EDIT USER TESTS
If a test other than the LaMotte programmed tests is performed regularly, a
calibration for it may be entered in one of the 10 User Tests. These tests are
originally named “User Test 1 - 10". It will be possible to rename the test,
select a wavelength, enter a new calibration, select the number of decimal
places used to display the results, and select the units. 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 the ability to handle 2 data points. The colorimeter will
determine the absorbance of the standards and calculate a response that will be
stored to determine the concentration of future samples of unknown
concentration. These standards should cover all the concentrations for the
range of the test being performed and be scanned beginning with the low
concentration and finishing with the high concentration (for more
information, see CALIBRATION CURVES, p. 13). Prepare these solutions
prior to entering a new calibration.
NOTE: A calibration procedure must be performed before using any of the
User Tests.
The User Tests can be placed in any of the alterable sequences using EDIT
