ATRT-01B Transformer Turns-Ratio Tester

The ATRT-01B is ac-line or rechargeable-battery powered transformer turns-ratio tester. The ATRT-01B is powered by a 6-Volt, 7 Ampere-hour, lead-acid battery. This high capacity, plus the low-power consumption circuitry allows the ATRT-01B to be used continuously for up to 6 hours between recharges. A built-in charger lets the ATRT-01B be used while the battery is being charged.
