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. 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 Package Contents: 1 x oxygen sensor signal simulator 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.Mini Type Automobile Oxygen Sensor Signal Simulator, Four-Wire Oxygen Sensor Signal SZRH A-V
