Abstract
Abstract A testing device for testing a water meter register unit which comprises a rotatable magnet and which causes signals to be transmitted to a remote register: the testing device includes a housing for batteries, a motor and a rotatable magnet driven by the motor. The magnet is located within a chamber on which are supports for the water meter register unit. The batteries are connected to the motor through a switch in either parallel or series, and adapter rings enable the holding of register units of various sizes.
