: The "AV" version allows both deuterium (D2) and tungsten (W) lamps to be lit at once, enabling high-sensitivity detection across both UV and visible light ranges Documentation & Maintenance Resources

An error has occurred (often a lamp failure or communication break).

190 nm to 700 nm (190 nm to 900 nm for the SPD-20AV). Spectral Bandwidth: 8 nm. Wavelength Accuracy: ±1 nm. Wavelength Reproducibility: ±0.1 nm. Noise Level: AU (under specified standard conditions). Drift: AU/hour (under specified standard conditions). 2. Installation and Initial Setup The system logs cumulative usage

Ensure the unit is properly grounded. According to the instruction manual, connect the power cable securely and turn the power ON.

Avoid placing the instrument directly under air conditioning vents or in direct sunlight, as temperature fluctuations cause baseline drift. Fluidic and Electrical Connections

Finally, lamp management is crucial. The D2 lamp has a finite lifespan (typically 1,000 to 2,000 hours). The system logs cumulative usage, and operators are advised to keep spare lamps on hand to avoid downtime. When replacing the lamp, the manual strictly warns against touching the bulb glass with bare fingers, as oils from the skin can create hot spots and cause premature failure.

Remove the front covers/screws securing the lamp housing access panel. Disconnect the lamp power connector.

Connect the waste tubing to the flow cell outlet port (typically the top port).
