Red led volt meter dc 7V-30V doesn't require a power
In addition to the Auto Dimming feature our meter now incorporates REVERSE POLARITY PROTECTION. This feature protects the meter from failure should the meter's positive (+) and negative (-) leads be accidentally connected in reverse order. NO MORE BURNED OUT METERS should you hook up the power leads incorrectly!
