If it will not zero then you have problems. The M2R repair manual lists three causes: either the adjusting fork is damaged; the hair spring is disconnected from the adjusting fork; or, the meter hair spring(s) is (are) defective. The first two are economical to fix while the third requires a new meter movement. The meter movements are available new but cost more than another used working meter. If you are very very handy it is possible to fabricate new hairsprings but it is time consuming delicate work. Unfortunately, in my experience, hairspring failures are not uncommon while the other two problems are. So take the battery out and try setting the zero then. Hopefully it will OK.
