  • Page 46: Function For Cancelling Erroneous Count

    Function for cancelling erroneous count Function for cancelling erroneous count This function is for canceling erroneous count caused by noise or other fac- tors and indicated by count values that are clearly different from the normal particle count. If such a count occurs during periodic measurement in auto- matic measurement mode, the value is replaced by data from the immediately preceding measurement or the moving average value up to the preceding measurement.
  • Page 47 Function for cancelling erroneous count Processing of erroneous counts If during periodic measurement a given period exhibits an abnormal count, the erroneous count is replaced by the count from the immediately preced- ing measurement. During moving average measurement, the moving aver- age up to the preceding measurement is used to replace the erroneous count measurement value.
  • Page 48 Function for cancelling erroneous count What to do when erroneous count occurs Changes in environmental temperature and other environmental conditions, contamination of particle detector assembly (fl ow cell) and optical system, changes in characteristics due to light source aging or prolonged use and similar factors can lead to an increase in erroneous count frequency.
