Any weight measurements are subject to error which must be minimized to ensure the lowest possible systematic quantitative deviation in the final result obtained. It is important that prior to carrying out any weighing task you are familiar with any governing bodies to whose standards you must comply or with any in-house SOPs for your company regarding the correct use of balances.
