For questions related to instrument data quality we always need to know the following:

• Instrument type and serial number (e.g. LISST-Portable|XR sn 785)
• The raw data files(s) you are concerned about. Refer to your instrument manual if you don’t know exactly which files are raw data files.
• For a LISST-100X, -STX, and Deep, the background (zscat) file you used for data processing.

For hardware questions we always need to know the instrument type and serial number. Please provide us a detailed description of the issue and what you were doing at the time when you discovered the issue.
