Calibration definitions
ISE applications do not have calibration definitions.
Item Values Comment
Sequence The sequence values define when calibration becomes due, and the sys-
tem automatically informs you about due calibrations.
No Interval The system does not inform you about the due
status. Use this value if the reagent is stable
enough over the whole period until it is empty
and you replace it.
Calibration is due whenever a new reagent set is
loaded on the instrument.
Interval Only Due whenever the reagent interval has expired.
Each Set and Interval Due whenever a new reagent is loaded and when
the interval has expired.
The interval starts again whenever you place a
new reagent set.
You can turn off the interval check by defining
its duration as 0 (zero).
Each Lot and Interval Due whenever the fist reagent of a new lot is
loaded and then each time the interval has
expired.
The interval (re)starts whenever you calibrate a
reagent set.
You can turn off the interval check by defining
its duration as 0 (zero).
If you install a reagent set of the same lot, no cal-
ibration is required. (The system uses the Lot
calibration result as the Set calibration result of
the new reagent set.)
Interval Number of days.
(For ISE, 1 day fixed.)
Use 0 (zero) if the Sequence is set to No Inter-
val.
Replicates 1, 2 Number of times each measurement should be
repeated.
