Meaning to say the How about the DB scale? Once the power to the circuit has been turned off, attach the red probe on the multimeter to the negative terminal of the power supply, and touch the black probes to the negative wire and turn on the circuit. Touch the probes to the lead wires or cables on either side of the resistor or other device you wish to measure. https://homemakerguide.com/how-to-read-a-multimeter/, Homemakerguide.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Tips to make the perfect hanging basket of flowers. The battery can read more than 12.4 volts, but not enough Cold Cranking Amps (CCA) output to start the engine. If you're testing in a car, don't start the car, and don't try to turn on any fans, lights, or anything else in the vehicle, as you could overload the meter. Using the best multimeter devices to measure resistance is one of the simplest things you can do with this device. For example, if what you are measuring is on a vehicle, the engine’s vehicle should not be running. Ricky Andromeda has been writing since 1999. You can now conduct the test confidently by yourself if you follow the above guide. Many feel that what took hours in the calculation is now quickly turning into minutes! In case you connect the positive cable to the negative probe, the readings will be negative. You can assume the negative sign on the screen or interchange the probes.eval(ez_write_tag([[300,250],'handtoolsforfun_com-large-leaderboard-2','ezslot_9',106,'0','0'])); The other end should be connected to the negative probe. The very top is for resistance, below is DC volts (DCV) and amps (A), and the AC Volts (ACV). But in older multimeters, this is indicated by 4,נ|�C�~� h@���r��C�U!A9aʡ'^{ 59���|�ÿ @�´��#N� As an analogue multimeter does not contain any active electronics, the diode rectifier used to rectify the alternating waveform has a certain turn on voltage and this will affect the low voltage end of some scales. The current will flow from the battery (source) through the multimeter and then to the appliances. Copyright © 2020 Hand Tools for Fun | All Rights Reserved. Even though you may boast of having a couple of high functioning resistors and maybe the best stud finder in your work shed, an analog multimeter can still come in handy. Ohm setting come in just Ω and kΩ, which represents 1,000 ohms, so be careful not to keep under- or overshooting the resistance range. Note that any power that is not now in the circuit should be off to avoid blowing the multimeter. @�� AC, or alternating current, is typically used in items like household appliances and electric motors, while DC, or direct current, is commonly used in battery-powered motors and devices. 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. A multimeter is an essential tool that electricians and First, familiarise yourself with the scales needed to learn how to read a multimeter volts values. Test AC or DC voltage. Its However, the resistance scale here is logarithmic. If I have 20a breakers in my box, can I assume there is 20a at the outlets? x�u�]k�0����e"3�iڂ�:٠�P؅�B���햶����E�v����}r�Y�:��0����= )�����)�PK���>z(|o0_�unl*�!�Mq�HiH�ж�{ﾇi�W@:�KW�B�Z��r�{�B J4%�(,�-e�g�����|oŞ���܁��5�z̹a5'b��fO���u���5v_��O,�|o���xs�W �X!0FDI�_����S��•�w=�V� s�f>�Pw.����@� T EL��E��q�*�4U��/�����|8�+I:ps�gy����B��:3��[c[x�n�J���� ܯ����F3�Oo8���A��3�z J%A��-_(��T���@�����9��g�(E=A�3(��x6@��� JA1�������'J�A9��r�7 2s�������M�lJ�A���'�3 ma�%���;礟�q2@���Ȃ�;��A�3(��y�� ��%(Q�SGD/������:u��oD�AI*(��OD&L��$�y�=�4�H�Q�t�r����s:@�.�,�r���/��]�V� �̂2��h�����|�1��wP�-8c�B��-8CPJ���?�>�������2�� TNP����P!A)9(W. How to Read Amps on a Multimeter. eval(ez_write_tag([[250,250],'handtoolsforfun_com-banner-1','ezslot_13',105,'0','0'])); Do This applies to any circuit breaker. <> Depend Therefore, it is important to check from the instruction manual the maximum amps that the multimeter can handle.eval(ez_write_tag([[468,60],'handtoolsforfun_com-box-4','ezslot_6',104,'0','0'])); The advantage of using a plug-in immobilizer is because it can widen the amps range. makes use of a galvanometer to show the reading of a current, The necessity of connecting the red wire to the positive probe is to get a positive reading on the multimeter. must provide you with a number for you to multiply the reading by. Next, hold the two pins against the resistor’s ‘legs’. This means the highest reading on the scale will be the maximum, as an example reading at a 30 V setting, your maximum reading will be 30 volts. If you’re measuring a circuit without the amp clamp and the reading has a negative sign in front of it, it means you put the leads on backward. similar distance signifies a varying value change depending upon your We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free.

This article was co-authored by Jesse Kuhlman. It’s also important to highlight that overloaded meter will show readings ‘OL’ or ‘1’, but there’s no need to panic, using the selector knob, adjust the mode to 200kΩ or 2MΩ. However, like experts from homemakerguide tell us; having the best tech devices is useless if you can’t use them. There are readings that will be detected on the screen of the multimeter. individuals rely on for checking the resistance (ohms), current (amps), Thank you all! Jesse Kuhlman. @5¨�����i_�O'�֠�2��S�ГiG Last Updated: May 29, 2020 The initial days or weeks of using it could be very challenging, especially when reading it. Can I Test an Electric Fence with a Multimeter? ʇ�r����=�K t%�������2 ���r���� IP: Learn More → A multimeter is an electronic hobbyist's best friend, as it can measure voltage, resistance and current continuity. There are 16 references cited in this article, which can be found at the bottom of the page. The maximum amps may also be called the maximum current. If no number appears or a strange symbol is displayed, you need to readjust your voltage knob to a better range. Some dials range automatically; therefore, you do have to adjust it manually. When you use a clamp, it doesn't become part of the circuit, unlike when you are just using a multimeter. decibel (dB) scale is usually the smallest and lowest on the analog There's no need to unplug the black wire. <>/Pattern<>/Font<>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 720 540] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> When it comes to the analog multimeter, DC voltage is measured with a series resistor connected between the meter movement and the circuit under test. Seems like a pool of closed-end parenthesis within a row. Hence, here, a color code of 10kΩ could read up to 10.5kΩ or as low as 9.5kΩ. 3 0 obj Years of work and experience have shown us that Analog amp meters huge amounts of manual calculation. How can I work out a parallel DC circuit's amperage without using a machine to measure it? Some dials are auto-ranging, which means you do not have to manually adjust a dial. letter “V” you see on your multimeter stands for voltage. Read the result. Learning how to read analog multimeter scale values is a rather quick process. Jesse Kuhlman is a Master Electrician and the Owner of Kuhlman Electrician Services based in Massachusetts. the capacitance settings while the Hz (Hertz) measures the AC circuit’s Read the manual to get the exact answer. Has a symbol of capital V with three hyphens on top of it and one line above that. Current is also called amperage and is measured in amps (A), milliamps (mA) and microamps (μA). We may earn money reviewing products from the affiliate links on this site. If the fuse in your circuit is 12A, for example, and your meter has 2 fused ports for 10A and 300mA, you are out of luck, you might ruin your meter. If you're working on an electrical project, sometimes you may need to check the amperage, or how much electricity is flowing through the circuit. For example, if measuring a 9-volt battery, turn the dial to 10V or higher if necessary. Assuming it's a 220v system/circuit, you'll need #10 (10/2) wire tied to a two pole 30 amp breaker, and hopefully you have two free spaces in the panel for the breaker. R (resistance).

The ticks go 0 to 100% (marked 0 thru 10), so for the 50 uA scale you read the ticks from the 50 scale, and for the 2.5 mA, 25mA and 2.5A you use the 250 scale and mentally place the decimal point where needed. This reading will show you the amperage, or the current, of the circuit you're testing.
