Agilent Technologies Serials 2934A-01825 to 01829 3023A-01925, Agilent 6031A manual Error Number

Hardware Errors During Operation. If an error does not occur during selftest but after the power supply has been operating correctly for a time, error -240 is placed in the error queue. Most subsequent commands will not be executed and will also cause one or more - 240 errors to be placed in the queue after each command. If your application requires the controller to be signalled if the power supply fails, program the status registers to allow execution errors or device-dependent errors to generate an SRQ to the controller.
