Abstract
A simple electric measuring device is provided with two test rods connected with a power supply through a conducting wire, an LED connected with the power supply in series is arranged on the conducting wire, and a capacitor and a buzzer which are in pair and connected in parallel are connected between the LED and the power supply in series. The measuring device can simply detect whether a circuit or an electric appliance is in a normal state or not and give acousto-optic indication. The use method of the measuring device is as follows: when the circuit, or the electric appliance under a normal state or not is detected, the two test rods are aimed at the circuit or the electric appliance to be tested, if the LED shines when being conducted and the buzzer sounds, the circuit, or the electric appliance is under a normal state and is not damaged, and otherwise, the electric appliance is damaged; and when the resistor is tested, the test rods are placed at two ends of the tested resistor, and the resistor value can be simply judged through the intensity of the light and the sound of the LED and the buzzer.
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
General electronic measuring device such as avometer etc. in the prior art, its weak point is: this table price is higher, just gets through disconnectedly etc. in the real family life with it, can not all be equipped with a this instrument in the every household, its troublesome poeration in addition, common people is difficult to grasp the method for using.
The utility model content
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of simple and easy electronic measuring device easy to use simple to operate.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of simple and easy electronic measuring device, it is provided with two prods 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 electric capacity parallel with one another and hummer also are connected in series between light emitting diode and power supply.
Further, light emitting diode is also connected with a protective resistance, 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 the quality and the measuring resistance of metering circuit, electrical equipment simply, and the acousto-optic indication.Its using method is, when slowdown monitoring circuit, when whether electrical equipment damages, only needs two prods are aimed at circuit-under-tests or electrical equipment, when light emitting diode is connected luminous and hummer sounding, then proves, damage as yet, otherwise the time represent that then electrical equipment has damaged; When measuring resistance, prod is placed the measured resistance two ends, the power of sending optoacoustic by light emitting diode and hummer is simply judged the size of resistance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
