Abstract
The utility model provides a universal meter, which comprises a universal meter body and two meter pens. The universal meter body is provided with a meter head, a measuring circuit and two meter pen jackets. The universal meter is characterized by further comprising a small display screen which is fixedly arranged on one of the two meter pens. A small display screen circuit interface connected with the measuring circuit is arranged on the universal meter body and used for being electrically connected with the small display screen to display measurement results output by the measuring circuit. Shooting effect of the universal meter can be favorably improved by adding the small display screen with small volume to one meter pen. In addition, users can conveniently look over the measured data.
Description
[technical field]
The utility model relates to a kind of multimeter, relates in particular to a kind of multimeter that has 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 made up of gauge outfit, metering circuit, test pencil socket and switch etc.
Measuring circuit is to be used for the various measured circuit that are transformed into the small DC current that is fit to the gauge outfit measurement; It is formed it by resistance, semiconductor element and battery and can various measured (like electric current, voltage, resistance etc.), different range be sent into gauge outfit through the unified small DC current that becomes a certain amount of limit of a series of processing (like rectification, shunting, dividing potential drop etc.) and measure.
Gauge outfit is used to show measurement result.
The maintenance personal uses existing multimeter, when watching gauge outfit, owing to need closer gauge outfit, through regular meeting's neck pain.In addition, the maintenance personal need take pictures together to the measurement result of test pencil sites measured and gauge outfit and collect data when analyzing; Because the volume of multimeter itself is bigger; The scope of taking pictures is bigger, and the effect that often causes taking pictures is bad, thereby has influenced the quality of analysis report.
In view of this, the utility model provides a kind of multimeter, and this multimeter is set up a small display on test pencil, and volume is less, thereby helps improving the effect of taking pictures, and in addition, also is convenient for people to watch the data that record.
[summary of the invention]
The fundamental purpose of the utility model is to provide a kind of multimeter, and this multimeter is set up a small display on test pencil, and volume is less, thereby helps improving the effect of taking pictures, and in addition, also is convenient for people to watch the data that record.
The purpose of the utility model is to provide a kind of multimeter; Said multimeter comprises: a multimeter body and two test pencils; Said multimeter body has a gauge outfit, a measuring circuit and two test pencil sockets, it is characterized in that said multimeter also comprises a small display; Said small display is fixedly arranged on the test pencil in said two test pencils; Said multimeter body is provided with a small display line interface, and it links to each other with said measuring circuit, and said small display line interface is used to electrically connect said small display to show the measurement result of said measuring circuit output.
Preferably, the test pencil circuit of the test pencil that is fixedly held to of the circuit of said small display and said small display is integrated in one.
Preferably, said small display line interface is integrated in the pairing test pencil socket of test pencil that said small display is fixedly held to.
Preferably, the circuit of said small display is independent of the test pencil circuit of the test pencil that said small display is fixedly held to.
Preferably, said small display line interface is independent of the test pencil socket on the said multimeter body.
Compared to prior art, the utility model multimeter is through setting up the less small display of a volume on a test pencil, thereby helps improving the effect of taking pictures, and in addition, also is convenient for people to watch the data that record.
For making purpose, structural attitude and function thereof that further understanding arranged, cooperate diagram to specify as follows now to the utility model:
[description of drawings]
Fig. 1 is the block diagram of a preferred embodiment of the utility model multimeter.
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 synoptic diagram of a preferred embodiment of the utility model multimeter.The utility model multimeter 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 is electrically connected to test pencil line interface 131 and small display line interface 132 respectively with small display circuit 31, and test pencil 20 has all got into quasi-operating status with small display 30.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 handled, measurement result is reached on the gauge outfit 12 show again, simultaneously; Measuring circuit 11 also reaches small display line interface 132 with measurement result, reaches on the small display 30 via small display circuit 31 to show again.In addition, when doing analysis report, only need take pictures with small display 30 to the test pencil of measuring 20 gets final product, because 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 practical 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 need correspondingly be independent of test pencil socket 13.
Certainly, the embodiment that has described here is the preferred embodiment among many embodiment that utilize the utility model, and sets forth through 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 utility model spirit that appended claims limits and scope, can make many other embodiment.
