ACCESSORIES PRINCIPLE OF OPERATION The color of every object we see is determined by a process of absorption and emission of the electromagnetic radiation (light) of its molecules. Colorimetric analysis is based on the principle that specific compounds react with others and form a color, the intensity of which is proportional to the concentration of the substance to be measured.

DISPLAY CODE GUIDE This indicates that the meter is in a ready state and zeroing can be performed. Sampling in Progress. This prompt appears each time the meter is performing a measurement. This indicates that the meter has been zeroed and measurement can be performed. A zero reading was not taken. Insert a sample before adding reagent and press ZERO. Under range. A blinking "0.00" indicates that the sample has absorbed less light than the zero reference.
• Let the sample stand and the flocculant agent will start to settle. • After approximately 2 minutes and when the upper half of the bottle becomes limpid, add 10 drops of HI 93732C. • Replace the cap and swirl the solution. The sample is ready for measurement when it is yellow and completely limpid. • Fill the cuvet up to 1.5 cm (¾”) below the rim with 10 mL of the unreacted (original) sample, and replace the cap. This is the blank.
