Abstract
The utility model relates to an electric testing device, in particular to a storage universal test meter, comprising a CPU, a data sampling cell which is connected with the CPU, an A/D converting cell and a display screen cell. The utility model is characterized in that the utility model also comprises a button cell which is connected with the CPU and a storage cell which is used for storing tested data; and the display screen cell at least comprises an area which is used for displaying the tested data and an area which is used for displaying the storage data. The utility model has the advantages of storing the tested data and reading the storage data for processing, analyzing and comparing if necessary.
Description
Technical field
The utility model belongs to electronic measuring instrument, is specifically related to a kind of multimeter with memory function, can store measured data, and extracts the data of being stored when needed and handle, analyze or contrast.
Background technology
Existing multimeter can only be used for disposable reading, particularly at used existing multimeters such as trouble shooting equipment and instrument products, can only lean on experience and existing data to carry out the judgement of measurement data, could overhaul and be out of order, and without reserve, can only record with notes, after the disposable reading of data like this to engineering technical personnel, during repair apparatus instrument product bug, time-consuming length, workload is big, need a large amount of source book etc.
Summary of the invention
The technical problems to be solved in the utility model is, at the shortcoming on the above-mentioned prior art, provides a kind of multimeter with memory function, can store measured data, and extracts the data of being stored when needed and handle, analyze or contrast.
The multimeter of the utility model band memory function, comprise that CPU, the data sampling unit that is connected with described CPU, A/D converting unit and screen show the unit, it is characterized in that, also comprise push-button unit that is connected with described CPU and the storage unit that is used for storage of measurement data, described screen shows the unit and comprises that at least a zone that is used to show measurement data and one are used to show the zone of storing data.
In multimeter described in the utility model, described push-button unit comprises on ﹠ off switch, is used for current measurement data is deposited the storage key of described storage unit, the pick-up key that is used for institute's deposit data before storage unit is extracted and the clear key that is used for removing data that storage unit is stored.
Also comprise the mark key up and down that is used to serve as a mark at push-button unit described in the multimeter described in the utility model, and the key that is provided with that is used to be provided with mark.
Show the unit at screen described in the multimeter described in the utility model and adopt the LCD video data, be provided with a display line among the described LCD, wherein delegation is used to show measurement data, and another row is used for showing the storage data.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the circuit theory diagrams of Storage universal test meter of the present utility model;
Fig. 2 is the panel synoptic diagram of Storage universal test meter of the present utility model.
Embodiment
Be illustrated in figure 1 as the circuit theory diagrams of Storage universal test meter of the present utility model, as can be seen from the figure, the technical data of equipment under test instrument product is passed through sampling unit, through the A/D conversion, handling screen by CPU shows the unit and shows and read, as think normally one group of data accurately, by storage and in storage one side of display screen demonstration, and measure another similar equipment under test instrument product technology data through above-mentioned transmittance process, compare in the display unit demonstration to be measured of display screen and with storage one side's data presented, thereby the technology of judgement equipment under test instrument product refers to the quality of skill.
Be illustrated in figure 2 as the panel structure chart of Storage universal test meter of the present utility model, as can be seen from the figure, the technical data of equipment under test instrument product is such as the DC voltage that is each point, press on ﹠ off switch 2, the universal seclector 7 of Storage universal test meter to DC voltage is kept off, by the COM9 of multimeter, the VOHM8 end is by key 3 is set, is each point 1 in order by mark key 6 up and down again, 2,3,4 ... Deng serving as a mark, and mark mark 1,2,3,4 ... storage and to-be-measured cell at display screen are by the intrinsic demonstration of software; And measure DC voltage in order one by one, as showing: 1 12.0,2 11.5,3 5.0,48.0 ... v etc., normal in this way one group of measurement data, one by one by storage key 1, this group measurement data can be automatically shows in the storage unit of display screen one by one, and as standard; Measure the DC voltage of each identical point of another similar equipment under test instrument product then and measure one by one in order, as showing: 112.1,2 11.5,3 5.2,4 8.1 ... v etc., and show at the display unit to be measured of display screen one by one; Too much as one group of measurement data, press front and back pick-up key 5, and contrast one by one, thereby whether each point of judging equipment under test instrument product is normal with the storage unit data presented; Finish as measurement, do not need this group measurement data, press clear key 4, remove this group measurement data.As measure the DC current of each point, and the COM9 by multimeter then, mA11 end or A10 end, and measure each DC current.This brings great convenience for the maintenance engineering technician, promptly saves time, laborsaving, convenient and swift again.
