Greenlee GT13 Non-Contact-G Voltage Detector

Using the Greenlee GT13 is easy. First, insert the two provided 1.5V AAA batteries. Then, bring the detector close to the area you want to test, like an outlet or a wire. If there's voltage between 50V and 1000V AC, you'll get an audible and visual alert. The built - in flashlight can be used in dark places to help you see what you're doing. Remember, this is a non - contact detector, so you don't need to touch the electrical components directly. For maintenance, keep the detector clean and dry. If it's not working properly, check the batteries first. Also, let it self - test before each use to make sure the circuit is okay. When you're done using it, just let it sit idle for 5 minutes, and it will turn off automatically to save battery power.
