Section 100 in The Legal Metrology (General) Rules, 2011
100. x dt for class 2 instruments.
Example : maximum capacity = 1000 kgminimum capacity = 200 kgtotalization scale interval = 0.2 kg (see paragraph 2.4)accuracy class of instrument = 0.5∑min 400 x 0.2 = 80 kgBut to satisfy the second indent above:∑min ≥ min = 200 kgTherefore, in this example the minimum value of the minimum totalized load is 200kg.(The values used in this example are not intended to be typical.)(6)Agreement between indicating and printing devicesFor the same load, the difference between the weighing results provided by any two devices having the same scale interval shall be as follows :-(a)zero for digital indicating or printing devices;(b)not greater than the absolute value of the maximum permissible error for automatic weighing for analogue devices,(7)Influence quantities(i)Static temperatureInstruments shall comply with the appropriate metrological and technical requirements at temperatures from - 10°C to + 45°CFor special applications, however, the limits of the temperature range may differ from the above provided that this range is not less than 30°C and is specified in the descriptive markings.Instruments shall be tested in accordance with the static temperatures test in as specified in paragraph 8(3)(i) of Annex A.(ii)Mains power supply (AC)Instruments that are powered by an AC supply shall comply with the appropriate metrological and technical requirements when operated under variations of voltage from - 15 % to + 10 % of the value marked on the instrument.Instruments shall be tested in accordance with the mains power supply (AC) test as specified in paragraph 8(3)(i) of Annex A.(iii)Battery power supply (DC)Instruments that are powered by a DC supply shall comply with the appropriate metrological and technical requirements in accordance with paragraph 4(3)(viii).Instruments shall be tested in accordance with the battery power supply (DC) test as specified in paragraph 8(3)(iv) of Annex A.
