When using the triple beam balance, it is recommended that one start with the lowest level of precision (e.g 100 gram increments). For example, if an object weighs 327 grams, the 100 gram pointer will drop below the fixed mark on the 4th notch (400g); it will then need to be moved back to the third notch (300g).
Before using a triple beam balance, the scale pointer should be at zero. [6] The zero adjustment knob can be used to adjust the scale pointer. Place the objects on the pan and adjust the riders until the scale pointer is at zero again, and then sum the weights marked (e.g. the 4th notch of 100 gram beam is 400g) to find the weight of the sample.
The balance (also balance scale, beam balance and laboratory balance) was the first mass measuring instrument invented. [1] In its traditional form, it consists of a pivoted horizontal lever with arms of equal length – the beam or tron – and a weighing pan [10] suspended from each arm (hence the plural name "scales " for a weighing instrument).
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.
