Beckman Coulter DxH 500
Beckman Coulter · Model DxH 500
98.5% uptime. Quality clinical results from as little as 12 µL of sample. Change all three reagents in less than five minutes. Repeat testing on the same sample without another draw. Perform any command in three touches or less. Supports your efforts to go paperless with bidirectional LIS Interface. On board storage of 30,000 patient results.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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 laboratory & diagnostics 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.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
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
Specific diluent lot numbers showed that conductivity, osmolality, and pH were out of manufacturing specifications.
- RECALL
A manufacturing defect on the amplifier board of the Flow Cytometers my cause signal loss and/or signal drifting resulting in absence of data or a population shift in the data plots. This can impact patient results for any application.
- RECALL
Beckman Coulter has received an increased number of complaints related to Hemoglobin (HGB) on UniCel DxH 800 and DxH 600 Coulter Cellular Analysis Systems. The use of the DxH Diluent lots listed in the recall notice may eventually result in a compromised HGB chamber.
- RECALL
Beckman Coulter is recalling Coulter DxH Diluent because it may be associated with elevated platelet (PLT) background counts between 3-7 x 10(3) cells/uL. This will result in failed Daily Checks on the UniCel DxH 800 and DxH 600 Coulter Cellular Analysis Systems.
- RECALL
Labeling provided by two integrated software systems are not clear enough to avoid potential demographic and sample type mismatches under certain conditions.
- RECALL
Software error: The recall was initiated after Beckman Coulter identified that the CXP User documentation does not adequately characterize the use of the Live Gate feature. The primary use of a Live Gate is for the international removal of unwanted events, such as debris. The data outside of the Live Gate will not be stored to the final listmode file, this reducing the data set size. The softwa
- RECALL
The ratio parameter assignments (numerator and denominator) of a protocol may inadvertently change after the Parameter Selection Dialog box is accessed. Issue limited only to protocols utilizing the Ratio parameter such as LeukoSure and DNA Cell Cycle.
- RECALL
Two workflow scenarios associated with renaming regions may produce incorrect results.
- RECALL
Mis-identification-If a panel or protocol is added to an existing worklist but the tube location is not specified, the CXP Acquisition software will run the last specified tube through the remaining protocols and will generate results and printouts of these runs leading to a Mis-Identification condition.
- RECALL
Beckman Coulter has determined that under certain conditions a system error generated during a Pause and Rotate routine may result in a sample misidentification with a risk of reporting erroneous results.
- RECALL
Beckman Coulter has confirmed an issue associated with the predilute mode of the COULTER LH 500 Hematology Analyzer. The workstation may display, transmit, and / or print an erroneous result or an incorrect dilution factor with a predilute sample result.
