Abstract
In a hematology parameter measuring apparatus, signals indicative of measured parameters are obtained and loaded into first digital registers. Calculated parameter values are generated through use of the values stored in the digital registers. A first parameter value is circulated from a register into a digital divider through a digital data line to set a divisor in the divider. A control circuit circulates a value from another register to the divider for utilization as a signal indicative of a dividend. The output of the divider is coupled to a result register to store a value indicative of the calculated parameter. In this manner, calculated parameter values are obtained, and the first registers retain values indicative of the measured parameter values. The control means may selectively couple signals to a display from any of the registers or to a printing unit.
