Beckman Coulter Met One R4800 / R4900
Beckman Coulter · Model Met One R4800 / R4900
Easy Integration MET ONE R4800 series remote air particle counters use standard RS-485 serial communications MET ONE R4900 series remote air particle counters use industry standard 4-20mA interface Stainless steel enclosure compatible with most process environments Compact size for easy mounting with a vacuum source, DC power & communication line Data Management MET ONE R4800 & R4900 counters respond to simple ASCII command instructions, including start, stop and report counts, send location number, etc. Reporting data includes counter status & particle counts in two size ranges Multiple display options via continuous monitoring feature (Particle Vision® Online & CIMScan® software Operation User-programmed alarm level detects high counts on first channel triggering an alarm Auto alarm reset at start of the next count cycle Long-life laser technology for superior performance & extended service life No fan allows proximate placement to sensitive processing areas Flexible Sensitivity ranges of 0.5um & flow rates of 1.0 cfm Onboard status indicator sets signal at connector for alarm Stay resident RS-485 configuration programming (count/hold times, alarm level/delay & scaling) maintained through power cycles Sensor resistant to vaporous hydrogen peroxide (VHP)
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not power on or unexpected shutdown
HighSymptoms: The patient monitoring is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not power on
- Confirm the outlet, mains lead and fuse.
- Try on battery, then on mains only, to isolate the supply.
- Look for a power indicator or POST code.
- Replace the fuse / battery / power supply as isolated.
- Run the self-test after any repair.
Symptom: Fails self-test or calibration
- Note the exact failure message / code.
- Power-cycle and repeat the self-test.
- Verify against a reference / simulator where one applies.
- Recalibrate per the service manual.
- Refer the affected board for service if it will not hold calibration.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Beckman Coulter identified that LDL Cholesterol OSR6x96 is not meeting the performance claim listed in the Instructions for Use (IFU). LDL Cholesterol reagent showed clinically significant interference due to triglyceride concentration up to 1500 mg/dL may cause a maximum positive bias of up to 28.8% in low LDL Cholesterol samples (concentration 80 mg/dL) and up to 11.02% in high LDL Cholesterol samples (concentration 160mg/dL).
- RECALL
Access Thyroglobulin reagent lot 439163 may generate erroneously high patient results. Falsely increased Access Thyroglobulin results may lead a physician to pursue unnecessary diagnostic imaging studies and/or inappropriate therapy adjustments in patients being monitored for residual or recurrent thyroid cancer.
- RECALL
Software error: This field action was initiated after Beckman Coulter determined that the CXP software does not refresh the dataset automatically under certain circumstances. The User documentation does not clearly state that the user should refresh the dataset after changes are made.
