(Only older CytoSenses) 1.09.1 Solution - Increase block size memory if the total particle rate is high enough (but prevent time outs) OR set to 'auto' 1.16 Warning: Pressure difference is high. 1.16.1 Solution - Check if there is something blocking from sample inlet to sheath (filter block, tubing) 1.17 Warning: Inner absolute pressure in fluidics towards outside is high. 1.17.1 Solution - Check if there is something blocking in the fluidics pathways (filter block, cuvette, tubing) 1.21 Warning: Last calibration of sample pump towards analysis date was more than 90 days. (01-Jan-0001) 1.21.1 Solution - Check if the pumped analysis volume is the real volume by weighing 1.23 Warning: FWS-L and -R might indicate an air bubble problem 38% (100%=perfect) 1.23.1 Solution - Pinch valve to get rid of the air bubble or blockage by something different 1.27 Warning: SWS HS : Nr of particles with signal height <10 mV is high (92 %) 1.27.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.27.2 Solution - Decrease, set lower particle sample rate. Maybe caused by an overload of particles/ noise in your sample 1.27.3 Solution - Clean sheath, clean cuvette, clean tubing? (noise can be introduced by dirty walls) 1.27 Warning: FL Yellow HS : Nr of particles with signal height <10 mV is high (90 %) 1.27.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.27.2 Solution - Decrease, set lower particle sample rate. Maybe caused by an overload of particles/ noise in your sample 1.27.3 Solution - Clean sheath, clean cuvette, clean tubing? (noise can be introduced by dirty walls) 1.27 Warning: FL Orange HS : Nr of particles with signal height <10 mV is high (75 %) 1.27.1 Solution - Increase, set higher trigger threshold (to prevent measuring noise) 1.27.2 Solution - Decrease, set lower particle sample rate. Maybe caused by an overload of particles/ noise in your sample 1.27.3 Solution - Clean sheath, clean cuvette, clean tubing? (noise can be introduced by dirty walls)
