Como usar uma caneta de polaridade • IJ2155

Digital Multi-Test Pen: Examples of using the basic functions of the Injetec pen. I'm always asked to make videos about using a polarity pen, especially by beginner mechanics and car owners. And it's really worthwhile for everyone to have this inexpensive and simple tool. In this video, I begin the presentation of the digital multi-function test pen from @injetecferramentasautomoti3015. Unfortunately, I won't be able to show all the functions in just one video. And as you can see in the recording, the sky suddenly opened up in the east zone of Belo Horizonte, and I had to stop filming. Functions of the Injetec digital multi-test pen: F01 - Battery voltage test in V F02 - Voltage and polarity at the probe tip in dV (decivolt) F03 - Injection time in ms (not µs) F04 - Frequency in Hz F05 - Duty Cycle in % (duty cycle) F06 - Sensor voltage in cV (centivot) Chapters: 0:00 Introduction - How to use the test pen 0:58 Understanding the digital multi-test pen 2:23 Maxi-fuse test with the multi-test pen 3:52 Positive and negative power supply test - Ex. with headlight 5:11 Power supply test - OBDII connector 7:17 Power supply and pulse test on the ignition coil 9:05 Power supply, pulse and injection time test on the injector 11:10 Frequency and pulse test of the rotation sensor 12:32 Power supply, frequency and duty cycle test on the Canister valve 14:49 Lambda probe tests with digital multimeter pen 15:50 Positive test of heating probe (SUB) 16:26 Negative test of lambda probe heating - Hz and % 17:09 Lambda probe signal test (mV) 18:21 Conclusions about the digital multimeter pen Full description of the Injetec Digital Multimeter Pen: https://injetecferramentas.com.br/pro...
