     SAMPLE DILUTION TECHNIQUES & VOLUMETRIC MEASUREMENTS If a test result using the SMART3 Colorimeter gives an over range message then the the sample must be diluted. The test should be repeated on the diluted sample to obtain a reading which is in the concentration range for the test.

  • Page 19: Interferences

     INTERFERENCES LaMotte reagent systems are designed to minimize most common interferences. Each individual test instruction discusses interferences unique to that test. Be aware of possible interferences in the water being tested. The reagent systems also contain buffers to adjust the water sample to the ideal pH for the reaction.

    GENERAL OPERATING PROCEDURES The operation of the SMART3 Colorimeter is controlled by a microprocessor. The microprocessor is programmed with menu driven software. A menu is a list of choices. This allows a selection of various tasks for the colorimeter to perform, such as, scan blank, scan sample, and edit test sequences. The keypad is used to make menu selections which are viewed in the display.
