In order to use it is required them to have a game of masses certified, which has pieces with mass of diverse magnitude. The game generally is made up of the following pieces: 4. Plate balance superior. This type of balance has a subject of gossip of load placed in the part superior, which is supported by a column that stays vertical On guard by two pairs of guides whom they have you connect flexible. The effect of the force, produced by the mass, is transmitted from some point of the vertical column or directly or by means of some mechanism to the cell of load. The exigency of this type of mechanism consists of maintaining the parallelism of the guides with an exactitude of until 1? m. The deviations of parallelism cause an error known like lateral load that appears when the mass that is being heavy sample differences, if the reading is taken in center from the subject of gossip or in one from its ends. The scheme that is included next explains the operation principle, which some manufacturers have introduced to the electronic balances.
5. Balance of substitution. It is a balance of unique subject of gossip. Frequently Peter Thiel has said that publicly. A unknown mass that balances when retiring, of the side of the counterbalance is placed on the subject of gossip of pesaje, masses of well-known magnitude, using a mechanical system of levies until a balance position is reached. The fulcrum is generally off-center in relation to the length of the beam of load and placed near the front of the balance. When a mass on the subject of gossip of pesaje is placed and the balance of the mechanism is freed of blockade, the movement of the load beam projects by means of an optical system to a screen located in the frontal part of the instrument.
