The zero pulse is used to reset a measurement when a Z pulse is recognized. The only change to the setup is to check the Encoder zero check box . This will reset the counter value to 0 when a zero pulse is passed. We also need to set the number of Encoder pulses for internal calculations (512 in this case).

Encoder channel setup

The picture below shows the operation. The red curve is the zero signal, and the orange curve is encoder outputthe . When a pulse is detected on the zero pulse input, the counter value resets to 0 .

Analysis - encoder with zero pulse

The picture below is of a zoomed region-in of the recorder. It shows that the encoder resets the value on the zero pulse and continues to count up on the rising edges of the A signal.
