Abstract
The utility model discloses a simple electronic measuring device; the device is provided with two testing terminals which are connected with a power supply by a wire; the wire is provided with a light-emitting diode which is connected in series with the power supply; a pair of buzzers and a pair of capacitors which are mutually connected in parallel are connected in series between the light-emitting diode and the power supply. The measuring device has simple structure, low manufacturing cost, not only can simply measure the switching of a circuit and gives out sound and light indication but also can simply judge the resistance.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of simple and easy electronic measuring device.
Background technology
At present, people often use multimeter etc. to general electronic surveying, its weak point is: this table price is higher, in the reality family life also just be at most get through with it disconnected etc., can not all be equipped with a this instrument in the every household, its troublesome poeration in addition, common people is difficult for grasping the method that instrument is used.
The utility model content
At above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of simple and easy electronic measuring device.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of simple and easy electronic measuring device, it is provided with two test leads that join by lead and power supply, be provided with on lead and the power supply light emitting diode that is connected in series, a pair of hummer parallel with one another and electric capacity also are connected in series between light emitting diode and power supply.
As preferably, described power supply is also connected with a variable resistor, in case when measuring because the excessive damage light emitting diode of electric current.
Compared with prior art, advantage of the present utility model is: this measurement mechanism is simple in structure, cost of manufacture is low, and not only the break-make of metering circuit reaches and the acousto-optic indication simply, and can also simply judge the size of resistance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, simple and easy electronic measuring device of the present utility model, it is provided with two test leads 1 that join by lead and power supply 5, on lead, be provided with and power supply 5 light emitting diode 2 that is connected in series, also be connected in series between light emitting diode 2 and power supply 5 a pair of hummer parallel with one another 3 and electric capacity 4, described power supply 5 is also connected with a variable resistor 6.
In the use,, only need two test leads 1 are aimed at circuit-under-test or electrical equipment, when light emitting diode 2 is connected luminous and hummer 3 sounding, then prove, damage as yet when slowdown monitoring circuit, when whether electrical equipment damages, on the contrary the time represent that then electrical equipment has damaged; When measuring resistance, test lead 1 is placed the measured resistance two ends, the power of sending optoacoustic by light emitting diode 2 and hummer 3 is simply judged the size of resistance.
