We want to make sure that our balance is zeroed
If we look closely we currently
See that our balance is not zeroed
To zero our balance we are going
To turn this adjustment *** until
Our arrow lines up with zero
Now that we have all of our riders at the zero mark
And our arrow is at zero
We will proceed to measure our first object
Now that we have zeroed our scale
We are going to place our first object onto the pan
Today our first object we are going to measure
Is a stapler
With our stapler on the pan
We notice our arrow is well above zero
So our first step we need to do
Is move our 100 gram rider
We are going to move our 100 gram rider
Until our arrow falls below zero
We want to make sure that the arrow
On the rider lines up with the number on the scale
We are currently up to 300 grams
And are not below the zero
Once we reach the 500 gram mark
We notice the scale falls below zero
So we need to move the rider one notch back
Now that we have moved the 100 rider
We will move the 10 gram rider
450 grams and it is still above zero
Lets continue to move the 10 gram rider
Now at 480 grams we have fallen below the zero
We need to move our 10 gram rider
One notch back to 70
Now we are just above the zero
Now it is time to move our
Third and final rider the one gram
It is best when moving the one gram rider
To just slightly tap with your finger
Because we want the balance
To be even at the zero
Slight subtle movements are best
To avoid disrupting the accuracy of the scale
As you can see we are just
Slightly below the zero on our scale
So we are going to bump back our one rider
Just a little bit
We now have our balance
Lined up at the zero
Now we need to add up
And total the three riders together
Our 100 gram rider is at the 400 mark
Our 10 gram rider the 70 mark
And our one gram rider is exactly
At 4 grams
If we add the three together
We come up with a total mass of our stapler
Of 474 grams
And that�s how we can accurately
Use a triple beam balance
To measure the mass of an object
