How to Use a Fluke Multimeter

If you have an electrical malfunction on your hands, there is only one way to determine its source with maximum efficiency, and that is to use a multimeter. Multimeters quantum discrete electrical properties, along with current, resistance and both Ac and Dc voltage. These instruments can be used by both pro electricians and the normal public, and if you choose a Fluke multimeter, you can rest assured that you're using the very same tool that the pros rely on. Either you invest in a brand new multimeter or find a discount Fluke multimeter online or at a business transaction electronics retailer, you're going to need to know how to use it effectively - and safely. Here are some hints:
Measuring Voltage: Begin by plugging the probes into the corresponding jacks on the multimeter; keep in mind that black is negative and the red should go only to the volt/ohm/temp jack. If you're measuring Ac voltage, simply turn the dial to the "V" with a wavy line over it; to quantum Dc voltage, turn the dial to the "V" with a solid and a broken line over it. Finally, touch the probes to the outlet or wire you wish to monitor. Measuring Resistance: Start the same way as you would to quantum voltage, but turn the dial to the "Ohm" sign. Then touch the probe tips together and read the resistance of the leads. You should be aware of the fact that the measured value of a resistor can differ from its rated value, normally by 0.1% to 0.2%. Measuring Current: Of the three uses for your Fluke multimeter, measuring current is the one that carries the many possible for danger. Before attempting this measurement, make sure to take all principal protection precautions in order to avoid electrocution or serious damage to the meter. First, never endeavor to make a determination if the open-circuit possible to earth is greater than 1000 volts. All the time check the fuses on your meter before beginning your measurement, and take care to use the allowable terminals, function and range. Finally, never place the probes parallel to any circuit or component. Once these protection measures have been carried out, you're ready to begin! Turn off the power to the circuit and removal high voltage capacitors. Then, insert the black lead into the Com terminal for currents between 6 mA and 400 mA, or insert the red lead into the A terminal for currents above 400 mA.
