Error Messages

Execution Error List

An error in the range [-299, -200] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in the class causes the execution error bit (bit 4) in the Event Status Register to be set.

Execution errors are reported by the device after rounding and expression evaluation operations have taken place.

Table B-2	Execution Error List
Error Code	Error Message Description
-200	Execution Error
	This is the generic syntax error for devices that cannot detect
	more specific errors. This code indicates only that an Execution
	Error as defined in IEEE 488.2, 11.5.1.1.5 has occurred.
-203	Command protected
	Indicates that a legal password-protected program command or
	query could not be executed because the command was
	disabled. Check the calibration state.
-220	Parameter error
	Indicates that a program data element related error has occurred
-221	Setting conflict
	Indicates that a legal program data element was parsed, but
	could not be executed due to the current power supply state.

The following list is not exhaustive but does cover some of the more common conditions that may contribute to this error:

•OVP/UVP Set Points —The OVP and UVP limit the setting of the voltage set point so that you cannot accidentally trigger these alarms by changing the set point outside of their range. Conversely, setting the OVP set point to be less than the voltage set point will also trigger this error.

•Changing the Set Point while in APG mode —The user will be unable to change the set point while APG is being used to control that parameter: voltage or current.

•Autosequence Programming —Various conflicts can occur while using Autosequence programming; for example, using the trigger command while the program is running will result in this error.

•Calibration mode —When in calibration mode, certain settings will cause an error.
