LED bar graphs show if there is voltage by looking at them.
People who are closer to a source of voltage will see a lot more LEDs light up when they sense a high voltage.
Bright flashlights can be used to light up the work area and can be used without the voltage detection function.
LED bar graphs show if there is voltage by looking at them. There are more LEDs that light up when there is a lot of voltage sensed, or when the voltage source is near. Bright flashlights can be used to light up the work area and can be used without the voltage detection function.
Today, I opened the box. It was broken.
They couldn’t sell broken things to people.
