How To Choose The Best Multimeter?

You might be aware of the fact that digital multimeters are devices that can be of great help in the work of electricians. These units are used for a number of activities right from installation to troubleshooting of electrical devices. As different models are available in the market, it is really hard to determine the unit that will be of the right choice. The decision should be made based on your application requirements, your budget and the frequency of using them. When you end up with a unit with limited features as compared to your application requirements, there is a higher risk of electrical hazards. So, careful selection is something highly important. choose from the best multimeters in 2017

What are the points to consider in the selection process?

When selecting a multimeter, you will have to consider different factors like accuracy, resolution and digits, input impedance and RMS converter. There are different units that can meet just fundamental requirements, while there are also units with some advanced features. Now, let us get into a basic review of some multimeters, and you can decide which fits for your needs:

Fluke 87-V:

This unit is certainly one of the best meters in the market. It is known for its reliability, stability and accuracy. It is a flagship model from Fluke brand and it is considered an industry leader and even when used frequently, the long lasting battery is something highly appreciated. Capability to measure temperature is one of the most important and beneficial feature of this unit. Even though it is not cheap, it will bring you what you pay for. With so many positive things about this unit suitable for an amateur, the negative thing about this model is its heavy weight.

Fluke 117:

Fluke 117 is a True RMS Multimeter is yet another member of the Fluke series of multimeters. The unique features of this model make it the best choice for demanding settings and buildings like schools and hospitals and other commercial settings. This unit encompasses non-contact voltage detection. This addition eliminates the need for secondary voltage detection tools. This feature-rich model has the excellent and worth-to-mention feature called VoltAlertTM, which is nothing but non-contact voltage detection. As against other high-end models from Fluke that are made in USA, this model is made from China. The negative thing about this unit is that it does not measure microamps and milliamps.

Fluke 116:

Fluke 116 is a model introduced by Fluke for HVAC/R application. This model has all other features similar to that of 117 other than the VoltAlert feature. Furthermore, it has the temperature measurement feature, which is not found in Fluke 117. In addition to HVAC, it can be used for troubleshooting problems with flame sensors. But for testing flame sensors, it just has microamps and does not have 10 amp input.

Fluke 115:

Fluke 115 was introduced by Fluke for Field service application. It does not measure temperature and ghost voltage detection is also not possible. But, AC/DC amps, frequency, capacitance and diode testing is possible with this unit. The attractive things of this model is the portability, accuracy, simplicity and the professionalism. The negative thing is that when reading low DC voltage, this unit does not display tenths of milli volts. It also lacks ability to read micro and milli amps.


So, if you are particular about selecting a Fluke brand multimeter, it is better to compare these models and arrive at the right choice as per your requirement. We thanks for the help of! This webpage collects the best multimeters in 2017 – and we highly recommend to visit it if you would like to know more about the best models on the market right now, and you can learn every details which will help you to choose the right model for your needs.

Do You Want To Test Computer Power Supply With Multimeter?

Summary: Sometimes need arises to check whether your PC gets the right power supply. This is possible with the help of a multimeter. Do you experience problems like sudden computer restarts or frequent crashes? When these things happen, most of us believe that our computer is affected by a virus or this might be the result of hardware failure. But, many of us forget to do one thing. Yes, we do not check the Power Supply Unit of the computer. A faulty power supply unit can be the trigger behind these crashes and restarts. The reason is that when the power supply unit is faulty, it will not supply the required voltage to the system, thereby leading to freezes or crashes. psu-and-multimeter-test

What does the power supply do?

The unit that provides energy to the computer is responsible for transforming the alternative current from the wall conduit into a straight power flow that can be used by the components of the computer. This is where a multimeter will help. This meter can be used for testing the power supply of the computer. Testing computer power supply with a multimeter will help with identifying and isolating any possible problems, and this unit will also help with identifying poor power supply. It is recommended to use the probes to get into contact with the terminals and the wires. It is better not to use fingers as there are chances of shocks. Otherwise, a binder clip or a stand can also be used for this purpose. Here is a step-by-step guide on testing computer power supply with multimeter: 1.    The first thing you will have to do is to test the surge protector and the outlet, where the current supply is attached. Now, shut down the computer and remove it from the surge guarding unit. Then, disconnect the guarding unit from the wall unit. 2.    Now, you will have to fix your digital multimeter so as to measure the AC voltage. Fix it to 200 V range and insert a probe into the one side of the outlet and the other on the right side. The color of the probe need not be considered as it is AC current. Now, you should be able to see the reading in the range of 110 and 120 volts. 3.    The next thing you will have to do is to connect the surge safeguarding unit into the vent such that surge protector can be tested. At this instance too the deciphering should be in the range of 110 and 120. 4.    Again, you should adjust your multimeter to test resistance, and your multimeter will produce a tone if there is stability along with a wire. Now, detach the cord that is attached to the energy supply on the rear side of the computer. Use one of the DMM Probes to get in contact with one of the plug terminals. Again, attach the other probe into the female end of the wire. In case you find that not even a single home produces a sound on your multimedia, it means that the cord should be restored. If you find that there is stability for each of the three wires in the supply cable, this means that there is a problem with the energy supply. So, follow these steps for test computer power supply with multimeter to secure your computer.
