FL Red HS: PMT level is 0 -------------------------- Warnings info -------------------------- 1.05 Warning: Your effective analysis volume is low compared to the pumped analysis volume 1.05.1 Solution - Set blocksize memory in CytoUSB higher, used=4k (default=4k) e.g. to 8k 1.09 Warning: This (default) low block size of 4kB in CytoUSB will decrease the effective analysis volume 1.09.1 Solution - Increase block size memory if the total particle rate is high enough (but prevent time outs) 1.15 Warning: Pressure difference is high. 1.15.1 Solution - Check if there is something blocking from sample inlet to sheath (filter block, tubing) 1.16 Warning: Inner absolute pressure in fluidics towards outside is high. 1.16.1 Solution - Check if there is something blocking in the fluidics pathways (filter block, cuvette, tubing) 1.17 Warning: Last calibration of sample pump towards analysis date was more than 90 days. (01-Jan-0001) 1.17.1 Solution - Check if the pumped analysis volume is the real volume by weighing 1.18 Warning: FWS-L and -R detector signals are quite different (ratio 1.4816(1=perfect)) and might indicate an alignment problem 1.18.1 Solution - Probably you have an air bubble in your system. Pinch valve to get rid of it 1.18.2 Solution - Improve alignment of FWS-L and -R detector towards sample core 1.19 Warning: FWS-L and -R might indicate an air bubble problem 18% (100%=perfect) 1.19.1 Solution - Pinch valve to get rid of the air bubble or blockage by something different 1.23 Warning: SWS HS : Nr of particles with signal height <10 mV is high (83 %) 1.23.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.23.2 Solution - Decrease, set lower particle sample rate. Maybe caused by an overload of particles/ noise in your sample 1.23.3 Solution - Clean sheath, clean cuvette, clean tubing? (noise can be introduced by dirty walls) 1.23 Warning: FL Yellow HS : Nr of particles with signal height <10 mV is high (93 %) 1.23.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.23.2 Solution - Decrease, set lower particle sample rate. Maybe caused by an overload of particles/ noise in your sample 1.23.3 Solution - Clean sheath, clean cuvette, clean tubing? (noise can be introduced by dirty walls) 1.23 Warning: FL Orange HS : Nr of particles with signal height <10 mV is high (73 %) 1.23.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.23.2 Solution - Decrease, set lower particle sample rate.
