Error Messages
This chapter lists the error code of the Agilent B1500.
If error occurs, find solutions in this section and solve problems. However, if
problems still remain, perform self-test.
If the Agilent B1500 fails self-test, contact your nearest Agilent Technologies
Service Center.
If errors occur, error codes are stored in the error buffer. To read the error code and
the error message, use the “ERRX?” command. The output of the error codes is in
the order that they occurred.
Example response by “ERRX?”: 305,”Excess current in HPSMU.; SLOT1”
This response indicates that the error 305 occurs on the slot 1.
NOTE “ERR?” command and “EMG?” command
These commands can be used to read the error code 0 to 999 and the corresponding
error message. If the error code 999 is returned, execute the “ERRX?” command to
read the error code and the error message.
Response of the ERR? 1 command is one of the followings.
• 0: No error. Normal condition.
• XYZ: Error XYZ (100 to 999) occurs.
• aXYZ: Error XYZ (100 to 999) occurs on the slot a (1 to 9).
•10XYZ: Error XYZ (100 to 999) occurs on the slot 10.
If the error 305 occurs on the slot 1, ERR? 1 returns 1305, and EMG? 305 returns
”Excess current in HPSMU.”
