  • Is it good or bad for a multimeter to have a screen light

    Is it good or bad for a multimeter to have a screen light

    A few multimeters have illuminated displays for better viewing in low light situations. You reach for your Fluke multimeter in a dark panel or dim basement, but the screen stays dark. This common frustration can stop work cold or force you to juggle a flashlight. Most Fluke multimeters lack a built-in backlight because their LCD screens use reflective technology, not the transmissive. The backlight feature on your multimeter is especially useful in low-light conditions, allowing you to read measurements without straining your eyes. The selection knob allows the user to set the multimeter to read different things such as. A digital multimeter (DMM), also known as a multitester, VOM (volt-ohm meter), or simply multimeter, is one of the most essential tools in electronics, electrical work, and industrial maintenance.
