A Guide to Common Multimeter Symbols

Just like other tools, multimeters also have electronic symbols. Their means is important for proper understanding and use of the product. Whether you are still learning to use the device or you already have one for a while, breaking uncertainties on what a couple of the symbols really mean should be given attention.

Lots of different multimeters are sold everywhere. But all of them used common symbols. This article will guide you to common multimeter symbols while helping you how to choose the right multimeter in the right way.

AC VOLTAGE SYMBOL – AC voltage is the most common setting for testing voltages in the house or industry use. Voltage measurement usually falls between 100-240 volts AC. However, the measurement usually varies on the area where you live.

DC VOLTAGE SYMBOL – DC voltage enables users to test small electronic circuits, batteries and indicator lights. DC voltage usually measures 30 volts DC and just like AC voltage, you can find this thing with V symbol.

HOLD BUTTON – The hold button from the words itself holds whatever the device reads after it was pressed. This symbol has always been a great feature especially for users who want the exact reading always be remembered.

RANGE BUTTON – A button of multimeter device that is used to cycle between different ranges is the range button. Though most meters are equipped with the auto ranging feature but some devices have the option of selecting a specific range that user may opt for.

DIODE CHECK – This setting is considered to be the most reliable way to test and know if you’re using diodes that are bad or good enough. The diode test can also be used to check if a diode is functioning or not. When it comes to performing the test, the process usually involves using Ohms setting.

OHMS SETTING – Ohms setting is designed to measure resistance. Ohms setting does not just measure resistance but it can also be used to test the condition of fuses in a quick and easy way. When you test a fuse and the result is read as OL then you probably got a fuse that has blown.

CONTINUITY CHECK – Some people may find this symbol to be very familiar with a horizontal Wi-Fi symbol. Having this feature enables the meter to emit an audible tone when it is detected. If you’re finding short circuits or open circuits, the continuity can work fast and effective in any way. If there is an electrical connection between the probe tips, the multimeter produces sound. The continuity check can also be used to cooperate with other features of the device.

ALTERNATING CURRENT TEST – The alternating current is normally used with the addition of a clamp attachment. The alternating current of a multimeter is essential for testing. Let’s say for example you want to know how much load an appliance is representing, you can use the alternating current test to find it out.

BRIGHTNESS BUTTON – With the brightness button, you can change the backlight of the display probably from dim to bright. This multimeter button will help users change the brightness of the device during the day, night or anytime they want.

Other Tools and Symbols

S-SHAPED CURVED LINE – A curved line usually appear on your multimeter device and it usually shows with either V or A symbols together with their respective metric prefixes. That curved line stands for an alternating current and if it appears with V, it signifies that the voltage can be measured in an AC. If the curved line is placed with V, it means that you can measure the amps in an AC circuit.

PROBES – Probes are typically color-coded: color red for the positive and black for negative. Probes usually have a long exposed metal to make bare wire or component leads to be secured by twisting or with the use of alligator clips. This will make readings hands-free. Most basic probes have metal needles that can be used to touch wires and other components on a printed circuit board.

Symbols can easily be seen on your multimeter and it is easy to get confused on them as well. Some tools are discussed above and a few other parts, tools and symbols will further be discussed by www.zoniv.com. Take a look at them and find reasons why learning them is really important.
