How to read a voltage meter

If there is still no reading , try the following in order: Make sure the test probes are both connected to the circuit. Set the multimeter to “2V” in the DC (direct current) range. Almost all portable electronics use direct current), not alternating current.

If voltage in the circuit is unknown, set the range to the highest voltage setting and set the dial on ṽ. Note: Most multimeters power up in Autorange mode.

You can also use it for checking continuity of wires and fuses.

If you like to DIY, do car maintenance or troubleshoot electronic or electrical equipment, .

If your multimeter is not auto-ranging, knowing which scale to pick can be tricky, especially if you are not very familiar with metric prefixes. Here are two rules of thumb you can follow for measuring voltage, current, and resistance: Voltage: . Subscribe and check out our weekly podcast onor Stitcher. Search for Fix It Home Improvement. It will also explain the basics of electricity and address . This video show you how to read to the correct decimal point. Click the link below for the lowest prices on.

A multimeter is an electronics testing device that, um, tests multiple things, including resistance, voltage, and current. Using certain multimeter models, you can test to be sure that components — such as diodes, capacitors, and transistors — function properly. Some digital multimeters (DMMs) also include mV. First insert the black probe into the COM jack. Before using the ohms settings you need to calibrate the meter.

With the multimeter set to the highest ohms setting and both of the leads touching the meter should read 0. There is always an adjustment . No matter what you call it, they all do the same thing. A decent-quality voltmeter can tell the condition of your . What are Volts, Amps, Watts, and Ohms presented by Katie Nyberg for Galco TV. He demonstrates how to get the Analog Meter started for accuracy in reading. Normal resistors have color codes on them. Robinson also explains how to re.

However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance. Steps for measuring continuity. The beep, an audible indicator, permits technicians to focus on testing procedures without looking at the multimeter display.

Never use the meter if the meter or the test leads look damaged.
