Weights and Measures Regulations (C.R.C., c. 1605)

135. Electronic digital means of indication for a machine shall conform to the following specifications:

• (a) all digits shall be of the same height;

• (b) the digits representing a decimal submultiple of the unit shall be set apart by a decimal point or comma; and

• (c) the brightness of the electronically displayed digits and other information shall be such that they may be easily read under normal conditions of use.

136. Associated with any digital registration by a machine there shall be suitably located defining words and the name, symbol or abbreviation for the unit or units of measurement appropriate in size and such that they will not become obliterated or illegible under normal conditions of use of the machine.

137. Indicators and printers for monetary values shall conform to the same specifications as indicators and printers for registration of units of quantity.

138. Within such limits of repeatability as may be required by these Regulations or by specifications established by the Minister, a machine shall be capable of repeating its registrations for each identical load or quantity delivered regardless of repeated manipulations of any or all of the elements of the machine in a manner approximating normal conditions of use of the machine.

• 139. (1) Subject to subsection (2), where a machine has or is installed with two or more means of registration that have the same units of measurement, the registrations shall be in accordance with the following criteria:

  • (a) in the case of electronic digital means of registration, the registrations thereof shall

    • (i) where the values of minimum increment of registration are the same, be in exact agreement, or

    • (ii) where the values of minimum increment of registration are not the same, be in agreement within 0.6 times the largest of those values of minimum increment of registration;

  • (b) in the case of mechanical digital means of registration, the registrations thereof shall be in agreement within 0.6 times the largest of the values of minimum increment of registration;

  • (c) in the case of analogue means of registration, the registrations thereof shall be in agreement within 0.25 times the largest of the values of minimum increment of registration; and

  • (d) in the case of combined digital and analogue means of registration, the registrations thereof shall be in agreement within 0.6 times the largest of the values of minimum increment of registration.

• (2) A means of providing analogue registration that is of the servo-follower type and that is installed prior to January 1, 1976 shall be in agreement with any other analogue or digital means of registration connected to the same machine within twice the finest graduation.

140. The registration of monetary value on a machine provided with means of registration for monetary value shall be in mathematical agreement with the quantity indication and unit price, within such monetary limits as may be allowed by these Regulations or by specifications established by the Minister and the machine shall have words or symbols to differentiate clearly between the monetary value and the quantity registrations.
