Introduction Wrong or inaccurate measurements can lead to wrong decisions‚ which can have serious consequences‚ costing money and even lives. The human and financial consequences of wrong decisions based on poor measurement being taken in matters as important as environmental change and pollution are almost incalculable. It is important therefore to have reliable and accurate measurements which are agreed and accepted by the relevant authorities worldwide. Metrologists are therefore continuously

They are also used for work holding and inspection on the shop floor. In some shop work holding applications‚ the accuracy would not need to be to the level of lab or inspection gage blocks. V-blocks are precisely square‚ and the V-groove should be in the exact center of the block. The prime purpose of a V-block is to

Chapter 13 AC MEASUREMENT This chapter explains rectification for measurement and rectifying instruments. Knowledge of the circuit principles will help you use these instruments properly and measurements alternating current correctly. One of the most common and economical methods for measuring alternating currents is to rectify these currents and read the resultant DC on an analog or digital volt-ohm meter (VOM). You need to take many considerations into account when using rectification: what

The accuracy of the measurement the volumes is the degree of closeness of measurements of a quantity’s actual volumes while the precision of the volumes is the degree to which repeated measurements under unchanged conditions show the same results. Each of volumetric glassware is marked with its total volume‚ the notation of TD for ‘to deliver’ and TC for ‘to contain’ and also with the temperature at which the calibration applies. For greatest accuracy‚ volumetric glassware
