CORRECTIVE ACTIONS
Check that the AC power cord connection is secure.
Power-line dropouts may reset the unit and when
power is restored, the output will be off.
Check the TE module connections. A high
impedance on the TE load can cause the output to
exceed the compliance voltage momentarily. If
enabled with GPIB, this condition will shut off the
output. There are other events or conditions that will
turn the output off if enabled with GPIB. See Output
Off Registers in Chapter 3 for more information.
Check the sensor connections at the module and the
load.
Changing control modes while the output is on will
turn the output off.
Verify output cable is securely connected to output
connector and that the Cable ID jumpers are correct.
