EDIT USER TESTS
If a test other than the standard LaMotte tests stored in the colorimeter is
perfomed regualrly, a calibration may be entered in one of the 25 USER
TESTS. These tests are originally named “USER TEST 1 - 25".
It will be possible to rename the test, select a filter, enter a new
calibration and select the number of decimal places used to display the
results. A USER TEST may be added for a reagent system for which no
precalibrated test exists. A calibration of a LaMotte reagent system may
also be entered. The calibration of a USER TEST can be changed at any
time.
The USER TESTS have a two point calibration. This requires that the
test have a linear calibration, if accurate results are expected. The
colorimeter will determine the Absorbance of two standards and
calculate a response that will be stored to determine the concentration of
future samples of unknown concentration. One of these standards should
represent a low concentration and one should represent a high
concentration for the range of the test being performed (for more
information about this, see CALIBRATION CURVES, page 10). Prepare
these solutions prior to entering a new calibration.
NOTE: A calibration procedure must be performed before using any of
the USER TESTS for actual test samples if meaningful results are to be
obtained.
The USER TESTS can be placed in any of the alterable sequences using
the EDIT SEQUENCES mode, as explained for the LaMotte Tests.
