Testing of Electronic Balances,ght of the display represents the smallest value of mass, which the balance is capable to read. In other words, mass of any body placed on it is the integral multiple of mass value of unit digit at the extreme right of the display. Normally it is thought that the balance may best repeat within ± one

Air Density and Buoyancy Correction,re proportional to the product of the respective volumes of the two weights and air density at the time of comparison. Weights of same nominal value have different volumes if their density is not equal. Volume of a stainless steel 1-kg weight differs from that of the platinum iridium mass standard b
