 CALIBRATING LaMOTTE PRE-PROGRAMMED TESTS
The LaMotte Pre-Programmed Tests have been pre-calibrated. Recalibration of
the pre-programmed tests by the user is not possible. However, a procedure
to standardize the calibration can be performed to obtain the most accurate
readings or to meet regulatory requirements.
The LaMotte Pre-Programmed tests are standardized with one standard
solution. To standardize over the full range of the test, the concentration of
the standard should be chosen from the high end of the range. Alternatively, if
samples do not cover the full range of the test, a standard should be chosen
that is close to the concentration of the samples.
The standardization procedure should be followed as often as required by
regulations and laws for compliance monitoring.
In the example below, the Aluminum calibration will be standardized.
Prepare a standard solution to be tested. In this example, 0.30 ppm aluminum.
