Calculate gravity tolerance for scales

The gravity tolerance application calculates the change in gravity between two locations in Canada. This helps you find out whether a non-automatic weighing device can be inspected in one geographic location in Canada, and then put into service in another without requiring readjustment. The application works by calculating the change in gravity percentage and other calibration information. The gravity data generated by the application is provided by Natural Resources Canada's geodetic reference systems.

Users

The application is intended for users who are calculating gravity tolerance for a non-automatic scale and are:

  • authorized service providers
  • Measurement Canada inspectors
  • measuring device manufacturers
  • measuring device dealers

Before you start

You will need the following information in order to use the gravity calculator:

  • detailed information about your scale (class, capacity, capacity unit, verification interval, verification interval unit)
  • the postal code or longitude and latitude of the location where the device was inspected
  • the postal code or longitude and latitude of the location where the device was moved to
