High-sensitivity universal meter with insulating antiskid pad

Abstract

The invention belongs to the technical field of universal meters, and discloses a high-sensitivity universal meter with an insulating antiskid pad. The universal meter comprises a display screen, a control panel, a universal meter housing, and a universal meter pen. The surface of the universal meter housing is provided with the display screen, and a power key is disposed below the display screen. A control panel is disposed below the display screen, and the surface of the control panel is provided with a unit module. The surface of the control panel is also provided with a control rotary knob, and the surface of the control rotary knob is provided with a pointer. The right side of the control panel is provided with a meter pen accommodation box. The right side of the universal meter housing is provided with the universal meter pen, and a power line is disposed below the universal meter pen. A pen head is disposed above the universal meter pen, and the surface of the universal meter pen is provided with man-machine texture. The rear surface of the universal meter housing is provided with the antiskid pad, and a battery box is disposed below the antiskid pad. According to the invention, the universal meter housing is set to be of an insulating antiskid structure, and can effectively prevent a user from being damaged by electricity when the user uses the universal meter, thereby facilitating the improvement of safety.

Description

technical field [0001] The invention belongs to the technical field of multimeters, in particular to a high-sensitivity multimeter with an insulating anti-skid pad. Background technique [0002] With the continuous progress and development of science and technology, more and more scientific and technological products have been produced in various fields, and people are becoming more and more accustomed to accepting and using them. The multimeter is a magnetoelectric type that can measure various electrical parameters Instruments are widely used in this field, and there are many multimeters on the market at present, but there are still some shortcomings. For example, the multimeter case has no insulating layer, resulting in inaccurate measurement results and relatively low sensitivity. Make the error that exists is very big, be unfavorable for the utilization of actual situation, there are problems such as incomplete contact of table pen. [0003] To sum up, the problems exi...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the housing of the multimeter has no insulating layer; moreover, the existing multimeter has a poor ability to process data, resulting in inaccurate measurement results and relatively low sensitivity, resulting in large errors , which is not conducive to the application of the actual situation, and there are problems such as incomplete contact of the test pen
