In Montana any weighing or measuring device, either new and being installed for the first time, or being returned to commercial service after repairs or reconditioning, must be "placed in service" by a registered service company or individual.
"Placed in Service" means that a registered individual using certified testing apparatus has inspected and tested the device and certifies that the device meets all applicable rules and regulations. After certifying the device, the registered repair person will affix their seal on the device, which will allow that device to be used commercially until such time as the device has an official inspection performed on it by a Bureau official.
