Description
Technical field
The utility model belongs to electricity field, relates to a kind of debugging instrument, relates to a kind of Multifunctional debugging instrument particularly.
Background technology
At present, electronic technology is flourish, numerous electronics and Utilities Electric Co. fall over each other to occur like the mushrooms after rain, the application of various testing apparatus is more and more extensive, but most testing apparatus only has simple function, as reometer can only survey electric current, multimeter can not survey electric current, and stabilized voltage supply volume is large and can not survey electric current and voltage etc.; Carry multiple equipment very inconvenient simultaneously, and easily cause experiment table top to interlock Ling Pin when using multiple testing apparatus to test, make easily to make mistakes during Electronic Testing, conventional efficient is low, and experimental error is large.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of Multifunctional debugging instrument, reduces instrument when testing and takies experiment table area, improve experimental precision, convenient operation, meet the object of number of different types experiment demand.
The technical scheme that the utility model adopts is: a kind of Multifunction debugging instrument, the reometer comprise rectifying and wave-filtering bridge, being connect by the first power module and rectifying and wave-filtering bridging, the voltage table connect by second source module and rectifying and wave-filtering bridging and the regulated voltage level connect with rectifying and wave-filtering bridging.
Described regulated voltage level comprises the 3rd power module exporting 24V voltage, the regulator block 7805 exporting 5V voltage, the regulator block 7812 exporting 12V voltage and switch; Described 3rd power module one end and described rectifying and wave-filtering bridging connect, and the other end is connected with regulator block 7805 and regulator block 7812, and described switch is connected with the 3rd power module, regulator block 7805 and regulator block 7812 respectively.
Described regulated voltage level also comprises protection circuit.
The utility model beneficial effect is: user can use the level voltage of this instrument small area analysis of measuring voltage, electric current and 5V, 12V, 24V easily; Reduce instrument when testing and take experiment table area, improve experimental precision, convenient operation, meet number of different types experiment demand.
Accompanying drawing explanation
Fig. 1 is the utility model circuit principle structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of Multifunction debugging instrument, the reometer comprise rectifying and wave-filtering bridge, being connect by the first power module and rectifying and wave-filtering bridging, the voltage table connect by second source module and rectifying and wave-filtering bridging and the regulated voltage level connect with rectifying and wave-filtering bridging.Described regulated voltage level comprises the 3rd power module exporting 24V voltage, the regulator block 7805 exporting 5V voltage, the regulator block 7812 exporting 12V voltage and switch; Described 3rd power module one end and described rectifying and wave-filtering bridging connect, and the other end is connected with regulator block 7805 and regulator block 7812, and described switch is connected with the 3rd power module, regulator block 7805 and regulator block 7812 respectively.Regulated voltage level also comprises protection circuit.
During specific experiment, during utility model works, the alternating voltage of 220V is dropped to desirable value by transformer, by rectifying and wave-filtering, alternating current is converted to direct current, then the electric current after rectifying and wave-filtering is flowed to adjustable regulated voltage level power supply, reometer and voltage table respectively.Voltage table of the present utility model cannot can not measure superly voltage under DC200V very easily; Reometer coordinates 100A/75mv sample resistance R, can measure 100A DC current; 5V capacitor filtering and voltage stabilizing after regulator block 7805 step-down obtain, and 12V is through regulator block 7812.When surveying electric current, the terminal will surveying current circuit is received on the binding post of reometer of the present utility model, wherein red binding post connects positive pole, and black binding post connects negative pole, the reometer on panel just can display circuit actual current and side big current time must screw binding post.When surveying voltage by voltage table penholder at gaging hole, another termination will survey the end points of voltage circuit, can voltage table display DC voltage numerical value on Multifunctional debugging instrument panel.When needing stable level voltage, switch is screwed into tram, selects level voltage 5V, 12V or 24V of exporting.
