Therefore, it is also … 29. Multimeter is CATII 500V and UL listed. For easier, hands-free viewing, choose a multimeter with a stand that will prop it up or hang it on a wall. We use cookies to make wikiHow great. Next, select the range you’ll be testing. Resistance (measured in ohms): The lower the reading, the easier electrical current (measured in amps) flows through circuit material. Generally, the red probe plugs into the “+” meter jack and the black probe plugs into the “-” jack. If it doesn't, then the fuse is blown. Function setting: Ohms (continuity). wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. This is needed to calibrate out any variations in the battery voltage. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Nowadays, most Digital Multimeters have sockets provided to test them, but what will you do if you have those old Analog… Bad reading: An “infinity” reading or one exceeding 120 ohms. Good reading: A “0.00” reading would indicate “zero”—a closed circuit. UNPLUG the blender, set up the VOM and probes, and push each of the blender’s speed switches. When testing DC voltage or amps, match the polarity of the probes to the “+” and “-” terminals of the DC source being measured. You can also buy bulk packs of fuses online. Je nach benötigtem Messbereich kommen dabei Spannungsteiler zum Einsatz. Every dollar contributed enables us to keep providing high-quality how-to help to people like you. Only 4 left in stock. I was more studious and careful with the next multimeter. Auto-ranging gives you the safest testing capacity each time you change back and forth from, say, measuring resistance to voltage readings. One of the easiest measurements you can perform using a Multimeter is that of a resistance. UNPLUG the appliance, remove the front panel and disconnect the mounting bracket that holds the switch. Good reading: 6 volts (this battery’s original rating) Bad reading: Batteries with voltage readings 20 percent below their original rating should be replaced. A multimeter is a black box of electronic circuitry that allows you to troubleshoot just about any type of electrical wiring or device. AA, AAA, C, and D batteries all have 1.5 volts and a 9V has 9 volts. By signing up you are agreeing to receive emails according to our privacy policy. Hold that big picture in your mind, then add these key concepts about both electricity and VOMs: VOMs are tools that an impulsive and foolish person should avoid. The Ohmmeter section of the Multimeter is represented by Ω symbol. 500 AC/DC Volts; CATII 500V; 5 Functions; 16 Measuring Ranges; Tests 1.5V & 9V batteries; UL Listed; Categories: Meters, Multimeters. One way to test if a multimeter is capable of measuring resistance is as follows: First, you will need to purchase a resistor of a known value. If there are slight changes in readings, the needle of an analog multimeter will attempt to track it, as opposed to the digital meter having to wait until the next sample, giving delays between each discontinuous reading (plus the digital meter may additionally require settling time to converge on the value). Unter den Multimetern können die nach einem analogen Messprinzip mit Skalenanzeige arbeitenden Geräte häufig passiv messen, während Digitalmultimeter mit Ziffernanzeige immer eine Energieversorgung (z. Analog multimeters continuously read the test value. Many multimeters color-code their input jacks, so the voltage-ohm input will be red on a model like this. A test for voltage and amps uses the electricity present in a live circuit to power the meter. Homeowners can use this tool to test batteries, check extension cords, and determine why a certain light switch isn’t working. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
