How to Use Oscilloscopes and Multimeters

As a professional dealing with electricity issues, two handy tools to help you wade through your job smoothly are an oscilloscope and multimeter. While a multimeter can solve a variety of your problems by its versatile nature making it capable of measuring currents, voltages, resistances and checking into the functioning of transistors and diodes, the former only measures voltage. However, oscilloscopes look into their area of task much more meticulously as they look into the changes of voltages with time. Such tools can be best bought from online stores like Conrad which have a large display of them and deal with top notch brands such as VOLTKRAFT, Fluke, Proxxon, Tektronix and the likes. Here is a quick guide on how to use each of these tools.

Using Oscilloscopes

In order to measure electronic waves or circuit with the help of oscilloscopes you require linking the ground connector of the test lead of the tool to one of the ground points of the circuit to be measured. The probe’s tip then needs to be touched upon the point in the circuit which you wish to test. For a Cathode Ray Oscilloscope you can use the scope for measuring the waveforms when the amplitude control and the timebase control are modified to obtain the square wave. For safety reasons it is advised not to make a direct connection between the electrical outlet and the probe.

Using Multimeters

For using a multimeter you first need to be familiar with the various parts that it possesses. This includes the dial, the pointer, arc shaped lines depicting the various ranges of maginitude, a knob, jacks or inserting test leads, fuse and battery compartments, test leads and a knob called Zero Adjustment. Since the multimeter can be used for measuring a number of things separate functions go for them. For instance, the Volt function is to be used for measuring voltage, the OHM function for resistance, the Amps function for measuring Amperes and so on.

How To Choose Between Oscilloscopes and Multimeters

If you are an engineer working in a firm or an electrician undergoing regular electrical machinery testing jobs, multimeters and oscilloscopes can come extremely handy in your professional overtures. While oscilloscopes measure wave lengths and voltages in great details, multimeters are capable of measuring a number of things such as resistance, current, voltage as well as proper functioning of transistors and diodes. But which one would be more suitable for your work and how to choose them? As a dealer of a wide gamut of electronic products of brands such as Proxxon, Hameg, Tektronix and the likes here are a few tips from Conrad to help you choose the right tool for your work.

Multimeter or Oscilloscope?

A multimeter can do a great job in testing and maintaining general and daily electrical appliances and circuits but cannot check complicated machinery controls or other electronic design works. Moreover, while the former can depict the average level of voltages, oscilloscopes have the capacity to detect signals, changes in voltages, type of waves, compare voltages and a lot more.

How to Choose a Multimeter

In order to choose a Multimeter you have to look into the operational area for the device, the measurement functions, features like Auto Ranging and Dialing, battery life, display options and test lead lengths.

How to Choose Oscilloscopes

As in choosing a multimeter, the first things to consider while choosing an oscilloscope is also the area where you will be using it, the number of signals to be measured, the highest frequency of the signals needed and the maximum and minimum ranges of amplitude. You also require taking into account factors like whether the signals will be viewed both in the time and the frequency domains and whether they will be single or repetitive shots. However, the most important consideration remains that of choosing the right bandwidth or the input signal’s frequency range that is capable of passing with the least amplitude dissipation through the front-end analog.
