The Best Multimeter Features

Graphic Function

The best quality multimeters have graphic functions which display AC measurements in real time. If you notice irregularities, this feature will come in handy to help you easily detect any fault with your appliances. It is even more useful to those who work with nonlinear AC waveforms.

Data Logging

This is another excellent feature that enables you to monitor and record your measured data over a long period of time. The software can record data over a prolonged period and also show the general trends within that period. After the data is collected, it can then be utilized for further analysis. This feature is much needed for the repair and installation of systems such as air conditioning and ventilation systems.

Low Pass Filter

If you want to troubleshoot motor drives, this feature will be perfect. Most of the RMS used may not have this feature but the best quality models will not let you down.  The low pass feature is meant to prevent unwanted voltages when measuring voltages that are higher than 1 KHz if measuring AC frequency or AC voltage.  It will also improve the level of accuracy when measuring voltages and current on appliances such as inverters and frequency motor drives.

Low Impedance Mode

This feature is necessary for preventing induced voltages from measurement. The voltage can result from capacitive coupling between energized wires. If the induced voltages are noticed, it can lead to more accurate measurements.

Smart Ohm

This is an advanced feature of the multimeter, and it’s available in a few different types of multimeter. It is also known as offset compensation, the feature that allows you to achieve greater measurement accuracy in some situations. This feature is needed when testing resistance with two distinct test currents to find out if there are offset voltages present in the input circuit.  With this check, it displays a corrected measure and eliminates any unexpected DC voltage within the circuit.

Voltage Tests

Voltage test is the most common feature of the multimeter. Almost all types of multimeters (whether digital or analogue) have this capability. The voltage test begins at the highest range and moves down to the most ideal voltage range for the appliance you intend to measure. However, if you want to measure voltages at different locations within the circuit you need to make use of the test leads to identify and effectively read the voltage differences. When measuring, remember that DC modes and AC modes are not compatible. Another important thing you need to know is to always measure your voltage first in order to find out if the circuit is DC or AC.

Measuring Ohms

Finally, a multimeter will not serve its rightful purpose if it is not able to measure ohms. It is the most important feature of the multimeter. The measuring ohm is required when checking for consistency of current on an appliance or a circuit. If a switch is open or a wire is broken, you may not be able to detect the fault until you make use of this feature. The ohmmeter will help you check for consistency when troubleshooting your device.   Although you can test for continuity using another method since some multimeters have a different feature that only test for continuity, those multimeters that can read both continuity and ohms are more preferred since they can also be used to test network and SCSI terminations.

Basic Uses of the multimeter

The multimeter is an integral part of any electrician’s working tool.

Without the multimeter, no meaningful troubleshooting task can be carried out. To a professional, using a multimeter may not be a big ask. However, a home owner or an individual who is not technically savvy will need to understand the basic functions of the multimeter before making effective use of the gadget.

Basically, a multimeter is used to measure AC/DC voltage, current, resistance, continuity and for diode checking purposes. Apart from knowing the functionalities of this gadget, it’s wise to understand its safety measures in order to remain safe when working with the multimeter.

This article will provide a detailed explanation of the various uses of the multimeter and some safety measures to make sure you remain safe when troubleshooting electrical appliances with the multimeter.



Uses of the multimeter

Measurement of AC/DC voltage

One of the primary things to do with a multimeter is to measure AC/DC voltage. When choosing a multimeter, it is necessary to select one with higher main voltage rating than traditional multimeters. It should be higher than most household voltage ratings, which is below 10 percent of 230 V. With the right kind of multimeter, you will able to accurately measure the AC/DC voltage of your electrical appliances to detect any issue with the appliance.

Measurement of AC/DC current

The same method of measuring voltage is also applied when measuring current. However, when measuring current it is important to adhere to safety rules. High current can result to electrical hazards which may be escalated by the use of cheap multimeters. This is the reason why you need to select the most ideal multimeter that will provide accurate and safety readings when troubleshooting your appliances.

Never make use of the multimeter above the range it was intended for.

This may lead to frequent cases of electrical hazards.

With the correct use of the multimeter and if the right safety measures are followed, the multimeter will definitely help you solve most of your electrical troubleshooting problems.

Measurement of resistance and continuity

This is another important feature of the multimeter. When measuring resistance between two points, it is done by moving current through the present component being measured. To do this effectively, you need to remove the component from the circuit. Closed circuits usually have a little resistance while open circuits have infinite resistance. All these will be familiar to you if you are an experienced electrician. However, if you are not so tech-savvy, you need to understand their differences to be able to do a better job when using the multimeter. Most multimeters are designed with a beeper which indicates the measurement of the small resistance through an emitted tone. Some are even designed with a visual alert, particularly a red light, to help users correctly detect the signals. When selecting a multimeter, choose a device with a good indicating light and tone that doesn’t delay when giving signals. This is why it is important to opt for a high quality multimeter because your work will be more effective if you are making use of the right piece of equipment.

Diode Checking

There are good multimeters with special features that can enable you perform diode checking on your appliance. This features show the forward voltage drop of the diode. When buying a multimeter, even when you only intend using it for household appliance, it is important to select a product which is diode checking enabled because you never know when you may need such features for your troubleshooting tasks.

Capacitance measurement

There are also some digital multimeters that can equally measure capacitance. But the digital multimeters measure capacitance in different ways than the handheld multimeter. The former makes use of AC signal which is more accurate than computing the voltage rate of change, used by the handheld multimeter. However, this measurement is not accurate when you want to measure capacitors with traits like equivalent series resistance, dissipation factor, leakage or dielectric absorption. In this case, a LCR meter should be pressed into action instead.

Frequency Measurement

Finally, a multimeter is also used for measuring frequency. This can be important if your appliance depends on a steady current and AC voltage for proper performance. You can monitor current or real time voltage with the frequency measurement within a specific pulse width, duty cycle or frequency. However, remember that not every multimeter is designed with this feature. It is always important to see what features the multimeter has before purchasing.
