Abstract

The invention relates to a universal meter device and a method for prompting different measurement values by using different sound and light. The universal meter device comprises a meter body and a meter pen, and the meter body comprises a green light emitting diode, a red light emitting diode, a voice module, a miniature loudspeaker and a measurement gear rotary switch. The device is characterized in that during measurement, the gear switch is rotated to a required gear, and the current gear is broadcasted through voice; when the measurement gear is consistent with a measurement value, the green light emitting diode emits green light, the miniature loudspeaker broadcasts the current measurement value, and a liquid crystal digital display screen displays the current measurement value; whenthe measurement gear does not accord with the measurement value, a protection circuit in a measurement module automatically disconnects a measurement circuit, the red light emitting diode gives an intermittent red light alarm, and meanwhile, the miniature loudspeaker broadcasts voice of gear errors to prompt gear-shifting re-measuring. The beneficial effects of the invention are that during measurement, the green light emitting diode emits light to prompt that measurement is correct, and the miniature loudspeaker broadcasts a correct measurement value; the red light emitting diode emits lightdiscontinuously, meanwhile, the miniature loudspeaker broadcasts voice of gear errors and prompts that gear shifting retesting needs to be carried out, and therefore the safety and accuracy of universal meter measurement are improved.

Description

technical field [0001] The invention relates to a multimeter device and method for prompting different measurement values ​​with different sound and light, which belongs to the related technical field of power electronics. Background technique [0002] At present, there are only two types of multimeters: mechanical pointer type and liquid crystal digital display multimeter. There are no multimeters with different color light prompts and simultaneous voice broadcast of measured values. Contents of the invention [0003] Purpose of the present invention: In order to overcome the above-mentioned deficiencies, a novel multimeter device and measurement method are provided. During measurement, the green light-emitting diode lights up to indicate that the measurement is correct, and at the same time the micro-speaker broadcasts the measured value; the red light-emitting diode lights up intermittently, and the voice broadcasts "file "Position error", prompting the measurement oper...
