Experimental research of balances were carried out by the method of direct measurements with the use means of the measurement technique: the set of mass standards ГЭ -1110, МГО-Іa-1110, autotransformer laboratory LATR-2, with an initial stress from 1 to 250 V; the voltmeter with alternating current F266, thermometer laboratory TL -4. By the results of the experimental research were obtained: a number of the values of absolute error of the loaded balances with the weighing of standard weights with (without) the selection of the container mass; a number of the values of the absolute error with a change in the position of weights on cup of the balances; a number of the values of unloaded balances indications; the experimental mean-square deviation of the results of mass measurements with loading and unloading balances by standard weights; boundary of the confidence interval of balances absolute error random component. The drawings of translucent barrel for protection zone of weighing from the action of air currents are developed. In the case of not conducting the modernization, ВЕТУ 02-01-01-98 can be eliminated, the loss in control over authenticity of transfer the size of the mass unit from the state standard to the working standards of mass of 1a nd to the working weights of the class of the precision Е1 and E2 with the appropriate decrease of the volumes of works on [GMA] and checks of the working standards of the mass of 1a and 1 discharges to the sum from 36,4 to 50,2 thousand grn. every year.
