Technical Field

[0001] This utility model relates to a measuring instrument, specifically a measuring instrument that combines the functions of a digital multimeter and a walkie-talkie. Background Technology

[0002] With the continuous development of electronic measurement and communication technologies, digital multimeters, as a commonly used measuring tool, have been widely applied in various fields such as electrical engineering, electronic repair, and industrial debugging. Existing digital multimeters typically possess measurement functions for parameters such as voltage, current, resistance, capacitance, diodes, and temperature, and are characterized by high measurement accuracy and ease of operation. On the other hand, walkie-talkies, as a convenient voice communication tool, are also widely used in engineering construction, on-site maintenance, and emergency operations to enable real-time voice communication between personnel.

[0003] In practical applications, operators often need to simultaneously rely on digital multimeters for electrical parameter measurements and walkie-talkies for voice communication. For example, during high-voltage maintenance, remote collaboration, or multi-point inspections, operators need to accurately read electrical parameters and promptly relay the measurement results to other collaborators or receive operational instructions. However, most digital multimeters and walkie-talkies on the market are currently standalone devices, requiring users to carry and operate two separate terminals. This results in a heavy equipment burden, cumbersome operation, and an inability to achieve efficient data and voice communication, impacting measurement efficiency and on-site safety.

[0004] Therefore, how to integrate the functions of a digital multimeter and a walkie-talkie into the same device, so as to meet both the requirements of accurate electrical parameter measurement and efficient voice communication, has become an urgent problem to be solved in the field of measurement instrument technology.

Control chip 1 manages the status and switches signals for the intercom function. Users can quickly enable or exit the intercom mode via dial 13, and the system automatically switches audio channels without interfering with the measurement function.

[0026] The power module 3 contains a lithium battery, a voltage regulator circuit, and other units, which provide a stable power supply for core components such as the control chip 1, the multimeter measurement module 4, and the walkie-talkie audio signal processing module 10, ensuring the reliable operation of the whole machine.
