I was performing the Holmium Oxide test in Lab Advisor for a 1220 Infinity LC VL and it was aborted with this message "holmium filter test in FW timed out!". At first, I thought it was related to some FW issue so I updated the FW to the last one released in December (B.07.28 ) and perform the test. It was aborted by the system again.
I would like to know the causes of this problem, and if the solution involves replacing the holmum oxide filter. It is important to say that the other VWD tests (Calibration, filter/grating, Intensity, Cell, Noise...) were performed and passed without problem.
By the way, I would like to know if there is a special procedure manual for FSEs in order to remove/install 1220 parts such as Pump drives, Sample Transport Units or Optical Unit components as the Service manual only shows the exchanging of parts like needles, seats, rotor and pump seals...
Thank you for your help!
