Aitek tachometer parameter settings

Set the threshold level for the input signal; generally, if there is a lot of noise in the circuit, you can try raising the HIGH level by 0.2 V.

The function of logic levels (logic low/logic high) is to compare them with the waveform generated by the speed sensor, thereby determining the speed. 2. Appendix 2: Quick Start Guide: Setting the logic levels appropriate for the sensor (logic low/logic high), typically 20% and 80% of the positive side of the sensor waveform. The default value will apply to almost all active sensors and many passive sensors. Passive sensors may need to be modified at low speeds and/or large gaps (note: since the actual voltage is low at such times, setting it too high will prevent the rotation speed from being measured). See Attachment 2. For specific setup instructions, see the user manual in Attachment 3. The default values are Logic Low = 0.6 volts, High = 2.6 volts (TTL). 4. Fine-tuning can be done by referring to the sensor data in Attachment 1.
