7 Troubleshooting cobas b 221 system
Value flag s
Remedy: o Ensure that sample input is sufficient and homogenous.
o Perform "MSS polarization".
o Perform a wetting routine for MSS.
h [System] > [Utilities] > [Fluid actions] > [Wetting routines].
Flag no. 1015 "Sample pos. error (8)"
Conductivity at Lac sensor inside MSS cassette is too low.
Possible causes: o Unhomogenous sample/calibration solution
o Insufficient sample/calibration solution detected
o Measuring path insufficiently wetted
Remedy: o Ensure that sample input is sufficient and homogenous.
o Perform "MSS polarization".
o Perform a wetting routine for MSS.
h [System] > [Utilities] > [Fluid actions] > [Wetting routines].
Flag no. 1016 "Sample pos. error (9)"
Conductivity at Glu sensor inside MSS cassette is too low.
Possible causes: o Unhomogenous sample/calibration solution
o Insufficient sample/calibration solution detected
o Measuring path insufficiently wetted
Remedy: o Ensure that sample input is sufficient and homogenous.
o Perform "MSS polarization".
o Perform a wetting routine for MSS.
h [System] > [Utilities] > [Fluid actions] > [Wetting routines].
Flag no. 1017 "Sample pos. error (10)"
Conductivity at MSS sensor input was too low after positioning the sample/
calibration solution in the measuring chamber.
Possible causes: o Unhomogenous sample/calibration solution
o Insufficient sample/calibration solution detected
o Measuring path insufficiently wetted
Remedy: o Ensure that sample input is sufficient and homogenous.
o Perform "MSS polarization".
o Perform a wetting routine for MSS.
