A single, multi-functional probe handles both sample and reagent dispensing. It features vertical crash detection, liquid level sensing (capacitive), and internal/external washing.
If your XL 200 seems to run fine but QC consistently shifts high/low, the manual Chapter 9.4 describes the "Reagent Temperature Delta." The machine does not display an error until the delta exceeds 5°C. Check the peltier cooler resistance—should be 3.2 Ohms.
The manual is structured to provide a progressive guide for servicing the analyzer, typically including:
: Includes proprietary PCB layouts and wiring diagrams essential for electrical troubleshooting. erba xl 200 service manual exclusive
Detailed schematics of hydraulic, pneumatic, and electronic systems.
: Prime washes at the start of the day and cleaning probes with alcohol swabs. Periodic Maintenance
Following mechanical repairs or component replacements, precise alignments must be performed via the engineer-level diagnostic software interface. Probe Alignment (Three-Point Geometry) A single, multi-functional probe handles both sample and
The service manual specifically addresses the following hardware and software features: Service Manual For XL-200 With ISE - v2015.01 PDF - Scribd
The photometric system is the core analytical unit. Degradation of the light path yields erratic calibration curves and poor QC results. Halogen Lamp Replacement The halogen lamp (
Power down the analyzer and disconnect the power cord. Allow the lamp to cool for 15 minutes to prevent burns. Check the peltier cooler resistance—should be 3
Probe blockage, incorrect probe height, or liquid level sensor malfunction.
The main control board features diagnostic LEDs to verify voltage rails: Logic power for microcontrollers. +12V DC: Cooling fans and sensor logic.
Clean the sample and reagent probe exterior with 70% isopropyl alcohol.
Lower the probe into a reaction cuvette. The probe tip must clear the bottom of the cuvette by exactly
A 4-stage cuvette laundry system that washes, rinses, and dries the reaction cuvettes using a combination of wash solutions and vacuum lines.
