Error Codes and Messages

Introduction

This appendix describes the GP-IB error codes that can be readback to the controller and the error messages that can be displayed on the power supply’s front panel. A brief explanation of each code and message is also given. The error codes and/or messages fall into three categories: Power-on Self Test Messages, responses to the ERR? query, and responses to the TEST? query.

Power-On Self Test Messages

The applicable message listed in Table D-1 is displayed on the supply’s front panel if the corresponding function has failed the power-on self test. No error code numbers can be returned for these errors. If any of these error messages appear, refer to the Troubleshooting section in the Service Manual.

Error Responses

Table D-2 describes the error codes and messages that can be generated for various programming, calibration, and hardware errors. The error codes can be read back over the GP-IB in response to the ERR? query. The applicable error message is displayed on the supply’s front panel when the ERR key is pressed. Sending the ERR? or pressing the ERR key clears the error.

Test Responses

Table D-3 describes the codes that can be read back over the GP-IB in response to the TEST? query. The TEST? query initiates a self test of the supply.
