3-2 Rapidlab 1200 Operator’s Guide: Calibration
02087462 Rev. V
The system performs the following calibrations after some maintenance procedures:
Calibration
Type Frequency Description
2-Point During accelerated calibration
intervals, which occur after you
perform sensor maintenance.
You can manually initiate this
calibration.
Measures 2 reagents of known
concentration to adjust either the
offset or the slope drift for the
following parameters: pH, pCO
2
,
pO
2
, Na
+
, Ca
++
, K
+
, Cl¯, Glu, and
Lac.
Rapidlab 1245 and 1265 systems:
measures 2 reagents of known
concentration to adjust the offset
and the slope for tHb and CO-ox
fractions.
1-Point Plus Rapidlab 1245 and 1265 systems:
after you replace the CO-ox
sample chamber.
Measures 1 reagent of known
concentration to adjust either the
offset or the slope for the
following parameters: pH, pCO

Measures 2 reagents of known
concentration to adjust the offset
and the slope for tHb and CO-ox
fractions.
Accelerated
Calibration
Intervals
The system starts accelerated
calibration intervals in 2 instances
after you open and close the
measurement module door:
If you answer the question “Did
you remove or replace any
sensors?” with Yes, or if you
answer with No and the system
detects a drop in pressure in the
sample path. The system only
detects a drop in pressure if you
followed the procedure Replacing
the Sensors‚ page 5-29.
The system performs a 2-point
calibration every 2 hours for the
first 8 hours of the accelerated
calibration interval.
