(11) before the daily work, enzyme cleaning should be carried out. Through the [auto-clean] program, the enzyme washing liquid should be inhaled for automatic enzyme cleaning to ensure the smooth flow of all pipelines. This process is very important for the normal operation of the hematology analyzer. 

(12) during the work of the hematology analyzer, the operator shall closely observe the counting time of white blood cells and red blood cells. If the counting time on one or both sides is prolonged, it indicates that there are precipitated denaturalized proteins in the pipe, and incomplete hole blocking occurs, then press the [Clear orifice] key to wash them in time, and enzyme cleaning is required if necessary.

Through the above measures, it can effectively prevent the appearance of hematocrit analyzer, ensure the normal work of hematocrit analyzer, and ensure the accuracy of test results.
