Initialization Calibration Timeline
After calibration number 12 the system performs a 1-point calibration every
30 minutes with every fourth calibration a 2-point calibration, until the end
of the initialization and retrospective calibration (retrocal) period. All
calibrations after calibration number 12 are interruptible.
The initialization and retrospective calibration (retrocal) periods are not
complete until either 7.5 hours has passed or all of the following are true:
• two scheduled calibrations occurred after calibration number 12
• both calibrations passed the first time without a repeat
• no samples were run between the two scheduled calibrations
When the initialization and respective calibration (retrocal) are complete,
the scheduled calibration timeline of 1-point calibrations every 30 minutes,
2-point calibrations every 2 hours, and a full 2-point calibration every
8 hours begins.
NOTE:
On Rapidpoint 405 systems, all 2-point calibrations are replaced by
full calibrations for the first 24 hours.
