The meter is a measuring instrument also well-known names: VOM (Volts, Ohms, Milliammeter), Tester, tester.
Currently there multimeters capable of measuring many other quantities. (Capacitance, frequency, temperature, etc.)..
This measuring instrument for its price and its accuracy is still the favorite of amateur and professional electronics.
Other instruments such as oscilloscope that has a higher price and is used to make measurements more informative.
There are two types of multimeters: The analog meter and the digital multimeter. View: Analog and Digital.
analog multimeters
analog multimeters are easily identified by a needle that moves over a scale indicates the value of the measured quantity.
Digital multimeters
The DMM are identified primarily by a number pad to read the measured values, the absence of the common scale is the analog mulímetros . See graph at right.
What we do have is a function selector and range switch (some have no range switch as the VOM automatically determined). Some have a single central switch.
The function selector used to choose the type of measurement to be performed. See the chart below as locating the selector functions for measuring voltage AC and DC, AC , DC and resistance.
selector ranges multimeter is used to set the maximum value that can be displayed.
If you have an idea of \u200b\u200bthe magnitude to begin measuring the largest range.
This prevents damage or deterioration of multimeter. See some examples in the table on the right. See
that always choose a higher rank than the magnitude being measured.
