Table 5-8. Error Messages

Explanation

This is the response to the ERR? query when there are no errors.

You sent the supply a character it did not recognize.

Format of your number is incorrect. Check number syntax.

Occurs when you send a command the supply does not understand.

Either too many parameters are sent without delimiters or the number representation is incorrect. Follow the Syntax Diagram in Figure 5-2. Check spaces and delimiters.

An out of range number was sent. Send a new number within the legal range.

Computer addressed the supply to talk, but it did not first request data. Send query first then address supply to talk.

Quoted string exceeds the display length of 12 characters. Shorten string to a maximum of 12 characters.

This error may occur if too many numbers are sent. Error #4 or #5 may occur first.

EEPROM is not responding correctly to programming commands. An instrument failure has occurred and service is required.

An output error has occurred in an unknown output. Service is required.

Errors 11 through 14 refer to a specific output where there is an output error. Service is required.

Same as in Error #11

Same as in Error #11

Same as in Error #11

The interface cannot find its model number. There may be a hardware failure or the instrument may require reprogramming. Service is required.

You tried to use either a calibration command with CMODE off or the calibration failed while in CMODE. Enable CMODE and check numbers sent during calibration. Also, there could be a hardware error.

There is an incorrect checksum in the EEPROM possibly as a result of incorrect calibration procedure. Recalibrate, and if the problem persists, your supply has a hardware failure.
