5 Main function
a)Sample Adding Method : Insert the sample any time; detect the sample any time;
b)The output of the results:Display and print samples' No. (serial number), Wechsler results and the whole process of erythrocyte sedimentation rate curve, detection time and temperature; when the instrument detection time is 60 minutes, it can automatically calculate, display and print Katz index;
c)Instrument can choose the ambient temperature compensation. When selecting the function, when the room temperature is 18 ℃ -30 ℃, it amends to 18 ℃ according to the blood sedimentation calibration test results. (It can be selected in accordance with laboratory, the default of equipment is no compensated);
d)Equipment can be stored not less than 150 samples of the test results, including the sample number (serial number), erythrocyte sedimentation rate values and the dynamic curve;
e)There are power-off protection function, when a sudden power failure, automatic detection has been completed the tested results.
f)Built-in thermal printer preparation equipment, it has automatic, manual printing options.
g)Operation interface: Film keyboard operation;
h)Communication Interface: RS-232 serial interface;
