Ⅱ. Key Selling Points ⚡ All-in-One Automotive Diagnostics Precision & Versatility: The HP-770K’s True RMS ensures accurate AC/DC voltage/current readings even in noisy environments, while the HP-705A captures engine RPM, ignition signals, and dwell angles for pinpoint troubleshooting. Critical for Mechanics: Measure fuel injector pulse width (ms), duty cycle of solenoids, and spark plug health to diagnose misfires, poor fuel economy, or stalling. Safety First: CAT III 1000V protection, non-contact voltage detection (NCV), and fused terminals prevent accidents during high-voltage tests. Time-Saving Tools: Auto-ranging, data/peak hold, and backlit display let you work faster in dim garages.
