Review voltage outputs from the photometer and temperature sensors to catch component degradation early. 5. Safety and Compliance Precautions
Clean electrodes with Deproteinizer; replace electrode if expired. Clogged probe or faulty capacitance sensor. Perform a probe wash; check the sensor wire continuity. Clot Detected Fibrin or air bubble in the sample probe.
Disconnect the main power cable before opening the electronic racks or replacing the power supply unit (PSU).
Cause: Contaminated or scratched cuvettes in the rotor segment. Service Manual Cobas Integra 400 Plus
Execute the automated daily initialization and fluidic priming sequences. Weekly and Monthly Maintenance
The is the definitive technical blueprint for one of the most versatile clinical chemistry analyzers ever produced. While access is rightfully guarded to ensure safety and precision, understanding its structure—from the interactive Service Action Software to the specifics of FP photometry and ISE calibration—is invaluable for both biomedical engineers and lab managers. Whether you are servicing a unit under contract or maintaining a legacy machine, this manual is the key to unlocking the analyzer's full potential and ensuring reliable diagnostic results.

An integral part of the service documentation is the detailed maintenance schedule. While the Operator’s Manual handles daily "Begin of Day" (BOD) tasks, the service-level documentation covers deeper, scheduled interventions. Clogged probe or faulty capacitance sensor
The Cobas Integra 400 Plus operates with hazardous materials (serum, plasma, stool samples). Safety protocols are critical:
Always use Roche-certified O-rings, syringes, and lamps. Generic alternatives can cause micro-meter misalignments, throwing off the delicate dosing system.
Inspect and lubricate the guide rails of the pipetting arms using manual-approved lubricants. Bi-Annual & Annual Service
