If you are trying to learn electronics repair, you need to get acquainted with these basic tools and you may need to go buy them for your self. If not now, you certainly will need to get your own tools at some point in time.
I am not telling you go out there and start shopping around for professional tools and equipment but if you are serious about becoming a plasma and LCD TV repair technician, you will most definitely need the most basic of tools right at your disposal.
The Multimeter
As the name implies, this device is a measuring device that measures more than one variable or parameter. This is a very essential tool in a TV repair man's tool box because it is one of the most basic tools to use in electronic fault-finding. Wikipedia describes the multimeter as an “electronic measuring instrument that combines several measurement functions in one unit.”As a matter of fact, aside from taking circuit continuity tests most modern multimeters has the capability measuring current (amperes), checking resistance (ohms) and testing voltage levels (volts). There are even other models that could test capacitors, diodes and transistors.
There are two types of multimeters: analog and digital.
If you are getting one, I would recommend getting the digital multimeter as it is generally more accurate compared to its analog counterpart. Some digital multimeters are so packed with features (most of which you are not likely to need).
Below are other parameters that modern multimeters can read (source: Wikipedia: Multimeter):
Parameters measured by a typical multimeter:
- Voltage in volts.
- Current in amperes.
- Resistance in ohms.
Other multimeters may also measure:
- Capacitance in farads.
- Conductance in siemens.
- Decibels.
- Duty cycle as a percentage.
- Frequency in hertz
- Inductance in henrys
- Temperature in degrees Celsius or Fahrenheit.
Digital multimeters may also include provisions for:
- Continuity that beeps when a circuit conducts.
- Diodes and Transistors
