Home Improvement Tools & Testers By AIOMEST

• PRO AUTO DIAGNOSTICS AIMOEST engine analyzer AI-770K measure RPM tach (60-12000), pulse width (0.1-10ms), duty cycle (1.0-99.0%), and test dwell angle (0-90.0?) for 4, 5, 6, and 8 cylinder engines. Perfect for automotive professional mechanics and DIY car/vehicle enthusiasts.Requires optional AI-705A Inductive Clamp for RPM measurement (NOT Included).
• VERSATILE MULTIMETER The automotive dwell meter AI-770K has comprehensive electrical features to assist in electric troubleshooting, such as accurately measure DC voltage (0.01mV-1000V), AC volt (TRMS 0.01mV-750V), DC/AC current (0.1?A-20A), resistance ohm (0.1?-60M?), capacitance (1pF-60mF), and temperature (-4?F-1832?F). Includes diode test, continuity buzzer, and frequency testing.
• SMART LCD DISPLAY Features a 6000 count crystal clear LCD screen with auto-backlight sensor that adjusts to ambient light conditions. Includes auto-zero, auto-polarity, auto-range, and auto power-off after 15 minutes of inactivity. \"OL\" indicator for over-range and 3 readings/second for quick results.
• ADVANCED SAFETY FEATURES Non-contact AC voltage (NCV) detection, data hold function, Max/Min measurements, and PeakHold to capture AC voltage/current peaks. Low battery indicator ensures reliable operation.
• ACCESSORIES & WARRANTY Handheld DMM True RMS multimeter comes with test leads, temperature probe, portable ammeter/voltmeter carrying case and 365 days quality warranty. Built to withstand demanding automotive environments, making it an essential tool for any garage or workshop.
