Calibration
The analyzer contains software which permits one of six parameter configurations: Na
+
/K
+
/Ca
++
,
Na

/K

/Cl
-
, Na
+
/K
+
/Li
+
, Na
+
/K
+
, Na
+
/Li
+
, Li
+
. Each of these configurations uses the same calibration
solutions.
A 2-point calibration is performed automatically every 4 hours in READY mode and a 1-point calibra-
tion is automatically performed with every measurement.
An automatic calibration procedure is also performed shortly after power-on or reset. A calibration
cycle can also be initiated manually at times when no sample measurements are performed.
Quality Control
AVL recommends that at least once daily or in accordance with local regulations, quality control
solutions with known Na
+
, K
+
, Cl
-
, Ca
++
and Li
+
values should be analyzed at two levels (normal and
low or high). For further details, please review the Quality Control section of the Operator's Manual.
Results obtained should fall within limits defined by the day-to-day variability of the system as mea-
sured in the users laboratory. If the results fall outside the laboratorys acceptable limits, refer to the
Troubleshooting Section of the Operator's Manual.
