Accuracy
-
These terms are often used interchangeably to indicate how well a scale displays the correct results. Accuracy is the ability to display a value that matches the
ideal value for a known weight.
-
Animal / dynamic weighing
-
It is difficult to accurately weigh living animals such as a rabbit, which may move around during weighing. The movement will not allow the display of the balance to
show a stable weight and hence the true weight of the animal can not be determined. To overcome this problem, the balances can be designed to offer animal / dynamic weighing mode. The balance
works out an average weight based on the force exerted by the animal over an extended period of time. Once the internal calculation is completed by the balance, it will hold the value.

Balance
-
A weighing machine. The terms scale and balance are often used interchangeably. Historically a balance was a device that determined mass by balancing an unknown mass
against a known mass as with a 2 pan assay balance. In modern weighing machines balances are usually of the design that uses a force restoration mechanism to create a force to balance the force
due to the unknown mass.

Density Determination
-
Using a balance to determine the density of material, either solids or liquids. (Density is the grams/cubic centimetre). If a solid material is used it is weighed
in the air and when suspended in a liquid. The density can be determined either manually or in some balances by using special software. To determine the density of a liquid a special float of
known volume is weighed in air and in the liquid.

IP65 Wash down rated
-
The IP rating (international protection rating) is defined in international standards IEC 60529 and is a rating for the protection from outside objects like dust
and water. IP 65 means that it is dust tight and protected from low pressure water jets. In basic terms it means that the scale or balance is wash down or can be used in a wet
environment.

Levelling
-
The procedure to set the balance so the platform is horizontal. This gives the balance a position that is repeatable so the results will be the same if the balance
is moved. This is done using levelling feet.
-
Linearity
-
The ability of a scale or balance to show the correct value throughout the weighing range. Usually tested by placing known weights on the balance from near zero to
full capacity.

Mass is a physical property of a material. The mass gives a material weight when gravity pulls the material toward earth. The units of mass are gram and kilogram.
The terms mass and weight are often used interchangeably.

To set a display to show zero weight. This is used to remove the weight of any packing or containers so that only the weight of the material within the container is
shown. The Tare value is deleted from the remaining weight that can be added to a scale. For example if a scale has capacity of 500g and then 200g is tared, the remaining capacity is 300g. Often
Zero is used interchangeably.

Newtons, etc.
-
Weight
-
The weight of a object is the result of gravity pulling a mass toward earth. When a balance has been calibrated using a known mass then any unknown mass placed upon
the scale will have a weight proportional to the known mass. The units gram and kilogram are often used to describe the weight of on object. It is common for mass and weight to be used
interchangeably. A weight can also be any mass that is used, for example to put a weight on the scale.

Zero
-
To set the display to show zero weight. Used to reset the zero condition of a scale when small amounts of material are on the platform. Zero does not take away from
the capacity of a scale. However it will only work in a very small range around the original zero condition for the scale. Zero and Tare are often combined on one key, the terms are often used
interchangeably.
