Error messages:
Short Sample
Category:
Analysis Error Probable Cause
1. Blood volume is insufficient.
The required volume of blood has not been aspirated.
2. Dirty piercer or whole blood aspiration line
Corrective Action
1. The required volume of blood has not been aspirated.
Analyze in manual mode or capillary mode.
2. If the “Short Sample” error persists although there is
enough sample in the test tube, it is suspected that the
piercer or the whole blood aspiration line is dirty. Clean it as
follows:
1. Perform the shutdown sequence using CELLCLEAN.
(Refer to Chapter 9: 9.1 Execution of shutdown.)
2. When the shutdown sequence is completed, perform
auto rinse.
3. When the auto rinse is completed and the system enters
Ready status, reanalyze the sample.
4. If dirt cannot be removed completely, pour CELLCLEAN
into the test tubes and analyze these samples in the
sampler mode to clean the piercer and the whole blood
aspiration line.
5. If the error still persists, it is assumed that the piercer is
clogged by clots, replace the piercer. (Refer to Chapter 9:
9.16 Replacing the piercer.)
Note:
If the test tube is dirty or the barcode label is affixed on the
lower area than the specified position, the sampler unit cannot
detect the blood volume. Therefore, even if the blood amount is
insufficient, the aspiration will be performed, and the “Short
Sample” error will occur.
Error messages:
SRV Lower Position ERR
SRV Upper Position ERR
Status:
Not Ready
Category:
Analysis Error Probable Cause
1. Sample rotor valve has malfunctioned.
2. Dirty sample rotor valve
Corrective Action
1. Perform test operation:
Check that no tubing is touching any rotating part(s) of the
sample rotor valve. And press the HELP key on the panel
keypad of the Main Unit. Then select “OK” on the function
menu to check the operation.
2. Clean the sample rotor valve, and execute test operation.
Error messages:
Blood Asp Sensor Error
Status:
Not Ready Probable Cause
1. The sensor that monitors whether blood is being aspirated
normally during sampler operation is defective.
Corrective Action
1. Replace the blood aspiration sensor:
Contact your Sysmex technical representative.
As a tentative measure, alter the sampler stop conditions to
allow sampler operation to continue.
