What is the difference between Weight & Mass?
Weight is often taken to mean the same as mass, however, there is a difference, which for calibration purposes is important to note:
Mass is the measurement of the amount of material that makes up the object. Weight is the gravitational force acting on the object.
Why Calibrate?
Accuracy is key as weights are used to calibrate scales and other weighing equipment, an inaccurate weight, in turn, will have a knock-on effect and will produce inaccurate scale calibration. A calibrated set of weights allow the scale error of the balance to be assessed and corrected to the highest accuracy.
Calibration weights are available in a wide range of classes and specifically used for certain types of balances such as:
- M1 calibration weights are used for testing and calibrating standard scales
- F1 calibration weights are used for testing and calibrating precision electronic balances
- E2 calibration weights are used for testing and calibrating analytical balances
How is it Calibrated?
Calibrating weights must be done with the greatest of care an precision, weights must not be:
- Touched with bare hands
- Handled with sharp or abrasive tools
- Come into contact with contaminated or unclean surfaces
- Slid or rolled across surfaces
- Knocked over or into each other
- Cleaned using non-recommended solvents or materials
These factors can all affect the integrity of the weight and result in inaccurate readings, therefore, appropriate care and tools must be used in the calibration process. WAGA ensure to handle your weights with care to assure accuracy at all times throughout calibration. There are multiple methods of weighing techniques in mass metrology and depending on the desired accuracy depends on which method is used, methods include:
- Direct reading measurements
- Weighing by differences
- Substitution weighing
- ABA calibration
- ABBA calibration
- Cyclic weighing
- Weighing by sub-division
Types of Weight & Mass Equipment?
