Pointers - The scale pointer marks the equal point of the object's mass on the scale and mass on the beam; Zero adjustment knob - This is used to manually adjust the triple beam balance to the 'zero' mark (check to ensure that the pointer is at zero before use). Before using triple beam balance, the scale pointer should be at zero.

A Material Handler Scale can also transfer the weighing information to a cloud service or an ERP system for real-time monitoring and management of material flow. A pallet jack scale is a device that combines a pallet jack and a weighing scale. It allows you to weigh and move pallets at the same time, saving time and labor.
If the instrument has a needle which points to a scale graduated in steps of 0.1 units, then depending on the design of the instrument it is usually possible to estimate tenths between the successive marks on the scale, so it should be possible to read off the result to an accuracy of about 0.01 units.
The dieter's problem: this scale can only resolve weight changes of 0.2 lbs, even though the digital display looks as if it could show 0.1. In the science of measurement, the least count of a measuring instrument is the smallest value in the measured quantity that can be resolved on the instrument's scale. [1]
A pair of scales: An instrument for measuring mass in a force field by balancing forces. Balance; Check weigher measures precise weight of items in a conveyor line, rejecting underweight or overweight objects. Inertial balance; Katharometer; Mass spectrometers measure the mass-to-charge ratio, not the mass, of ionised particles. Weighing scale

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.
