		Table D-2. ERROR Responses
Error Code	Message	Explanation
(ERR? query)	(ERR key)
0	NO ERROR	Indicates there are no errors.

1	INVALID CHAR	You sent the supply a character it did not recognize.

2	INVALID NUM	The format of your number is incorrect. Check syntax (see Chapter 5).

3 or 28	INVALID STR	You sent a command the supply does not understand. Resend a recognizable

		command.
4	SYNTAX ERROR	You sent a command with improper syntax. Check syntax of your command (see

		Chapter 5).
5	NUMBER RANGE	An out of range number was sent. Send a new number within the legal range.
6	NO QUERY	The computer addressed the supply to talk, but it did not first request data. Send

		query first and then address the supply to talk.
7	DISP LENGTH	Quoted string in the DSP command exceeds the display length of 12 characters.

8	BUFFER FULL	May occur if too many numbers are sent. Error code 4 or error code 5 are more

		likely to occur for this condition.
9	EEPROM ERROR	The EEPROM on the GP-IB board is not responding correctly to programming

		commands. An instrument failure has occurred and service is required. Refer to
		the Troubleshooting Section in the Service Manual.
10	HARDWARE ERR	An output error has occurred on an unknown output. Service is required. Refer

		to the Troubleshooting Section in the Service Manual.

11HDW ERR CH 1 Error codes 11 through 14 refer to a specific output where an output error has occurred. Service is required. Refer to the Output Board Troubleshooting section in the Service Manual.

12	HDW ERR CH 2	Same as in error 11.
13	HDW ERR CH 3	Same as in error 11.
14	HDW ERR CH 4	Same as in error 11.
14	HDW ERR CH 4	Same as in error 11.
15	NO MODEL NUM	The supply’s model number cannot be found. The GP-IB Interface board may be
15	NO MODEL NUM
		defective or the supply may require reprogramming. Refer to the
		Troubleshooting section of the Service Manual.
16	CAL ERROR	An error has occurred during calibration. This may be the result of out of range
16	CAL ERROR
		numbers sent. If recalibration (See Appendix A) does not fix this there may be a
		hardware failure (Refer to the Troubleshooting Section in the Service Manual).
