Multi-Standard Compatibility and Broad Battery Support
Designed for universal service, the UT673A supports a wide range of standard lead-acid battery chemistries, including traditional Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, and Enhanced Flooded Batteries (EFB). The instrument accommodates battery capacities ranging from 3Ah to 250Ah and seamlessly evaluates them across major international rating standards, including CCA (40 to 2000), BCI (40 to 2000), CA (40 to 2000), MCA (40 to 2000), JIS (26A17 to 245H52), DIN (40 to 1400), IEC (40 to 1400), EN (40 to 2000), SAE (40 to 2000), and AH (3 to 250Ah).
Integrated 12V/24V Cranking and Charging System Analysis
Beyond individual battery health, the UT673A provides essential diagnostics for complete vehicle electrical systems. Operating across a broad DC voltage range of 7V to 30V DC, it performs real-time cranking system tests to evaluate starter motor performance during engine turn-over and charging system tests to verify alternator output and diode ripple integrity on both 12V passenger cars and 24V commercial electrical networks.
Enhanced Safety Circuitry and Rugged Design
Built for demanding workshop environments, the UT673A incorporates key electrical safety protections, including reverse connection protection, over-voltage input defense, and automated contact prompts for poor clamp connections. The device operates directly off the target battery voltage, eliminating the need for internal battery replacement. Test results are displayed clearly on a high-contrast 128x64 monochrome dot-matrix screen, ensuring effortless readability under varying garage lighting conditions.
