HOW TO USE A TRIPLE BEAM BALANCE
 Triple beam
balance is used in both physics and chemistry practical in schools. Science
students must ensure that they have proper knowledge on how to use a triple
balance in the lab. The triple balance is used by science students for taking accurate
mass measurement of a given sample, usually calibrated in grams.

been measured accurately. The triple balance functions with three counter weights
attached to the scale. This is to accurately find the weight of any
object.
You must have been
familiar with a balance. 
A balance is usually recommended for chemistry and
physics courses, frequently to be used for weighing out small amounts of
chemicals to use in solutions. To get you started on easy and efficient use of
your triple beam balance, here are a few suggestions.

Before you weigh something, ‘zero‘ the balance. Do these
by sliding back all the weight poises (that slide along the beams) so that the
pointer is right at the zero line. You might need to turn the zero adjustment
knob a little bit to get it right at the line.

zero' the balance.

 When you set an object on the
balance platform, the pointer immediately goes up and is no longer zeroed. To
find out the weight of the object, you’ll need to slide the weight poises until
the pointer is at zero again. Start with the two heavier weight poises and then
use the lightest one to do the fine tuning.

To read the weight of an object in grams, add up
the number that each weight poise is at when the pointer zeroes. For example,
if the heaviest poise is at 100 g, the next one at 30 g, and the lightest one
at 5.4 g, then the total weight of the object is 135.4 grams.
