More Information
Summary:The embodiment of the invention provides a sample analyzer which comprises a liquid suction assembly, a driving assembly and a signal acquisition and analysis assembly, and the signal acquisition and analysis assembly is used for converting capacitance change on the liquid suction assembly into an electric signal; in the process that the driving assembly drives the liquid suction assembly to move downwards towards the container, the signal collecting and analyzing assembly collects and analyzes the electric signals, and when the electric signals meet the preset threshold value condition and do not return to the preset range near the signal base line, liquid level in-place information is sent. After the electric signal meets the preset threshold condition, whether the electric signal returns to the preset range near the signal base line or not is continuously judged to recognize whether the electric signal is electrostatic interference or the real liquid level, so that the accuracy of liquid level detection of
