This Meter features a vacuum fluorescent display (VFD) A VFD operates on the principle of cathodoluminescence, roughly similar to a cathode ray tube, but operating at much lower voltages. Each tube in a VFD has a phosphor-coated carbon anode that is bombarded by electrons emitted from the cathode filament. Each tube in a VFD is a triode vacuum tube because it also has a mesh control grid.
 
Unlike liquid crystal displays, a VFD emits a very bright light with high contrast and can support display elements of various colors. Due to the conditions of (VFD) there is a high DC Voltage present of about 38V So don't touch the VFD Pins when powered up.
