DIAGNOSTIC TOOL

• Multimeter Tester: Detects 1000V DC and AC voltages, measures 200mA DC and AC and detects Resistance and Diodes.
• Oscilloscope Function: The handheld oscilloscope has a 500kHz bandwidth. One-button automatic display of the measured waveform.
• Ignition Diagnostic: Select the engine cylinder type and ignition and calculate the speed of different engine cylinders.
• Wire Instructions
• 1Hz~1MHz Signal Frequency: The measurement needs to connect to a valid signal source with a voltage greater than 1V.
• Cranking Test: The vehicle start test indicates normal operation if the minimum battery voltage is above 9.6V. If it drops below 9.6V, it may indicate battery aging.
• Injector Test: The multimeter can drive the injector for testing, and can also detect the real-time injector signal. It can test electromagnetic injectors, including GDI injectors, but doesn’t support 120V injectors
• Analog Signal Test:  The multimeter can simulate 5V square wave and 5Vpp sine wave signals, and it can also connect to a battery for 12V square wave signals using a multifunction detection cable.
• True-RMS Multimeter: Automatically ranging true mean squared (TRMS) technology for increased accuracy. The True-RMS Multimeter is ideal for a wide variety of electrical and electronic testing applications
• Auto Range Function: Automatically displays the measured data, saving the tedious process of manually selecting the range of measured values
