The universal testers
Encoder diagnostic units are multipurpose, portable diagnostic units designed to test the functions of installed incremental encoders on site. They are equipped with a display and offer an extensive range of functions. Amongst others these include TTL/HTL recognition, pulse rate acquisition, signal testing, frequency measurement, speed measurement as well as amplitude measurements. Furthermore, they are suitable for rotational frequency modulation measurements to assess the quality of the encoder attachment.
