## Description

Full description not available

## Features

- 【Intelligent test mode】it can automatically identify the voltage, resistance and positive and negative poles of the tested parts.
- 【0-5V power supply】it can set 0-5V output voltage to verify whether the wiring of the tested parts is normal. It is often used to check the wiring of ECU / ECM. And it has a voltage setting alarm, if the circuit short circuit or fault causes the voltage to be greater than or less than the set value, the device will give an alarm.
- 【Oscilloscope mode】it can display the parameter curve of the tested parts, such as voltage, frequency, time, etc.
- 【Multimeter mode】with complete multimeter parameters, it can quickly test the DC voltage, resistance, diode, current and frequency in the circuit system.
- 【Component activation mode】it can generate activation signals for components, such as lamps, motors and other on-board electronic devices. Four types of activation are provided: "MOMENT" mode, "LATCH" mode, "PULSE" mode, "SET" Circuit Breaker.
- 【Injector mode】it can output different pulse signals to the injector, and provide four pulse modes to better detect the condition of the injector.
- 【Repeater(RP) mode】it can test common automotive relays, 5-terminal relays and 4-terminal relays.
- 【Short circuit tracking and location】In most cases, a short circuit will manifest itself as a blown fuse or a tripped electrical protection device (such as a tripped circuit breaker). The AUTOOL BT280 circuit tester can diagnose and locate the cause of short circuits in circuits.
- 【2.4-inch display】2.4-inch LCD large color screen with nine-square division design. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. Moreover, the display screen is clearer, and the displayed data is more direct and clear.
- 【Double automatic circuit breaker protection】1, Short-circuit automatic protection function.2. Fusing the fuse.

    Ground connector breaks easily
  

*by A***O on Reviewed in the United States on April 21, 2023*

Ground connect snapped. Located next to inline fuse holder. Poor design. Should have used a twist on connector for fuse holder.Autool does not honor warranty. Told me I should use glue to fix this. Amazon should ban their store.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great product overall and worth the buy
  

*by O***Z on Reviewed in the United States on November 30, 2021*

If you enjoy electrical work, a machine like this can be your best friend. I used to do work without it and life was a bit difficult to get around the electrical world. I went through a different tester at first and was satisfied with it but I enjoy having and working with newer technology. I took pictures of the stuff I didn't like and for product display. It comes with extra bags etc but overall I enjoyed what I got. It's functions are more than capable of the job and what the product offers is way more advanced. The booklet does offer some teachings and I do find it useful. anyone who is looking for some understanding of the product can find it handy. The book does show great examples and step by step process as well. The only problem really was how the company handled the product. I feel like I got one of those handled products at the bottom of a delivery crate but I have nothing to complain about. The product comes with a much thicker wire compared to my last probe, the connection is extreme duty so you don't get any accident unplug. The manual can't stress enough about disconnecting product while in use and they definitely back that up with their heavy duty plug so 5 star to that. Clamps are also 4x bigger and better than my last probe and even my jump starters and that's because I own 3 jumpers. The one complaint was the the box it comes in and that's my reason for the 4 star. I like to buy high end because I would expect high end and I am happy with my product but we are all human and sometimes have accidents. If I happen to drop this product and it is in my box, I wouldn't want it to break on my first fall. The box is a very flimsy thin like material. My obd2 is much heavier duty that this box, really I'd be scared to leave it anywhere unattended. Amazon has always done great at delivering and never any issues. The issues I have had were resolved easily but I would definitely buy product again. I just hope that in the future they can provide a better box for this.
