• What is the Use of DigitMultimeter?

• Also known as Digital Multimeter, it evolved
  from AVOmeter in the 1920s. Since it was used to
  measure amps, volts, and ohms, it was named
  an AVOmeter. You can find the analog versions of
  this original equipment still, the modern version
  of it is a digital multimeter. It is more common
  and has various functionalities.

• This equipment is no longer confined to the
  measurement of resistance, current, or voltage.
  One can use it to test for continuity in a
  circuit. Some models can measure capacitance
  also. They are very much useful in Engineering
  Colleges or Indian railways where they need to
  measure capacitance quite often. Most of the
  models can test diodes, transistors, and
  batteries as well. They can distinguish between
  AC and DC currents.

• What is Digital Multimeter?

• Analog and digital multimeters have a big
  difference. Though Scientific
• Suppliers supply both types of equipment, digital
  is more used nowadays.
• In an analog machine, the needle is moved by
  electromagnetic induction. On the
• other hand, in a digital multimeter, there is an
  electronic circuit, which is more
• sensitive to very minute impulses also.

• Reading a digital multimeter using a LED
  display is always more reliable than gauging the
  position of the needle on a dial.  Every
  multimeter can measure ohms, amps, and volts.
  They have a dial that allows you to adjust the
  sensitivity. On the dial, there are DC voltage
  settings for 200 millivolts to 1000 volts. For AC
  current, it has voltage settings from 200
  millivolts to 750 volts.

• What are the Applications of a Multimeter?

• Anyone that works with electrical equipment
  needs a multimeter. Even, tradespeople like
  electricians and appliance repair professionals
  also use them regularly. Even daily household
  circuitry and other home appliances also need a
  multimeter to diagnose the problem.

• It can be used for testing voltage. We can
  measure the voltage across the circuit and
  voltage drop if any.

• It can be used for testing current. The mA
  scale is useful for that.

• It is used for testing resistance. There is a
  built-in power source that gets activated when
  the resistance scale is selected. It is also used
  for continuity testing.

• MEXTECH is one of the best companies for
  providing a wide range of test and measurement
  instruments in India. For over years they have
  been a leading manufacturing company specializing
  in digital multimeters, clamp meters,
  thermometers, Thermo hygrometers various other
  instruments.
