Digital Multimeters
Figure P-1
Multimeters are very useful test instruments. By operating a multi-position switch on the meter they can
be quickly and easily set to be used as a voltmeter, an ammeter or an ohmmeter. Some meters have
additional features used to measure capacitance and frequency as well. They have several settings
called “ranges” for each type of meter and the choice of either alternating or direct current
measurements.
Voltmeter
To test for voltage, first determine whether the application you're testing uses AC or DC voltage. Then
set the dial to the appropriate function and plug the red test lead into the correct jack used to measure
voltage.
Like all test procedures, when testing voltage, set the meter to the range just higher than the expected
voltage and decrement it down as needed to increase the accuracy of the reading. If you don't know
the expected range, set the range to the highest one available. Take the black test lead and place it on
the negative polarity point of the circuit you want to measure. The red test lead will go on the more
positive polarity point. When measuring voltage, the test leads of the meter must always be connected
in parallel or “across” the component or circuit to be measured as in Figure P-2 on the next page.
