Key Features and Functions

The Vanguard ATRT-01B S2 is Vanguard’s third-generation micro-processor-based, single-phase, automatic, transformer-turns-ratio tester. The ATRT-01B S2 is ac-line or rechargeable-battery powered. The ATRT-01B S2 is powered by a 6-Volt, 7 Ampere-hour, lead-acid battery. The high capacity battery, coupled with the Vanguard ATRT-01B S2’s low power consuming circuitry, allows the unit to be used continuously for up to 6 hours between re-charges. A built-in charger lets the unit be used while the battery is being charged.
