WALFRONT Digital Multimeter Digital Rechargeable Automotive Engine Analyzer Data Hold Tester for Car Diagnostics

1. RPM Engine Speed Measurement: Measure the number of rotations per minute of the engine spindle, selecting the appropriate engine stroke for accurate RPM measurement with the RPM key. 2. Dwell Angle Measurement: Measuring the dwell angle of the ignition system is crucial. Dwell measurement refers to the duration the breaker switch remains closed while the camshaft rotates. Select the cylinder count for accurate measurement. 3. Automotive Pulse Width Measurement (mS PULSE): Measure fuel injection system pulse width, switch to PULSE mode, connect the black test pen to the fuel injector ground or a car ground, start the engine to measure pulse width time. 4. NCV Detection: Switch to NCV function, display EF, when the NCV sensing area at the bottom left of the meter detects AC voltage, the meter emits an audible reminder and the LCD analog bar displays the sensing strength. 5. Flip Top Large Screen Flexibility: Adjust the angle up to 180° for convenient measurement, easy to carry and place, suitable for on the way automotive diagnostics. 6. Live Neutral Wire Detection: Distinguish between neutral and , instantly detect fire wire installation with an alarm and no for neutral lines. 7. USB Charging Plug and Play: Say goodbye to the age of batteries with USB data cable charging for the built in 3.7V 1800mAh li battery, offering easy charging through USB li direct charging for quick and convenient use.
