(2) Set the MODE on the front board of the tester as the encoder for testing, and the corresponding table for the encoder is as follows:

(3) Turn the switch in the lower left corner of the front version of the testing machine to Analog Check.

(4) Plug in a 5V power supply in the later version.

(5) Provide a speed higher than 800 revolutions per minute for the test motor to operate through an external coupling.

(6) Turn on the power of the testing machine to ON.

3. Testing:

(1) Press the ECPOWER button to provide power to the encoder.

(2) Simultaneously press the SHIFT+F3 keys, and the testing machine will start testing. After the test is completed, the results will be displayed. The result comparison is shown in the following figure:

The error code is as follows:
