Device Manual

2.4 Device subtype

The subtype code describes in more detail the type of device. Refer to the device type and subtype tables. For information about altering the type of a previously examined gravimetric device, consult bulletin M-08.

Note 1:  A vehicle scale is considered unattended if it is:

  • designed and intended to be used without the presence of a full-time operator; or
  • used by a trained operator during the day, but not during the night.

Note 2:  If a previously certified vehicle scale is modified to allow for unattended operation, it must be recertified (see bulletin M-08). Contact your Measurement Canada regional gravimetric specialist if you have any questions on whether or not an examination is required or what limits of error are applicable.
