Multifunctional Intelligent Electrical Tester: Vehicles electric system tester functions include voltage, resistance, positive and negative smart test, Multimeter mode (voltage, resistance, diode, open and short circuit, current and frequency), Oscilloscope mode, Relay test, Injector test, Component activation, Check for bad ground contacts, Follow and locate short circuits, etc. This power circuit probe tester kit is really great for troubleshooting all sorts of automotive electrical/electronic problems, which brings the user a lot of conveniences. Oscilloscope Mode & Fuel Injector Test & Relay Test: Our circuit tester can not only display the voltage, frequency, time and other parameter curves of the tested component. It can also provide 4 pulse signals to better detect the condition of the fuel injector. It can be used with any fuel pressure tester. The power circuit probe tester kit can also quickly detect whether common relays are normal, such as five-terminal relays and four-terminal relays. Self-check Protection & Buzzer Alarm: The electric circuit tester before using the automotive circuit tester, the quick self-check function of the probe can ensure that the tester is in good condition. The circuit breaker protection can protect the tool and your components from overload. It is also equipped with a voltage setting alarm. If a short circuit or fault causes the output voltage to be greater than or less than the set value of 0-5V, the device will alarm beep. 9-30V Widely Applicable: Our circuit breaker finder has many ways to not only read the unit and diagnose electrical issues but can also inject different frequencies and signals to determine and troubleshoot any problem areas. This power circuit probe tester is dedicated to testing all 9-30V vehicle electrical systems, including cars, off-road vehicles, motorcycles, trailers, trucks, boats, ATVs, RVs, excavators, etc. Probe Diagnostic Pen Function Introduction: Intelligent electrical system Test Circuit Test Relay Test Diode Test Oscilloscope Test 0-5V Power Supply Component Activation Positive and Negative Test Injector Test Online update Screen Background Changeable 9V-30V DC Vehicles Electrical System Test Light Specifications: LCD: (320*240 DPI) TFT color display Working Temperature: 0-60°C (32-140 F°) Storage Temperature: -40-70°C (-40-158 F°) External Power Supply: 12V or 24V Powered by battery Minimum Working Voltage: 9V Maximum Working Voltage: 30V Maximum Measuring Voltage: 100V Minimum Measuring Voltage: 0.1V Resistance Measurement Range: 1 ohm~200K ohm Current Measuring Range: 0~18A Maximum Continuous Current: 18A Dimension：‎12.13 x 6.77 x 4.37" Weight:3.72 lbs Power Probe Tester Package Includes: 1 x Electric System Tester 1 x Solid copper Test Probe Tip 1 x Extension Connection Line 1 x Battery Clamp 1 x Relay Test Line 1 x Probe Adapter 1 x 25Amp Fuse 1 x User Manual
