How to measure the filament voltage supplied by the high voltage packet of TV set by digital multimeter
Digital multimeter (DMM) is the electronic instrument used in electrical measurement. It can have many special features, but the main function is to the voltage, resistance and current measurement, digital multimeter, as a multi-purpose electronic measuring instrument is mainly used for the modernization of the physical, electrical and electronic measurement field.
A digital multimeter has a portable device for basic troubleshooting, and a device placed in the workbench, with a resolution of up to seven or eight bits.
Accurate values of the picture tube filament voltage can be obtained only if the true RMS meter such as FLUKE 289 is used.Digital multimeter, a multi-purpose electronic measuring instrument, voltage meter, ammeter, generally includes an ohmmeter function, sometimes referred to as the multimeter, multi meter, multimeter, or three meter.
