# What is the function of the pointer triple beam balance?

## What is the function of the pointer triple beam balance?

The pointer is present on the right hand side of the triple beam balance. By default, it points to zero on a labeled scale. Together the pointer and the scale are used to ascertain when the beams are at their resting position and when the correct mass of an object has been found.

What are the parts of triple beam balance?

While the designs of various triple beam balance models differ slightly, they have two basic components in common: the base and the pan. The base is a long metal platform which supports the rest of the apparatus. When moving the triple beam balance, place your hands on either side of the base for stability.

### How do you balance the object on the measurement tray?

How do you balance the object on the measurement tray? An object with an unknown mass is placed on the measurement tray. On the other side of a fulcrum, a set of sliding weights, called riders, slide on beams to balance the object.

What does a triple beam balance look like?

The triple beam balance is an instrument used to measure mass very precisely. Such devices typically have a reading error of ±0.05 grams. Its name refers to its three beams, where the middle beam is the largest, the far beam of medium size, and the front beam the smallest.

## What are the steps in using a triple beam balance?

Place the object to be weighed on the center of the pan. Make sure that the scale is not leaning on anything and that the entire object is on the pan. Slide the 100-gram poise to the right right one notch at a time. When the indicator drops below the fixed mark, move the poise to the left one notch.

How do you zero a triple beam balance?

The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero.

### What are the 5 steps to use a triple beam balance?

What are the 5 steps to using a triple beam balance?

1. Step 1: Important Parts. Important parts:
2. Step 2: Setup.
3. Step 3: Zeroing the Scale.
4. Step 4: Specimen Selection.
5. Step 5: Using the 100 Gram Slider.
6. Step 6: Using the Ten Gram Slider.
7. Step 7: Using the 1 Gram Slider.
8. Step 8: Determining Your Mass.

Which rider on the balance should be moved first?

middle
The middle (heaviest) rider should be moved first. This rider measures the largest unit of mass used.

## What’s the zero mark on a triple beam balance?

Zero adjustment knob – This is used to manually adjust the triple beam balance to the ‘zero’ mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero. The zero adjustment knob can be used to adjust the scale pointer. Place the objects on the pan and adjust the riders.

What do the pointers do on a triple beam?

Pointers – The scale pointer marks the equal point of the object’s mass on the scale and mass on the beam Zero adjustment knob – This is used to manually adjust the triple beam balance to the ‘zero’ mark (check to ensure that the pointer is at zero before use).

### Where is the Pan located in a triple beam balance?

The solid metal platform which supports the rest of the parts of the triple beam balance is known as the base. It provides stability to the apparatus while the measurements are being taken. The pan is located on one side of the apparatus and rests on top of the base.

What is the reading scale for triple beam balance?

The reading scale can be enumerated that the middle beam reads in 100 gram increments, the front beam can read from 0 to 10 grams, and the far beam can read in 10 gram increments. The triple beam balance can be used to measure mass directly from the objects, find mass by difference for liquid, and measure out a substance.
