Abstract
The utility model relates to an universal meter, comprising a meter head, a change-over switch, a meter pen selecting switch, a meter pen jack and a test meter pen, wherein the test meter pen chooses a corresponding shift via the selecting switch. By replacing the traditional plugging choice, the universal meter provides convenience for a user to use.
Description
Technical field
The utility model relates to a kind of multimeter, particularly a kind of multimeter of testing test pencil through the switch selection.
Background technology
Along with the fast development of electronic technology, multimeter has become one of indispensable surveying instrument of slip-stick artist, has experienced technical development for several times, from the pointer multimeter of very early time to present digimer, sensitivity, degree of accuracy, stability is increasingly high.The exploitation of novel multimeter and design also more and more receive the attention of relevant enterprise.
At present existing; Most popular is digimer, and typical configuration comprises gauge outfit, switch, internal measurement circuit and external test pen, and internal testing circuit and external survey test test pencil are selected configuration through several test chart penholder holes; But when generally using according to the different parameter values of test; Just need to select different measurement jacks, frequent plugs, and the convenience of use and life-span just receive certain restriction.
Summary of the invention
The actual technical matters to be solved of the utility model is how for the user a kind of multimeter easy to use to be provided.
The utility model provides a kind of multimeter; Comprise gauge outfit, switch, test pencil jack and test test pencil; Said gauge outfit below is a switch; Said test test pencil one end inserts in the said test pencil jack, and said switch bottom also is provided with and can supplies to test the test pencil SS that test pencil is selected corresponding gear.
The advantage of the utility model is, has reduced the plug number of times of test pencil, has increased the serviceable life of test pencil, has improved the ease for use of product, has reduced user's burden.
Description of drawings
Fig. 1 is the structural representation of a kind of multimeter of the utility model.
Fig. 2 is the utility model test test pencil synoptic diagram.
Embodiment
Please refer to Fig. 1, shown in Figure 2, said multimeter 10 comprises gauge outfit 11, switch 12, test pencil jack 13, test pencil SS 14 and test test pencil 20.The gauge outfit 11 on said multimeter 10 tops is used for display system and measures numerical value; Gauge outfit 11 belows are switch 12; Mark has several indication gears such as voltage gear, zero frequency span, interchange shelves, resistance grade all around, and the parameter of measuring as required during use is transferred on the corresponding gear.Said switch 12 bottoms are test pencil SS 14; And said test pencil SS 14 is a knob switch, comprises the ampere shelves all around, milliampere microampere shelves and voltage resistance shelves; Test pencil SS 14 the right are test pencil jack 13, comprise red test pencil and black meter pen jack.When the user used, the parameter of measuring was as required come selective switchgear 12 gears and test pencil SS 14 gears, and the said test test pencil 20 of the utility model is selected corresponding gear through test pencil SS 14; More particularly; Said test test pencil 20 (comprising two test pencils of a redness and black) end inserts test pencil jack 13, and the inner physical construction of passing through is connected with test pencil SS 14, after test pencil SS 14 is got to corresponding gear; Test test pencil 20 (red test test pencil) also promptly is connected to corresponding gear; As required content measurement is connected to red-black two test pencils on the interlock circuit then, carries out concrete measuring operation.
Specify the user below how at the different enterprising line operates of measurement project:
(1) measurement of AC and DC electric current
Select appropriate current to measure range according to the size of measuring electric current through switch, select corresponding red test pencil gear through the test pencil SS simultaneously, when measuring direct current; The high end of red test pencil touch voltage, the end that the black meter pen touch voltage is low, forward current flows into multimeter from red test pencil; Flow out from black meter pen again; When the size of current that will measure is unclear, measures with maximum range earlier, and then reduce accurately measurement of range gradually.
(2) measurement of AC and DC voltage
Red test pencil SS is got to " V/ Ω " shelves, selects suitable voltage to measure range according to the size of voltage through switch, the black meter pen contact circuit " " end, tested point in the red test pencil contact circuit.Be noted that especially and digital multimeter measure the frequency of alternating voltage very low (45～500Hz), high frequency voltage of signals amplitude should adopt ac millivoltmeter to measure.
(3) measurement of resistance
Red test pencil SS is got to " V/ Ω " shelves, selects suitable resistance measurement range according to the size of resistance through rotary switch, and red, black two test pencils are the contact resistance two ends respectively, and observed reading gets final product.Particularly, when measuring on the road resistance (resistance on circuit board), should be earlier the power remove of circuit, in order to avoid cause the reading shake.Forbid measuring curtage (particularly alternating current 220V voltage), otherwise damage multimeter easily with resistance grade.In addition, utilize resistance grade can also qualitatively judge the quality of electric capacity.Earlier with the short circuit of electric capacity the two poles of the earth.
Above character introduction and description of drawings; Simple declaration for the utility model; Be core concept and method, those skilled in the art will appreciate that all based on above-mentioned technological thought method in order better to understand the utility model; That makes quoting or improving, all within protection scope of the present invention.
