(1) An individual who holds a "certificate of registration":

(a) has the authority to remove an official rejection tag or mark placed on a weighing or measuring device by the authority of the bureau;

(b) may place in service, until such time as an official examination can be made, a weighing or measuring device that has been officially rejected; and

(c) may place in service, until such time as an official examination can be made, a new or used weighing or measuring device.

(2) A registered serviceperson or registered service agency may not use, in servicing commercial weighing or measuring devices, any standards or testing equipment that have not been certified by the bureau.  Equipment calibrated by another state's weights and measures laboratory that can show traceability to the national institute of standards and technology will also be recognized as equipment suitable for use by registered servicepersons or registered service agencies in this state.

(3) A registered serviceperson or registered service agency is responsible for installing, repairing and adjusting devices such that the devices are adjusted as closely as practicable to zero error.

(4) Each registered serviceperson and registered service agency shall execute a "placed-in-service" report when a device is placed in service.  The "placed-in-service" report must be on a form provided by the bureau.  Such a form must:

(a) be executed in duplicate;

(b) include the assigned registration number; and

(c) be signed by the registered serviceperson responsible for each:

(i) rejected device restored to service; or

(ii) newly installed device placed in service.

(5) Within 24 hours after a device is restored to service, or placed in service, the original of the properly executed placed-in-service report, together with any official rejection tag removed from the device, must be mailed to the bureau at the Department of Labor and Industry, Weights and Measures Bureau, P.O. Box 200516, Helena, Montana 59620-0516.  The duplicate copy of the report must be given to the owner or operator of the device.
