Typically the DC voltage is marked as a V followed by a short line with a dotted line under it. The wavy … ", "This article helps me to understand how to read a multimeter. And even a cheap, category I (CAT-I) multimeter is fine as you are merely testing voltage, not amperage. Check the breaker of the branch circuit you are measuring voltage, is it on or off?When everything has been checked and everything is normal, maybe the Power Distribution Unit is switched off. Approved. This article was co-authored by Jesse Kuhlman. –You must break the circuit and place the meter in series with the circuit and/or component. If your multimeter has a power switch, is it on? For accurate readings, switch off the light sensor on your analog multimeter, once you connect the multimeter to the device under test, you will get your readings from the resistance ammeter. Analog Multimeter, Measuring Current Steps in using your meter to measure Current flow. Test AC or DC voltage. If you're having trouble remembering the difference between voltage and amperage, picture a water hose. In this way the optimum accuracy and significant number of figures can be read. Multiply the number scales that the pointer gave you with 5VAC. analog multimeter full image by Paul Moore from, Electronics and Radio Today: How to use a Multimeter, The Electricity Forum: Analog Multimeters. "I'm not very knowledgeable at all with electricity. Connecting the two leads to the positive and negative terminals of an electrical circuit and setting the range selector to the right setting will give an accurate readout of the current in the circuit. What can I do? Fortunately, it won't take long to translate the settings and understand how to read the scale, so you can get back to your work. Expert Interview. ", "Just bought an analog multimeter and this helped me know what it's trying to tell me, thank you! Connecting the two leads to the positive and negative terminals of an electrical circuit and setting the range selector to the right setting will give an accurate readout of the current in the circuit. \$\endgroup\$ – Bimpelrekkie Feb 9 '18 at 8:10 1 \$\begingroup\$ Sure, but you use the multimeter in … In many cases though, an analog multimeter lacks the power needed to test current. Jesse is also the author of four eBooks on home wiring including "Residential Electrical Troubleshooting" which covers basic electrical troubleshooting in residential homes. 3. Next, switch the range selector to the desired AC voltage range, i.e. Where do I put the multimeter when I am measuring amp? An analog multimeter generally consists of a screen with a pointer and multiple scales, a range selector and two leads. The biggest drawback to analog multimeters is that they can be difficult for beginners to read. Read the highest number when the range is set to 250 A, the middle number when at 25 A, and the lowest when at 2.5 A. Karl Wallulis has been writing since 2010. The Red Meter lead/Probe is Positive 2. The "DC" scale is for reading DC voltage. Master Electrician. This article was co-authored by Jesse Kuhlman. In order to get the best reading, it is necessary to have the scale reading somewhere between about a quarter and all of the FSD. This article has 12 testimonials from our readers, earning it our reader-approved status. While digital multimeters showcase a numeric display, analog multimeters provide readings through the use of a microammeter with a moving pointer. On the 200mA scale, you are displaying milliamps so, as you suggest, a current of 1A would be 'off the scale'. Electricity can be a complicated subject, and we understand how confusing it may sound when we talk about circuits, beakers, amps, and volts. This is the maximum that the range can read.

\n<\/p><\/div>"}. See the end of this section for a brief explanation. The meter movement is delicate and dropping the meter is likely to damage it! This will prevent an overcurrent from occurring, which could damage the multimeter. Have an idea how high the voltage you are going to measure will be, so that you can set the range selector to the proper voltage range. This article has been viewed 671,927 times. A typical multimeter can measure voltage, current, and resistance. Set the multimeter's zero position by touching the ends of the two probes together and pressing the zero position adjuster button just below the screen. If the needle of an analog multimeter points below zero even at the lowest range, then your "+" and "-" connectors are probably backwards. You could also just check … Circuits. Connect the negative probe to the common outlet on the multimeter. "Pictures are nice and clear. "It has helped me to understand and reading the tester meter, I just need to take a little more time with this. Nearly every analog multimeter has a dial to change the end voltage potential, from 30 volts for example to 0.01 Amps as well. Check the range setting that your analog multimeter’s dial is adjusted to. Select interchanging or direct current, depending on the type of circuit you’re working with. Measuring resistance on electronic components whether doing it individually or in-circuit, is not simple unless you had learned how to read resistance scale using an ohmmeter of an analog… Although this can be difficult at times, it is the best option. If you have a dedicated car battery test range, select the DC volts location on your multimeter (or the 12V setting). A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. Before you attach your multimeter to the circuit, you need to make sure that the meter is rated for the number of amps traveling through that circuit. The number that the needle stops on indicates the volts, ohms or amps the meter is measuring depending on how the control knob is set. Is it on the proper voltage range? Turn on the meter and insert the probes into the appropriate spots. It is primarily used to measure voltage (volts), current (amps) and resistance (ohms). By default, it should display the numeric result, but there could also be settings that display bar graphs or other forms of information display. Note that 5VAC per division will vary depending on the position of your range selector. Each range on the DC display is used for two positions of the selector switch. Check the position of the needle on the "DC A" scale of the screen display. This setting is to measure resistance. For tips on how to adjust for off the scale readings, keep reading! If you are reading 0.332 on the 2M setting, that would be 332K. Each type of meter has its advantages. If you want to test a DC circuit, switch the setting on your multimeter to VDC or DCV. If the needle hasn't moved significantly to the left, remove one of the probes and switch the range selector from 250 A to 25 A, and then from 25 to 2.5 A if necessary (not all multimeters have a 2.5 A setting). Last Updated: May 29, 2020 Analog multimeters are cheaper than digital… It was later developed and sold as the … We use cookies to make wikiHow great. This is the maximum that the range can read. To read a multimeter on an AC system, you'll need to locate the numbers and symbols on your circuit system. This article explains in detail how to read the current and voltage using the multiple scales on an analog multimeter or multitester (the kind with a pointer), not how to use a multimeter. Analog multimeters use a microammeter with a moving pointer to display readings. The line can appear next to or over the letter. So if I were to set the knob to 200 millivolts (0.2 volts), the 1.6 volts of the AA battery is too much for the multimeter to handle at that setting. Analog multimeters, like digital ones have a variety of ranges. Jesse Kuhlman is a Master Electrician and the Owner of Kuhlman Electrician Services based in Massachusetts. In order to get the best reading, it is necessary to have the scale reading somewhere between about a quarter and all of the FSD.
