X-Rite 400 Series Spectrophotometer

The X‑Rite RM400 (part of the 400 Series) is a handheld, 45°/0° spectrophotometer designed for retail paint operations; it measures spectral reflectance and reports data to a PC via USB or serial. Common failure points in this class include power supply issues (voltage drop or faulty adapter), internal sensor degradation (photodiode drift), and communication errors between the unit and host computer. First‑check diagnostics: verify the AC adapter output against spec, inspect the USB/serial port for loose connections or damage, and review any error codes displayed on the instrument’s screen or in the connected software.[oss-gpt-20b]
