6. The top scale measures hundredths (.01) of grams When the zero mark is between tenth marks on the dial, you then read the hundredths scale. Which mark on the hundredths scale Makes the best straight line with a mark on the dial?

7. You must look straight on at the dial to match lines correctly. These two marks seem joined the best to make a straight line. Count from the zero line on the top scale to find how many hundredths.01.02.03.04.05.06 This scale shows:.06 g

8. Add all the values together for the mass..06.7 4 4.76 This dial shows: 4.76 g

9. That’s it! Now you can read a Dial-a-Gram Balance! Oh wait -- don’t forget to add any riders you moved. hundreds tens (this is set at 50 g) Back to the beginning Back to home page
