Weighing scales, weighing instruments, weighing balances… different resources are using different terminology. 0000032169 00000 n Instrument that indicates the price to pay by means of price charts or scales related to a range of unit prices. 0000020302 00000 n ± 0.05 cm3 • burettes are read twice, so the overall maximum error is 2 x 0.05 = ± 0.1 cm3 0000032529 00000 n permissible tolerance limits for a 200-g class E2 calibration weight, the readout may differ from the actual weight by up to ±0.30 mg. 0000000016 00000 n %PDF-1.6 %���� Weight is the force applied by a Mass when gravity is acting upon it and this is the force measured by a weighing scale or balance but Weight is the commonly used term, so we use it throughout this guide. 0000026600 00000 n The tolerance is the prescribed limit of - how far out from the prescribed weight it is allowed to be. 0000031834 00000 n Or, your scale may be on an uneven surface or on carpet. h�bbd``b`�$� �S@B�1�`�$b��2Hb��c �n�p�t`�Ab� ��*���ҁ�`���@�� �r�g��) � They allow the scale inspector or technician to load the weights required for the test into the weight cart and then move it to various positions on the scale deck, with a single handling of the weights. (i) Parallax The distance between the dial and the index shall not exceed the width of the scale spacing, without exceeding 2 mm. 5 Tolerances (Maximum Permissible Errors) ... and distributors of scales, load cells, and other weighing devices may find these specifications and tolerances useful. If you use your scale for commercial purposes, you need legal-for-trade calibration. 0000011061 00000 n The range is shown in graduations, where the minimum value of the displayed graduation is the ‘least count’ or ‘resolution’ of the instrument. Physical characteristics shall be based on construction, design, surface area, materials, magnetism, density, surface finish, weight adjustment, and marking. In addition, for the purposes of this Recommendation, the following definitions apply. 0000016221 00000 n Update February 2019: We made an educational video on weighing scale calibration, you can find that in this link: Weighing Scale Calibration Video . 0000054213 00000 n Intended for use in normal commercial transactions where goods are sold by weight. 0000022239 00000 n 0000013884 00000 n The scale marks on an indicating device shall be straight lines of uniform thickness, uniformly spaced. 0000002003 00000 n 0000003320 00000 n 0000050317 00000 n These errors are doubled for multichannel pipettes. 0000001708 00000 n Readability of the Scales; All weighing instruments have a calibrated range known as the ‘span’ that has a minimum and maximum limit. The height of a plant is 45 cm with an estimated absolute error of 0.9 cm what percent is the relative error? As an example, scales with a maximum range to 3000g and a readability of 0.01g, may only become accurate at around 0.2g; whereas scales with a range to only 600g may become similarly accurate at about 0.10g. ... • the maximum permissible errors (MPE) on verification; and • the maximum permissible errors (MPES) in service. The maximum permissible error from nominal value at 1 kg is ±160 mg.
