Choosing The Best Multimeter

The Best Multimeter In Murrieta!

Choosing The Best Multimeter

A multimeter is also great for some basic sanity checks and troubleshooting. If your eyes can’t see it, the multimeter is usually a great second testing resource. The components and PCB traces inside the test meter are designed to take different amounts of current.

The multimeter is your first defense when troubleshooting a system. One of the most common mistakes with a new test meter is to measure current on a breadboard by probing from VCC to GND.A digital multimeter is an essential tool in every electronic enthusiast’s arsenal.A multimeter is a combination of a multirange DC voltmeter, multirange AC voltmeter, multirange ammeter, and multi-range ohmmeter.

What is a Multimeter? Where to Use It and When

What is a Multimeter?

A multimeter or Volt-Ohm meter, is a device used to measure voltage, current and resistance. Multimeter might be analog type multimeters or digital multimeters, depending on the type of circuit being used. Normally, these hand-held devices are very useful to detect faults or provide field measurements at a high degree of accuracy. They are one of the preferred tools by electricians to troubleshoot electrical problems on motors, appliances, circuit, power supplies, and wiring systems.

Analog multimeters are becoming obsolete as they are being replaced by digital multimeters.

Analog Multimeters

Analog multimeter is based on a micro ammeter that moves over a scale. Analog multimeters although cheap, can be very difficult to read accurately, and they must be handled carefully, because of you drop the meter, you are likely to damage it.

Digital Multimeters

Digital multimeters are designed for electronics engineers, so many multimeters, might contain features that probably you will not need ever. Digital meters will provide their output on a LCD screen, and might cost more than analog multimeters. Read more here.

The meter movement in a moving pointer analog multimeter is practically always a moving-coil galvanometer of the d’Arsonval type, using either jeweled pivots or taut bands to support the moving coil.

How to use a Multimeter or Test Meter

Multimeters are very cheap to buy and are one of the most commonly used pieces of electronics test equipment. Although basic operational multimeter instruction may be given when the test meter is bought, details of how to use the multimeter to test circuits and gain the maximum use from them are not always available.

When using the meter it is possible to follow a number of simple steps:

  1. Turn the meter on
  2. Insert the probes into the correct connections – this is required because there may be a number of different connections that can be used.
  3. Set switch to the correct measurement type and range for the measurement to be made. When selecting the range, ensure that the maximum range is above that anticipated. The range on the DMM can then be reduced as necessary. However by selecting a range that is too high, it prevents the meter being overloaded. See more here.

A common error when operating a multimeter is to set the meter to measure resistance or current and then connect it directly to a low-impedance voltage source.

How to pick the right meter

In most cases, an apprentice only needs to use the two basic functions common to most meters; voltage and continuity. But as your experience in the trade grows, so to will the need to measure more and different things. Amperage readings become more useful in troubleshooting circuits. The need to read frequency (Hz) may arise.

The ability to record certain aspects (minimum, maximum and average) of a measurement may be very convenient. And considering the increase in harmonics in circuits today, true RMS capability is a feature than is almost required. You may also come across the need to measure temperature as well. If you consider the economy of purchasing the best meter you can afford at the start of your career, it becomes obvious that buying that low-end meter in the beginning is not cost-effective in the long run.

If you buy a plain, low-end meter, you will find you soon outgrow its usefulness. You need a meter to do more, so you ‘move up’, and spend more money. A couple years later, you’ve outgrown the second meter, and purchase a third one. By the time you obtain your journey-level certification, you’ve paid for three meters. Check full article here.

A Multimeter Is Highly Resistive

However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance. Batteries inside the test meter are used to provide a current for the resistance measurements. The standard and basic measurements performed by multimeter are the measurements of amps, volts, and ohms.

A multimeter is most advanced instruments that make use of modern Integrated circuits for making measurements. The two things you’ll probably test most often with a test meter are resistance and voltage. It is still necessary to have a good look at what is needed and what the real requirements for the multimeter are before buying one, call us here: (951) 805-1262.
