Different colors identify voltage rangeA built-in LED work light allows for increased visibility in low-lit areas and automatic shut-off after 5 minutes helps preserve battery lifeAuto-offPocket clipBlade tip for checking outletsIt does so by using a uniquely colored LED indicators and audible tonesDelivering the clearest indication of these two voltage rangesThe expanded sensitivity range of 10 - 49 V offers the ability to detect voltage in common systems that would normally go undetected when using a standard voltage detectorThese systems include LED lighting, fire detection and suppression systems, HVAC controls and security and access controls, along with many othersThe 10 - 1000 V dual range voltage detector not only detects, but also differentiates 10 to 49 V from the standard voltage range of 50 to 1000 VIt does so by using a uniquely colored LED indicators and audible tones, delivering the clearest indication of these two voltage ranges
