Legal Metrology Act, 2014 (Act No. 9 of 2014)RegulationsLegal Metrology Regulations, 2017Part XI : Measuring instruments and containers used for prescribed purposes51. Indication by several indicators |
(1) | Except as otherwise provided for in a technical regulation or in a certificate issued in terms of section 22 of the Act, where a measuring instrument has more than one indicator included in the verification of the measuring instrument, whether analogue or digital or whether the indication is visual or is a printed record— |
(a) | the value of the smallest graduations of all of the analogue indicators must be the same; |
(b) | the value of the smallest graduations of all of the digital indicators, including printers, must be the same; and |
(c) | the value of the smallest graduation of a digital indicator, including a printer, operating in conjunction with an analogue indicator, may be smaller than but must not be more than the value of the smallest graduation of the analogue indicator; |
(2) | The result of a measurement indicated by the several indicators, with any digital indication corrected for rounding error, must not differ, one from another, by more than the permissible error or by more than the permissible error on that indicator which has the greater value of the smallest graduation where these values differ provided that there shall be no difference in the results indicated by the several digital indicators. |
(3) | Permissible errors in visual indication or in printing must be related to the respective value of the graduations of each of the visual indicators or printers provided that, where the value of the graduations of a printer is smaller than the value of the graduations of an associated analogue indicator, the allowances must relate only to the value of the graduations of the analogue indicator and the printer may record the result of a measurement equal to the analogue indication, rounded to the nearest printer increment. |
