Here ya go:
1) Add with the 5 mL syringe 3 mL of water in the test vial. For a lower resoulution and more tests per kit add 1.5 mL instead of 3 mL.
2) add 6 drops of Ca-1 to the warer in the test vial and swirl gently for 10 seconds. For low resolution 3 instead of 6 drops.
3) Add 1 spoon of Ca-2 (low resoultion approx. 1/2 spoon) and swirl for 5 seconds.
4) Put the plastic tip firmly on the 1 mL syringe and draw into the syringe Ca-3.
5) Add dropwise with the 1 mL syringe the Ca-3 reagent to the water in the test tube. Swirl after each drop a second or two. Continue until the color changes from pink-red to a clear blue color.
6) Hold the syringe with the tip facing upward and read the position of the, now the upper end, of the black part of the piston. ppm Cal = (1 - reading in step 6) x 500
If you chose lower resoulution multiply the calculated result by 2.
