In the back of the respective manuals, there is a chart giving a brief description of the error codes. If more information is needed or an error code is recurrent, it is best to contact Scientific Support for advice to determine if there is a potential device problem. They can provide additional diagnostic advice.
The manual of the next generation 4D Nucleofector™ system does not have the error list included. For adapting the errors faster and adding of new error list with other software versions, we decided to put them online in our supporting pages: 4D-Nucleofector® System Error Codes | Lonza
