FAQ
What should I do if the supply will not power on?
1.
Make sure that the power cord is fully inserted into the AC power
input socket.
2.
Ensure that the power supply is connected to a line voltage circuit
that is on.
3.
Make sure the AC line voltage indicator on the bottom of the
instrument is set for the AC line voltage in your facility.
4.
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?
1.
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.
2.
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 jacks 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.
