Error messages:
RET Error
Category:
Analysis Error Probable Cause
1. Abnormal sample
2. Clogging, bending or disconnection at RET dye solution
and diluent line tubing
Corrective Action
1. Perform the analysis again.
2. Check the dye solution tubing and the reagent amount.
Error messages:
WBC/BASO-CH Error
DIFF-CH Error
NRBC-CH Error
Category:
Analysis Error Probable Cause
1. Clogging or dirt at optical detector block flow cell
2. Abnormal short sample (Insufficient samples or mixing of
air bubbles, etc.)
3. Abnormal sample (Platelet coagulation or sedimentation of
cold protein, etc.)
Corrective Action
1. Clean the flow cell of optical detector block.
(Refer to Chapter 9: 9.11 Cleaning the flow cell in the
optical detector block.)
2. Perform the analysis again.
3. Check the sample using smear or visually.
Error messages:
RBC-CH Error
PLT-CH Error
Category:
Analysis Error Probable Cause
1. The number of RBC/PLT channel particles exceeds the
upper limit of display range because of external noise.
Corrective Action
1. Interrupt the noise source.
Keep the noise source away from the Main Unit.
2. Perform the analysis again.
Error messages:
RET-CH Error
Category:
Analysis Error Probable Cause
1. Abnormal sample
2. Sample rotor valve has clogged.
3. Clogging or dirt at optical detector block flow cell
4. Air bubbles in optical detector block flow cell
Corrective Action
1. Perform the analysis again.
2. Clean the sample rotor valve.
3. Clean the flow cell of optical detector block.
(Refer to Chapter 9: 9.11 Cleaning the flow cell in the
optical detector block.)
4. Remove the air bubbles from the flow cell of optical detector
block.
