⚡ At a Glance
- • Detection Range: 0.8–100V DC range with automatic AC/DC, polarity, resistance and continuity detection
- • Best for: DIY mechanics and professional automotive technicians who need quick, reliable circuit checks
- • Not ideal for: Users needing measurements above 100V or specialised laboratory-grade testing
Smart mode auto-selects measurement type and range for simpler operation. Green backlit LED shows 0.1V resolution for clear daytime and nighttime reading.
Faster, error-free checks - with Smart Mode automatic detection
Smart Mode automatically identifies AC or DC voltage, polarity, resistance and continuity, then selects the optimal measurement range for highest precision. The auto-ranging removes manual range selection and reduces the chance of user error.
Quicker diagnosis of faults without fiddling with settings, ideal when testing headlights, taillights and fuse connections. Less time spent switching ranges means more efficient troubleshooting.
Broader vehicle coverage - thanks to a 0.8–100V DC testing range
The tester measures DC voltages from 0.8V up to 100V, extending beyond the typical 60V limit of many automotive testers. The wider range suits varied automotive circuits and battery checks.
Able to examine most car and light commercial electrical circuits without needing a second tool. Useful for technicians who encounter diverse vehicle electrics.
Safer, more comfortable handling - with probe guard and long spring wire
A thick probe guard reduces the risk of accidental stab wounds while the 78.74-inch PU spring wire offers durable flex and extended reach. A large alligator clip supports one-hand connection to ground points.
Hands stay clear of hot or awkward components during testing, and the long, springy cable improves access in cramped engine bays. One-hand clipping speeds up routine checks.
