Encoder diagnostic unit

The handheld encoder diagnostic unit EDU 100 is used to test incremental encoders are functioning properly. Easy to operate via the clearly laid out keypad, this is an essential tool for personnel charged with commissioning, repair and maintenance tasks to quickly test encoder signals. As a special feature the unit offers rotational frequency modulation measurements, for example to assess the assembly quality of hollow-shaft devices.

Particularly distinguishing features of the handheld diagnostic unit are:

Large, graphic displayMeasurement data memoryRotational frequency modulation measurements possibleIntegrated charging functionUSB interface to control/display via PC/laptop
