How To Read A Digital Multimeter
The scale of resistance has been changed so that each number on the R scale can be read directly. If the conductive path is broken (possibly due to a wire that has come loose in your circuit, or a bad solder connection), the multimeter will not beep. It will happen in a split second and without any real audible or physical indication that something is wrong.
However, if the range is set on 20V and you're measuring an application that puts out more than 20V, the display will read OL, or overload. Plug your probes into the appropriate sockets. Add a comment Add a comment Add Comment 1024 Step 14 Edit Switch on your multimeter, and set the dial to resistance mode. How To Use A Multimeter On A Car DO NOT put a 10A fuse where a 200mA fuse should go.
This multimeter is a combination of auto-ranging and manual ranging. How To Use A Multimeter Pdf To measure current, follow these steps: Plug your red and black probes into the appropriate sockets (also referred to as "ports") on the multimeter.

When multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites.
How To Use A Multimeter Pdf
Different multimeters have different symbols for measuring direct current (and the corresponding voltage), usually "DCA" and "DCV," or "A" and "V" with a straight bar above or next to them. http://www.sciencebuddies.org/science-fair-projects/how-to-use-a-multimeter.shtml The "AC" scale is for reading AC voltage. How To Read A Digital Multimeter In this tutorial we will cover measuring voltage, current, resistance and continuity. How To Use A Multimeter To Test Voltage Flag as...
for this info!!! Most multimeters can measure AC (alternating current) systems, but AC circuits can be dangerous. It doesn't matter which probe goes where; continuity is non-directional. As before, if your circuit is continuous, the screen displays a value of zero (or near zero). If Where voltage is measure by poking at VCC and GND (in parallel), to measure current you have to physically interrupt the flow of current and put the meter in-line. How To Use Analog Multimeter
This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test Bob. Measuring current can be tricky the first couple of times. If you don't know something, ask questions and ask someone more experienced.
A soft knob is usually indicative of a shoddy meter. Multimeter Function You will need to slide the face sideways with a little force to disengage these hooks. Productivity.
Touch two parts of your circuit with the probes.

How is that done? Make: Tools, which uses the same teaching techniques as Make: Electronics to explore and explain the use of workshop tools. Milli-volts are 1/100th of a volt. Find out who represents you in the Nebraska legislature.
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. With a multimeter, you can make sure batteries are actually dead before recycling them by testing their voltage. Manufacturers don’t want a Fair Repair bill. Who has the highest resistance?

Below is an overview of what multimeters are and what they are useful for. It cannot be placed "across" the circuit the way a voltmeter is used (otherwise the meter will probably be damaged).
Current flow is represented by the yellow arrows. How do I do a continuity check? Figure 7. This will allow you to read from 2.00 to 19.99.
Use the continuity check on your multimeter (if it has one) to test which parts of the circuit are directly connected to each other. (Warning: Old circuit boards are constructed with Things You'll Need Multimeter. Using a multimeter to do a continuity test. We've got it.
Since not all multimeters have these features, we will not cover them in this tutorial.
