PURPOSE:To prevent the maloperation of a particle analyzer by constituting it so that the conditions for the statistical operation are inputted by moving the cursor on the display while observing visually. CONSTITUTION:The particle analyzer comprises a particle detector 1, a comparing circuit 2, a signal generating circuit 3 which generates the signal representing the size of particles, an operational controller circuit 4, a read-only memory 5, read/ write memories 6, 7 and 8, an input means 9, a display means 10 and a recorder 11. The input means 9 is provided with push-button switches 14-17 to make a cursor move onto the display on the display means 10 and perform the position display of said cursor. Accordingly, moving the cursor permits the conditions for various operations to be inputted. |
