A decimal balance uses the lever in which the arm for weights is 10 times longer than the arm for weighted objects, so that much lighter weights may be used to weigh heavy object. [11] Similarly a centesimal balance uses arms in ratio 1:100. For a simple pan balance to be in equilibrium, the fulcrum must be offset from the lever arm.
Beams - The three beams on the balance are used to set the level of precision, with each beam working at different increments (1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is recommended that one start with the lowest level of precision (e.g 100 gram increments).

When using the triple beam balance, it is recommended to start with the lowest level of precision (e.g. 100 gram increments) and then work your way down.
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. A 19th-century steelyard crane
A Roberval balance made by W & T Avery Ltd. in England Detail: the bottom horizontal beam is hidden under the protective cover A Roberval balance shown responding to two masses of equal weight. The Roberval balance is a weighing scale presented to the French Academy of Sciences by the French mathematician Gilles Personne de Roberval in 1669.
The tolerance for specific temperatures depends on the person and what they are used to. My best advice is to stay within your comfort zone. If you are doing something that you haven’t done ...
