The P200 stands out because it combines a multimeter, oscilloscope mode, relay and injector testing, and an activating probe with a long 20ft lead, making on-car diagnosis quicker and less fiddly than hauling multiple meters and lights.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultimeter \u0026amp; Oscilloscope:\u003c\/strong\u003e Offers DC voltage, resistance, diode, current and frequency checks plus a waveform view to spot signal problems that a basic meter would miss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActivating Components:\u003c\/strong\u003e Applies battery power or ground at the probe tip so the user can energize lights, motors or solenoids to test operation without rewiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay Test:\u003c\/strong\u003e Built-in relay testing lets you verify relay coil and contact function quickly when troubleshooting lights and accessories on the vehicle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Injector Cleaning\/Test:\u003c\/strong\u003e Four selectable pulse signals allow injector activation for bench checks and combined cleaning cycles for maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart Auto-Range:\u003c\/strong\u003e The tester auto-detects polarity and range, showing parameters on the HD LCD so the operator avoids manual range switching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong Reach \u0026amp; Lighting:\u003c\/strong\u003e A 20ft extension cable and LED on the probe help reach deep or awkward connectors without moving the vehicle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe P200 is aimed at professional mechanics, mobile technicians and committed DIYers who routinely diagnose electrical faults, test relays, trace signals, and need the occasional oscilloscope view without carrying separate bench gear.
