Product Details

✓Ultimate Auto Power Circuit Tester - OBDRESOURCE CP40 automotive circuit probe tester covers almost all probe tester function available on the market,a revolutionary diagnostic solution for 0 - 80V automotive electrical system issues.It supports various tests: Electric circuits (locate short circuits,continuity or open circuit,voltage & polarity, checking bad grounding,test trailer lights, fuse,diode,relay),Battery health (crank, charging, load capabilities,voltage ),Component activation (lights, fans, motors etc),Fuel injectors,Oscilloscope.A must have in toolbox for car owners, professional mechanics, or automotive DIY enthusiasts to troubleshoot vehicle electrical circuit issues
✓All-in-one Money Saver - This super circuit tester combines digital multimeter,vehicle battery tester oscilloscope analysis and fuel Injector tester into one device,providing efficient troubleshooting for 6-32V cars trucks SUV tractor boat RV& motorcycles without the purchase/need for separate tools
✓Versatile Entry-Level Digital Multimeter - Equipped with 6 working modes including Voltage(DC,AC for Min & Max voltage, duty cycle capacitance and frequency), resistance, on/ off circuit (resistance <100Ω,continuity circuit),diode,polarity,frequency.This auto-ranging smart DVOM allows to quick switch between all measurement tasks without selecting range,can accurately measures AC/DC voltage up to 80V,8A,200KΩ resistance.Works as a voltmeter, ohmmeter. Additionally, the screen can be flipped 180 degrees in this mode for complex maintenance scenarios
✓Universal Fuel Injector Tester - Features with 5 pulse signal modes,it is designed to check injectors individually for common faults like being stuck,blocked, leaking, damaged or insufficient combustion and can combine with the cleaning adapters and cleaner (not included) can quickly clean and optimize the injectors performance.In oscilloscope,can obtain the injector waveform graph and catch the problem more intuitively than digital display ,can be used with any fuel pressure tester.Collecting vehicle signal and simulating function provides more experience in maintaining injectors
✓Battery Tester - Perform start - up test (cranking), charging test, load capabilities test and battery waveform monitoring for different types of 12/24V batteries (ordinary, AGM, GEL, EFB) to check battery SOH and SOC status and can auto-identify the battery voltage and make corresponding prompt
✓Handheld Oscilloscope - Capture observed waveform of camshaft signal,crankshaft signal,Injector signal,EGR throttle signal,CAN Polarity for accurate voltage signal analysis,can outputs sine, square, triangle, saw-tooth waveform,the maximum waveform output frequency can reach 2MHz and 1M Hz real-time sampling rate
✓Component Activation-Support generating 3 activation signal (Moment, Latch & Pulse) to components(radiator fans,blower motor, power window, windshield wiper,rear window defroster,headlights fuse and other ) for accurate troubleshooting the integrity of components in hand or in the vehicle.Sim voltage mode provides 0~5V supply to check a variety of sensors and signal circuits
