PowerScan Battery Electric System Probe Circuit Test Oscilloscope Diagnostic AUTOOL BT280 Car Electric Circuit Tester Features : 1. [Multimeter Mode&Smart Test]: AUTOOL BT280 Electric System Tester is covered with comprehensive parameters of Multimeter, it can quickly test and automatically identified the Voltage, resistance, Positive and Negative poles of the tested component, which brings the user a lot of conveniences. 2. [Oscilloscope Mode&Relay Test]: AUTOOL BT280 is not only able to display the parameter curve diagram of the tested component, such as voltage, frequency, time, etc, but also can test the common automotive relay, like 5-terminal relays, and 4-terminal relays. 3. [Component Activation&Injector Mode]: It can generate "Active" signals for components, such as lights, motors, and other on-board electronic devices. Also different pulse signals can be output to the injector, which provides 4 pulse modes to better detect the condition of the injector. 4. [0-5V Power Supply&Voltage Alarm]: Capable of setting 0-5V output voltage, used to verify the wiring condition of the tested component. Equipped with voltage setting alarm. If a short circuit or fault causes the voltage to be greater than or less than the set value, the device will alarm.
