUT. Remove the shorting jumpers on the rear-panel
mating connector and connect the sense terminals to the
same location on the DUT that the front-panel terminals are
connected to.
