| Symptom | Likely Cause | Solution | |---------|--------------|----------| | Won’t power on | Dead battery | Charge overnight | | Erratic O₂ reading | Sensor depleted | Replace sensor (life ~2 yrs) | | H₂S/CO reading in fresh air | Zero drift | Perform fresh air zero | | Combustible sensor saturation | High gas exposure | Let sensor recover in clean air |

Environmental temperature exceeds operating limits, or the internal Peltier element is malfunctioning.

Official and community-hosted documents are available for technical reference:

Run standard control serums to check for wavelength calibration consistency. 5. Troubleshooting Common Error Codes Observation / Error Probable Root Cause Recommended Action High Water Blank Absorbance Contaminated flow cell or dirty water source. Clean flow cell with detergent; use fresh deionized water. "Lamp Low Signal" Error Halogen lamp aging, misaligned, or burned out. Replace the 12V/20W halogen lamp module. Inconsistent Result Volumes Air leak in peristaltic pump or clogged probe tip. Inspect pump tubing connections; clear probe blockages. Temperature Unstable Peltier failure or blocked airflow vents. Check room air conditioning; clear dust from cooling fans. Printer Jammed / No Text Thermal paper loaded backwards or empty roller. biosystems bts 350 user manual

Inspect the exterior casing for any signs of physical transit damage.

Users navigate the software via the touch screen. Key menu options include:

Confirm that the room climate control is operational. Allow the instrument an additional 10 minutes to stabilize. 8. Safety Precautions and Disposal Guidelines Biological Hazard Mitigation | Symptom | Likely Cause | Solution |

Access routine testing, calibration, and patient results.

Regular maintenance preserves the lifespan of the optical path and ensures the accuracy of patient diagnostics. Daily Maintenance

Keep the analyzer away from direct sunlight, excessive dust, and electromagnetic interference (e.g., large centrifuges or refrigerators). Replace the 12V/20W halogen lamp module

Correct laboratory conditions prevent physical damage and baseline drift in optical readings. Environmental Conditions

Regularly review QC results for drift or systematic errors. 5. Maintenance and Troubleshooting A key benefit of the Go to product viewer dialog for this item. is its low maintenance cost, but routine care is essential. 5.1. Regular Maintenance

Decontaminate using a 5% sodium hypochlorite (bleach) solution or a laboratory-grade protein cleaning solution. Flush thoroughly with 10 mL of distilled water afterward. Peristaltic Pump Tubing

Switch on the power button located on the back or side panel.
