Special Calculations Definition
Introduction
The two types of Special Calculations that can be reported with a sample are:
• Predefined by Beckman Coulter
• Operator defined
There are 15 predefined special calculations, which may be enabled/disabled by the
operator. These special calculations cannot be modified or deleted from the system.
There are 25 additional special calculations, which may be defined, edited or deleted
by the operator.
When a special calculation is enabled, the value is reported only if the appropriate
chemistries for the equation are programmed and run for a given sample ID.
From the Setup screen, select <12> Special Calculation to define, edit, delete or view
a special calculation.
Special Calculations may be viewed at any time.
The system must be in Standby or Stopped to define, edit or delete operator-defined
Special Calculations or to enable/disable them.
The default for any Special Calculation is disabled.
