The present invention is a portable testing apparatus for field testing rotary shaft encoders. The rotary shaft encoder is mounted in connection to a motor disposed on a mounting panel whose direction and speed of rotation is controlled by a motor controller. The rotatable shaft of the rotary shaft encoder is coupled to the motor shaft via a shaft couple. A multiple wire connector is employed to connect to the plurality of connection wires of the rotary shaft encoder. Each connection wire of the rotary shaft encoder is connected to one of a plurality of single pole, multiple throw load selection switches. This permits connection of an operator selected one of a predetermined set of voltages and loads to each connection wire of the shaft encoder forming a circuit simulating its use. An output terminal connected to each connection wire of the rotary shaft encoded permits the signal on these corresponding connection wires to be monitored. In the preferred embodiment the testing apparatus is mounted in an attache which may be closed for transport and opened for use. |
