Description
[technical field]
The present invention relates to a kind of multimeter, relate in particular to a kind of multimeter with small display.
[background technology]
Present widely used multimeter comprises: a multimeter body and two redness, black test pencils that structure is identical.Wherein, the multimeter body partly is comprised of gauge outfit, metering circuit, test pencil socket and switch etc.
Measuring circuit is the various measured circuit that are transformed into the small DC current that is fit to the gauge outfit measurement, it forms it by resistance, semiconductor element and battery and can with various measured (such as electric current, voltage, resistance etc.), different range, send into gauge outfit through the unified small DC current that becomes a certain amount of limit of a series of processing (such as rectification, shunting, dividing potential drop etc.) and measure.
Gauge outfit is used for the display measurement result.
The maintenance personal uses existing multimeter, when watching gauge outfit, owing to needing closer gauge outfit, often understands neck pain.In addition, the maintenance personal need to take pictures to collect data together to the position of test pencil measurement and the measurement result of gauge outfit when analyzing, because the volume of multimeter itself is larger, the scope of taking pictures is larger, and the effect that often causes taking pictures is bad, thereby has affected the quality of analysis report.
In view of this, the invention provides a kind of multimeter, this multimeter is set up a small display at test pencil, small volume, thus be conducive to improve the effect of taking pictures, in addition, also be convenient for people to watch the data that record.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of multimeter, and this multimeter is set up a small display at test pencil, small volume, thus be conducive to improve the effect of taking pictures, in addition, also be convenient for people to watch the data that record.
The object of the present invention is to provide a kind of multimeter, described multimeter comprises: a multimeter body and two test pencils, described multimeter body has a gauge outfit, a measuring circuit and two test pencil sockets, it is characterized in that, described multimeter also comprises a small display, described small display is fixedly arranged on the test pencil in described two test pencils, be provided with a small display line interface on the described multimeter body, it links to each other with described measuring circuit, and described small display line interface is used for being electrically connected described small display to show the measurement result of described measuring circuit output.
Preferably, the test pencil circuit of the test pencil that is fixedly held to of the circuit of described small display and described small display is integrated in one.
Preferably, described small display line interface is integrated in the corresponding test pencil socket of test pencil that described small display is fixedly held to.
Preferably, the circuit of described small display is independent of the test pencil circuit of the test pencil that described small display is fixedly held to.
Preferably, described small display line interface is independent of the test pencil socket on the described multimeter body.
Compared to prior art, multimeter of the present invention is by setting up the small display of a small volume at a test pencil, thereby is conducive to improve the effect of taking pictures, and in addition, also is convenient for people to watch the data that record.
For making purpose of the present invention, structural attitude and function thereof there are further understanding, hereby cooperate diagram to be described in detail as follows:
[description of drawings]
Fig. 1 is the block diagram of a preferred embodiment of multimeter of the present invention.
Fig. 2 is the structural representation of middle test pencil embodiment illustrated in fig. 1 and small display.
[embodiment]
Seeing also Fig. 1 and Fig. 2, is the schematic diagram of a preferred embodiment of multimeter of the present invention.Multimeter of the present invention comprises: multimeter body 10, test pencil 20 and small display 30.Wherein, multimeter body 10 comprises: measuring circuit 11, gauge outfit 12 and test pencil socket 13 have comprised test pencil line interface 131 and small display line interface 132 in the test pencil socket 13.
When using multimeter, test pencil 20 is plugged in the test pencil socket 13 on the multimeter body 10, at this moment, test pencil circuit 221 and small display circuit 31 are electrically connected to respectively test pencil line interface 131 and small display line interface 132, and test pencil 20 and small display 30 have all entered quasi-operating status.During measurement, the measurement result that test pencil 20 records reaches measuring circuit 11 via test pencil nib 21, test pencil circuit 221, test pencil line interface 131 successively, after 11 pairs of measurement results of measuring circuit are carried out respective handling, again measurement result is reached on the gauge outfit 12 and shown, simultaneously, measuring circuit 11 also reaches measurement result small display line interface 132, reaches on the small display 30 via small display circuit 31 to be shown again.In addition, when doing analysis report, only need to take pictures to the test pencil 20 measured and small display 30 get final product, owing to small display 30 volume ratio multimeter bodies 10 are little, thereby has improved the effect of taking pictures, and has improved the quality of analysis report.
During implementation, the small display circuit 31 of small display 30 can also be designed to be independent of the form of the test pencil handwriting 22 of test pencil 20, and simultaneously, small display line interface 132 also needs correspondingly to be independent of test pencil socket 13.
Certainly, embodiment described herein is many preferred embodiments that utilize in the embodiments of the invention, and sets forth by the mode of explanation rather than restriction here.It will be apparent to one skilled in the art that it should be apparent that, do not break away from itself under the prerequisite of the spirit and scope of the invention that appended claims limits, can make many other embodiment.
