Variables
An IMMAGE 800 variable is a placeholder which may represent more than one
number. A maximum of six variables may be defined for use in Custom Calculations.
The numeric value for a variable is assigned during sample programming and that
value will be used for the Custom Calculation on that particular sample. (Refer to
CHAPTER 7,
Sample Programming
Defining and Editing Variables
The instrument status must be in
Standby
in order to proceed with the steps below to
define or edit variables.
Custom Calculations
• A Custom Calculation name must be unique with a maximum of 15 characters.
• Calculation formulas are not affected if the operator deletes the chemistries from the
Chemistry Configuration.
• The operator must enable or disable each Custom Calculation individually.
• If the sample type defined for a calculation is serum, the calculation is applied to
samples with a sample type of serum or plasma. If the sample type defined for a
calculation is plasma, the calculation is applied to samples with a sample type of
serum or plasma.
• Custom Calculations that require two samples must be linked through Sample ID.
Each sample can only be linked to one other sample. (Refer to CHAPTER 7,
Sample Programming
• Slope-offset adjustments (if used) will be applied to the chemistry result before the
calculation is performed.
• Custom calculation results are reported without units.
