• An uninterruptible calibration
A yellow dialogue box does not contain a STAT button next to the
countdown clock. During the initialization period there are several
uninterruptible calibrations mentioned in Cartridge Initialization (Init).
Uninterruptible calibrations are also encountered when a scheduled
calibration is postponed for 15 minutes. The user can typically
postpone a scheduled calibration by running samples when a
calibration is pending, or by interrupting the calibration (pushing the
STAT button) for up to 15 minutes.
Cartridge Initialization (Init)
When a new cartridge is installed the system must initialize the cartridge
and verify the performance of the sensors. In order to properly check the
electronics, fluidics, and performance of the sensors, the cartridge must go
through a 22 minute initialization (init).
When a new cartridge is placed correctly on the Rapidpoint 400 series
system, the system performs an electronic check, initializes the luer valve
on the cartridge, and primes the reagents. This is followed by a series of
calibrations to wet and establish the sensors’ performance.
The system is ready for its first sample analysis 22 minutes after the
cartridge is placed on the Rapidpoint 400 series system. Samples run at
this point are in retrocal mode. Twenty minutes after the init completes, the
system performs an uninterruptible 2-point calibration. After this
uninterruptible 2-point calibration is performed, a 1-point calibration is
scheduled 20 minutes later. If a sample is run before the 20 minute time
expires for this 1-point calibration during the initialization period, the
retrospective calibration with the sample replaces the scheduled 1-point
calibration and a new 20 minute timer begins.
