Abstract
The utility model discloses a novel voltmeter. The novel voltmeter includes a housing body; a pointer-type voltmeter unit and a digital-type voltmeter unit are arranged inside the housing body; the pointer-type voltmeter unit is connected in parallel with the digital-type voltmeter unit; the pointer-type voltmeter unit is provided with a pointer-type voltmeter switch; and the digital-type voltmeter unit is provided with a digital-type voltmeter switch. By means of the above manner, with the novel voltmeter of the utility model adopted, numeric reading can be performed through adopting the pointer-type voltmeter, a voltage value can be roughly measured, such that numeric reading ability of students can be trained; accurate measurement can be performed through the digital-type voltmeter; and therefore, the novel voltmeter is of simplicity and practicability.
Description
Technical field
The utility model relates to electronic instrument technology field, particularly relates to a kind of Novel voltmeter.
Background technology
Voltage table is a kind of instrument of measuring voltage.Voltage table is divided into traditional electromagnetic induction needle dc voltmeter and digital voltmeter.Traditional electromagnetic induction needle dc voltmeter mainly is used in school instruction aspect, the reading ability of exercise student '; Digital voltmeter mainly is used in measures the research aspect, and it is not only convenient to use, but also has advantages of that precision is higher.
At present, also do not see the voltage table that traditional electromagnetic induction needle dc voltmeter and digital voltmeter are combined.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of Novel voltmeter, can solve problems of the prior art, namely can adopt needle dc voltmeter to come reading, the rough measure magnitude of voltage, the reading ability of exercise student ', can accurately measure by digital voltmeter again, simple and practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Novel voltmeter is provided, comprise: shell body, described shell body inside is provided with pointer voltage table unit and digital voltage table unit, described pointer voltage table unit and digital voltage table unit are in parallel, described pointer voltage table unit is provided with the needle dc voltmeter switch, and described digital voltage table unit is provided with the digital voltmeter switch.
In preferred embodiment of the utility model, described shell body is provided with the inlet wire joint pin and joint pin occurs.
In preferred embodiment of the utility model, described shell body is waterproof case.
The beneficial effects of the utility model are: the Novel voltmeter that the utility model discloses, and namely can adopt needle dc voltmeter to come reading, the rough measure magnitude of voltage, the reading ability of exercise student ' can accurately be measured by digital voltmeter again, and is simple and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model Novel voltmeter one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, shell body, 2, the pointer voltage table unit, 3, the digital voltage table unit, 4, the needle dc voltmeter switch, 5, the digital voltmeter switch.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind of Novel voltmeter, comprise: shell body 1, described shell body 1 inside is provided with pointer voltage table unit 2 and digital voltage table unit 3, described pointer voltage table unit 2 and 3 parallel connections of digital voltage table unit, described pointer voltage table unit 2 is provided with needle dc voltmeter switch 4, and described digital voltage table unit 3 is provided with digital voltmeter switch 5.
The user namely can adopt pointer voltage table unit 2 to come reading, and the rough measure magnitude of voltage is tempered the reading ability, can accurately measure by digital voltage table unit 3 again.
When the user only need to use a kind of in pointer voltage table unit 2 and digital voltage table unit 3, can come by described needle dc voltmeter switch 4 or digital voltmeter switch 5 break-make of steering needle formula voltage table unit 2 or digital voltage table unit 3.
Described shell body 1 is provided with the inlet wire joint pin and joint pin occurs, is used for being connected with circuit.
Described shell body 1 is waterproof case, makes voltage table have good water resistance.
The Novel voltmeter that the utility model discloses namely can adopt needle dc voltmeter to come reading, the rough measure magnitude of voltage, and the reading ability of exercise student ' can accurately be measured by digital voltmeter again, and is simple and practical.
