Exit Check Criteria
Introduction
When preparing to save a chemistry protocol after editing, the parameters are checked
for correctness, completeness, and consistency. Chemistry protocols that fail any Exit
Check criteria are not allowed to run. The following requirements specify the Exit
Check criteria and parameters presented for modification when the user elects to
correct detected protocol errors.
Wavelengths
• The primary wavelength must not be None.
• The secondary wavelength must not be None.
• The primary wavelength must be different from the secondary wavelength.
Calibration
• The calibration time limit must be greater than zero hours if the number of calibrator
levels is greater than zero.
• The sequence of calibrators must be in ascending target value order.
• Calibrator target values must be unique -- no two calibrator levels can have the same
analyte target value (setpoint).
• Models 1, 2, 3, 8 & 9 and DAT do not support negative setpoints.
• If the math model is either Model 1 or Model 9, the number of calibrators must be
five or six levels only.
• If the math model is Model 2, Model 3, or Model 8, the number of calibrators must
be exactly six levels.
• If the math model is DAT, the number of calibrators must be exactly three levels.
The middle level defines the cutoff between positive and negative. The lowest and
highest levels are used to measure the reagent sensitivity.
• If the math model has been specified as LINEAR, the number of cal levels must be
0, 1 or 2.
• If the math model is DAT, the result units must be mA/min (rate) and mA
(absorbance).
Blanking
• The reagent blank end time must exceed the reagent blank start time by a minimum
of one processing cycle.
• The blank absorbance high limit must be greater than the blank absorbance low
limit.
• The rate low limit cannot exceed the high limit for positive reaction direction
chemistries.
• The rate low limit must exceed the high limit for negative reaction direction
chemistries.
