How to Read Anti Freeze (Coolant) BULB TESTER ?

The first ball is your halo meter, the second ball (purple) is the level, the third ball is the concentration, the 4th ball is the volume, and the 5th ball is the weight. Take the readings off of the 1st and 3rd , and use the 4th ball as the unknown coefficient, and find the double integral of the 1st and 3rd , use the result as the unknown in the 2nd and 5th which you'll multiply them together, and divide your result into the integration you did on the 1st and 3rd . This will tell you the normal floating range of each ball and thus tell you if you need more antifreeze or not.
