Study Notes
Tare Function
- Pressing the tare button on a balance resets the display to zero when a load is already on it.
- This function is essential for obtaining the net weight of a sample in a container.
- The procedure involves measuring the weight of the empty container first, pressing the tare button, and then adding the filled container back to the balance.
- The final reading indicates the net weight of the contents without the container's weight.
Balance vs. Scale
- The terms "balance" and "weighing scale" are often used interchangeably in of mass measurement.
- Scales are typically designed for larger masses (e.g., baby scales), while balances are used for more precise measurements in laboratory settings.
Types of Balances
- Two main types of balances are used in laboratories: precision balances and analytical balances.
- Precision balances are less accurate compared to analytical balances.
- Analytical balances offer higher accuracy and are generally more expensive.
