INSTRUMENTOS DE MEDIDA
A multímetro or tester is a measurement instrument offers the possibility of measuring different electrical parameters or magnitudes in him himself apparatus. The used instruments of measurement but are the voltmeter, ammeter and ohmetro, which is the used ones frequently in all the range of electronics and electricity. Models from multimeters exist different which are: among which they can must have three basic functions of an apparatus which are: A resistance tester, that emits a sound when the circuit under test is not interrupted or the resistance does not surpass a certain level. (Also it can show in screen 00,0, depending the type and model). Presentation of results by means of digits in a screen, instead of reading in one climbs. Amplifier to increase sensitivity, for the measurement of tensions or currents very small or resistance of very high value. Measurement of inductancias and capacitances. Tester of diodes and transistors. Scales and socles for the measurement of temperature by means of standardized thermocouples. There are two types of multimeter which are: Analogical Multimetro: these but are used and the easy ones to use. / Multimetro with functions outposts: these are but difficult to use since they have functions but outposts and that are very common to us. /Note: /An oscilloscope is an electronic measuring instrument for the graphical representation of electrical signals that they can vary in the time. Very it is used in signal electronics, frequently next to a phantom analyzer. It presents/displays the values of the electrical signals in form of coordinates in a screen, in which normally x-axis (horizontal) represents times and the axis and (vertical) represents tensions. The image thus obtained denominates oscilograma. Usually they include another entrance, call “z-axis” that controls the luminosity of the beam, allowing to emphasize or to extinguish some segments of the plan. The oscilloscopes, classified according to their internal operation, can as much be analogical as digital, being the result shown identical in either cases, in theory.
