command (see Chapter 5).
5 NUMBER RANGE An out of range number was sent. Send a new number within the legal
range.

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.
11 HDW ERR CH 1 Error codes 11 through 14 refer to a specific output where an output

may be defective or the supply may require reprogramming. Refer to the
Troubleshooting Section in the Service Manual.
16 CAL ERROR An error has occurred during calibration. This may be the result of out of
range 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).
17 UNCALIBRATED Unexplained EEPROM error; possibly as the result of incorrect
calibration procedure. Recalibrate as described in Appendix A. If the
problem persists, a hardware failure exists (Refer to the Troubleshooting
Section in the Service Manual)
