Steps

  1. Open the ffem Collect app, and select "Fill Blank Form". Select the form you need to fill out.
                    
  1. Answer all the questions in the form, swiping left to go to the next questions. When you reach the water quality questions, launch the test for Aluminum
                    
  1. Rinse the empty cuvette and measuring tube twice with the sample to remove any traces of previous solutions. Measure 10 ml of the sample with the measuring tube.

             

  1. Add 1 vial of Aluminum reagent A, followed by aluminum reagent B and then Aluminum Reagent C to the measured solution. Close the lid of the measuring tube and shake it to ensure proper mixing of the reagent and sample.
                
  1. Pour the contents of the mixing tube into the provided cuvette. Close the lid and fit the cuvette into the pipe.

                                        

  1. Launch the test on the app selecting "No Dilution" on the next screen.
                    
  1. Place the phone face down, and use the sticker to help center the cuvette over the camera. Wait for 5 minutes for the test to complete - you will hear 6 beeps and a "Test Completion" sound.
                                        
  1. You should receive a contaminant concentration value in ppm. Tap Accept Result to return to the survey.
                   
  1. Empty the contents of the cuvette and rinse it once.
