Precautions for the use of Triple beam balance

The Triple beam balance is so named because it has three horizontal bars with scales. The Triple beam balance has three sets of riding yards but no weights. First, use the riding scale with the largest scale. If the pointer does not return to zero, adjust the riding scale with the smaller scale. A Triple beam balance has three horizontal bars, each of which has weights of different masses placed on it. By moving the position of the weights, you can adjust the resistance to the opposite side of the object with the fulcrum of the balance as the center. The object to be tested is placed in the weighing paper or the weighing pan and then placed on the weighing pan of the balance.

Since the crossbar of a Triple beam balance is supported on the top edge of a wedge-shaped column with a very sharp top, the object to be measured should be placed lightly when using the balance, so as not to damage the fulcrum due to inadvertent impact and affect the accuracy of measurement. Most balances need to turn a wrench on it when not in use. After turning it, the crossbar can be lifted up and the wedge-shaped support can be separated and locked to ensure the safety of the balance. When using, you should first turn the wrench back to the normal use position.
