The invention relates to a clamp-shaped ammeter device and method with different acoustooptic prompting measurement operations, which comprises a current clamp and a ammeter surface body, which includes green light emitting diode, red light emitting diode, micro horn, voice module, and measuring gear rotation switch. Its characteristics are as follows: when measuring current, gear matches current value, green light emitting diode emits. At the same time, the micro-horn broadcasts the current DC current value, and the LCD displays the current measurement value synchronously. When the gear position does not match the current value, the red light-emitting diode emits a flashing red light. At the same time, the micro-horn broadcasts the voice \gear dislocation\, which prompts the need to shift and re-measure. The invention has the beneficial effects of: when measuring, the green light-emitting diode brightening prompts the measuring gear to be correct, and the voice broadcasting function prompts the measuring value; the red light-emitting diode intermittent brightening prompts the measuring gear to be wrong, and the voice broadcasting function prompts the \gear dislocation\, thereby improving the safety and accuracy of the clamp ammeter.
