A-VAT will beep loudly when the power outlet in test is under voltage. Consequently it allows the electrician at home to quickly know to which circuit-breaker / fuse a power outlet is connected.
CAUTION : This app is only a HELPER and not an actual Zero Voltage Verifie. THIS IS NOT A CHILD GAME, ELECTRICAL POWER IS DANGEROUS!
