Mini Type Automobile Oxygen Sensor Signal Simulator, four-wire Oxygen Sensor Signal 1. This instrument is a special equipment for oxygen sensor signal simulation; 2. dedicated to four-wire oxygen sensor signal,does not support broadband oxygen sensor signal simulation. 3. the instrument needs external 12V-24V power supply to work; 4. need to disconnect the original car oxygen sensor signal line, otherwise the original car oxygen sensor signal and S03 simulator signal will interfere with each other.<br><br>Measure the output signal of the S03 simulator: 1, there are 8 signal voltage indicators on the simulator, the signal voltage can be adjusted through the knob, the signal light indicates the average voltage of the signal; 2, Read oxygen sensor data stream with vehicle fault detector; 3, use the oscilloscope to view the signal waveform; 4, use a multimeter 5V file to measure the signal voltage; The normal signal voltage is 0-0.9V constantly changing. Tips: The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use Color: Black Material: Plastic<br><br>Package Contents: 1 x oxygen sensor signal simulator<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
