Embodiment
Consult Fig. 1, Fig. 2, a kind of Electronics and Information Engineering multimeter shown in Fig. 3 and Fig. 4, comprise multimeter body 1, and the measurement index by-pass cock 2 be arranged on multimeter body 1, and the pointer indicator gauge 3 be arranged on multimeter body 1, and the digital display screen 4 be arranged on multimeter body 1, and the p-wire 5 be arranged on multimeter body 1, and the p-wire wind 6 be arranged on multimeter body 1, described p-wire 5 is connected to the bottom of multimeter body 1, described p-wire 5 is provided with test pen 7, described p-wire wind 6 is fixedly mounted in multimeter body 1, and p-wire 5 is connected with p-wire wind 6, described p-wire wind 5 is by threaded rod 8, winding disc 9 and fixed bar 10 form, described multimeter body 1 is provided with navigation button 11, a fixed head 12 is provided with in described multimeter body 1, described navigation button 11 is provided with backstay 13, described backstay 13 runs through fixed head 12, and match with fixed bar 10, described multimeter body 1 is provided with the draw-in groove 14 for fixing test pen 7.
Described winding disc 9 is arranged on threaded rod 8, described fixed bar 10 is arranged on winding disc 9, described threaded rod 8 is arranged with the back-moving spring 15 resetted for p-wire wind 6, described fixed head 12 is provided with a backhaul cylinder 16, and output terminal and the navigation button 11 of described backhaul cylinder 16 offset.
Described multimeter body 1 is provided with lighting device 17, and lighting device 17 is provided with two, and described lighting device 17 is LED.
Be enclosed with an antivibration pad 18 bottom described multimeter body 1, described antivibration pad 18 removably connects with multimeter body 1.
Described draw-in groove 14 is provided with two, and is symmetricly set on the both sides of multimeter body 1.
Further, what fill in backhaul cylinder is nitrogen, and nitrogen is the odorless nontoxic gas of a kind of colorless and odorless under normal condition.The chemical property of nitrogen is very stable, is difficult to react with other materials under normal temperature, and nitrogen is insoluble in water.Nitrogen accounts for 78.12% (volume fraction) of air total amount, is the Main Ingredients and Appearance of air.The aging of rubber is subject to caused by the oxygen molecule oxidation in air, its intensity and flexibility decrease after aging, and have crack performance; Compared with general high voltage air, high-purity nitrogen is because anaerobic and water content not oil-containing hardly, and its thermal expansivity is low, heat conductivity is low, heats up slow, reduces the speed of cylinder heat build-up, the characteristic such as non-combustible also not combustion-supporting, so can improve the stability of cylinder operation widely.
Multimeter is the most basic instrument in Electronic Testing field, is also that one uses testing tool widely.Multimeter is again multimeter, avometer (A, V, Ω is also electric current, voltage, resistance three with), multi-meter, universal meter, multimeter is divided into pointer multimeter and digital multimeter, also has a kind of oscillography multimeter with oscillograph function, is a kind of multi-functional, multiple range measurement instrument.General multimeter can measure DC current, DC voltage, alternating voltage, resistance and audio-frequency electric equality, some parameters can also surveying alternating current, electric capacity, inductance value, temperature and semiconductor (diode, triode) had.Digimer becomes main flow, replaces analogue instrument.Compared with analogue instrument, digital instrument is highly sensitive, and degree of accuracy is high, and it is clear to show, and overload capacity is strong, is easy to carry, uses also simply more convenient.
Multimeter not only can be used for measuring the resistance of object being measured, and combined-voltage can also measure DC voltage.The multimeter even had can also measure the major parameter of transistor and the electric capacity etc. of capacitor.The fully skilled using method grasping multimeter is one of most basic skills of electronic technology.Common multimeter has pointer multimeter and digimer.The multi-functional measurement instrument of pointer-type multimeter to be a gauge outfit be core component, measured value is indicated by meter pointer and reads.The measured value of digimer is directly shown in digital form by LCDs, and it is convenient to read, and some is also with sound prompt function.Multimeter is a public gauge outfit, and collecting voltage table, reometer and ohmmeter are in the instrument of one.
The DC current shelves of multimeter are multiple range D.C. voltmeters.Gauge outfit closed type divider resistance in parallel can expand its voltage range.The shelves of direct voltage of multimeter is multiple range D.C. voltmeter.Gauge outfit series connection divider resistance can expand its voltage range.Divider resistance is different, and corresponding range is also different.The gauge outfit of multimeter is magnetoelectricity series measuring mechanism, and it can only pass through direct current, utilizes diode that interchange is become direct current, thus realizes the measurement of alternating current.
The beneficial effect of a kind of Electronics and Information Engineering multimeter of the utility model is: during use, by set p-wire wind, when needs carry out voltage or testing current, test pen only need take off by user, and the p-wire that pulls outward, the length of p-wire is made to meet the length of user's needs test, and user presses navigation button simultaneously, the backstay be arranged on navigation button is matched with the fixed head be arranged on p-wire wind, thus play fixation, be convenient to the use in user's later stage, while user is pulled outwardly p-wire, the back-moving spring be set on threaded rod stores power, when user does not use, control backhaul cylinder, navigation button is resetted, backstay is pulled back, under the effect storing the good back-moving spring of power, p-wire wind is made to carry out the rotation contrary with the sense of rotation being pulled outwardly p-wire, thus automatically shrink p-wire.Its structure is simple, uses, easy for installation, simple to operate, and measure precisely, convenient reading, shock-proof effect is good, and cost is low, applied widely, long service life, has safe and reliable effect.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
