Multimeter to detect the quality of the encoder

The on-site judgment of the encoder has always been a difficult problem. Here are some small methods to introduce to you for reference. You can use one of them to judge, or you can use several methods together. The on-site judgment of the encoder has always been a difficult problem. Here are some small methods to introduce to you for reference. You can use one of them to judge, or you can use several methods together.
Use the DC voltage file of the digital multimeter to measure separately. The relative ground voltage of the encoder A and the relative ground voltage of B (the encoder must be rotated at the same speed). If one of the phases has a voltage of zero 0V. Or always high, then the encoder is definitely damaged. If the voltages of phase A and B relative to 0V (digital ground) are near half of the operating supply voltage, then the encoder should be intact. The voltage of phase A or B relative to 0V is always near or near the high level, and the encoder is faulty.
