1) Vibration Sensor
Vibration sensor must be located where you are trying to measure. If not incorrectly installed, guideline will be invalided.
Vibration sensor must be located where you are trying to measure. If not incorrectly installed, guideline will be invalided.
Vibration sensor is designed for use with a magnet. If a magnet does not work where area is not a metal part,
you can use a glue to attach it.
Please refer to the provided images.(Vehicle Locations)
According to environmental condition, sensitivity may change. Sensor must be checked periodically (6~12month).
2) Noise Sensor
Noise sensor must be located where you are trying to measure. If not incorrectly installed, guideline will be
invalided.
Noise sensor is designed for use with a magnetic stand.
Sensor signal can be effected by environmental noise.
According to environmental condition, sensitivity may change. Sensor must be checked periodically(6~12month).
3) Photo Sensor (Rotational speed Sensor)
Install the Photo sensor pointed to the reflective tape. Reflective tape must be located in the P/Shaft.
Install the Photo sensor pointed to the reflective tape. Reflective tape must be located in the P/Shaft.
Photo sensor is designed for use with a magnetic stand.
Place the magnetic stand at the bottom of the Differential gear Housing and locate the sensor perpendicularly
to the reflective tape.
Photo sensor and vibration sensor are coupled together for balancing. When using a Photo sensor only, RPM
can be checked. Use the cable in a safe manner.
