2.6 Capacity and interval

  • To record the legal capacity of a device in ORA, enter a quantity and a unit of measure.
  • If the device has one unit of measure, enter the capacity and interval in that unit of measure. If the device is switch selectable for units of measure, ensure the metric unit of measure is recorded in the Capacity field and a comment is entered in the Comments field to the effect that the device is capable of indicating in Canadian (or other) units of measure as well.
  • Do not record the interval for volumetric devices.

Gravimetric devices

  • For heavy-duty scales, the legal capacity refers to the capacity to which the device was certified during the initial examination. When the approved capacity differs from the legal capacity, record the approved capacity in the Comments field of the work order.
    • ORA does not recognize the units “tonne” and “ton”; kilograms or pounds must be used instead.

Multi-interval and multi-range scales

  • Enter the largest capacity in the Capacity field.
  • Enter the largest interval in the Interval field.
  • Enter all other capacities and intervals in the Comments field.

Volumetric measuring systems

Enter the approved maximum capacity of the device in the Capacity field. The actual flow rate at the time of testing may be captured in the Comments field of the worksheet.

Multiple dimension measuring devices

  • In the Capacity field, enter the largest certified dimension (usually, this will be length).
  • In the Comments field, enter all dimensions, starting with the largest certified dimension.
    • Enter the appropriate letter before each dimension:
      • L (length)
      • W (width)
      • H (height)
  • Enter the certified interval for each corresponding dimension in the device Comments field.
  • When a multiple dimension measuring device is configured with a multi-interval axis, record the minimum certified interval for the axis.
  • Enter other interval information in the Comments field as required.
  • In case of a difference between approved and certified dimensions or intervals, the information plate must reflect approved values.

For multi-interval and multi-range devices, enter the largest certified capacity and interval. When appropriate, enter the smaller intervals and ranges in the Comments field.

Timber dimension measuring devices

  • In the Capacity field, enter the largest certified diameter.
  • In the Interval field, enter the certified interval for the diameter.
  • In the Comments field, enter the longest approved length and length interval information.
  • In case of a difference between approved and certified dimensions or intervals, the information plate must reflect approved values.

Dynamic length measuring devices

Dynamic length measuring devices are included under device subtype 90-10, which is only applicable to Measurement Canada ORA users.

  • In the Capacity field, enter the maximum diameter that can be measured by the device.
  • In the Comments field, enter the longest approved length.
  • In case of a difference between approved and certified dimensions, the information plate must reflect approved values.
  • Enter the minimum diameter that can be measured in the Comments field as required.
