Step 4. When the divider is connected to a voltage supply, a reduced voltage is available at the junction between the resistors an example is the volume control on a radio.
Thanks Michael for the feedback! Plug the black ground probe lead into the COM socket on the meter see photo below. Depending on which text editor you're pasting into, you might have to add the italics to the site name.
One comment. In this way if the multimeter is used to again for another type of reading then no damage will be caused if it is inadvertently used without selecting the correct range and function. If you estimate the current being measured will be higher than the value indicated on the lower current socket, connect the probe to the higher current socket, otherwise you'll nd up blowing a fuse. Past 24 Hours: The advantage of this is that a circuit doesn't have to broken to insert a meter in series, and power needn't be turned off as is the case when measuring current on a standard DMM.
Jeff Suovanen and 3 other contributors. The croc clip can be connected to ground in the circuit, freeing up one of your hands. Autoranging Meters Autoranging meters detect the voltage and select the range automatically to give the most amount of significant digits on the display.
This should be about 0. A potential divider Google it for more details consists of a number of resistors connected in series.
When the black probe is in contact with the cathode of the diode usually indicated by a bar marked on the component and the red probe makes contact with the anode, the diode conducts, and the meter indicates the voltage. Another way is to cut the neutral core, add 4mm banana plugs to each of the cut ends and plug these into the meter. Turn on the power. Select the item to be measured: The screen displays a value of zero or near zero , and the multimeter beeps. Learning Center About Us.
How to Check Diodes A multimeter can be used to check whether a diode is short circuited or open circuited.
