• UPC   791541042474
• Supply Power or Ground-------For 12v-24v, Supply Power or Ground for Functional Component Testing, to determine the polarity and circuit circumstance (short/open). And this car current probe can activate the components with positive or negative current without jumper wire. Positive and negative drive----Voltage & Polarity Testing, Continuity Testing, Signal Circuit Testing , Activating Components in hand as well as in the vehicle. And Testing Trailer Lights and Connections, Activating Components W/Ground, Red/Green Polarity LED illumination, Following & Locating Short Circuits, Checking for Bad Ground Contacts，No need to connect between the battery and the testing components. Frequency measurement-----Measuring frequency of the High-tension ignition pulses and we could calculate the rotational speed of engine according to the measured frequency. Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display within 1/10th of a volt. Short Protection--------If the current is overload, it can protect your Functional Component Testing.Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display within 1/10th of a volt. It makes the device from overload. This safer measure can protect the tool and your components. Support multiple vehicles-------For cars, boats, trailers, ATV, motorhomes and many other vehicles,Also, the built-in flashlight is bright enough to light up your work area.Power probe scan kit is the most revolutionary circuit tester, which performs each type of service.The long leads allows me to easily bring power and ground from the battery to the dash or where ever you need to test.When testing a circuit, the processor is quick to respond.
