Learning Event 3:
DESCRIBE CONSTRUCTION AND USE OF MULTIMETERS
You know that most ohmmeters that you will use will be part of a multimeter. The LVCT had
more than one meter, but it is not a "multimeter." It measures only DC voltage and amperage and
is therefore called a low voltage circuit tester. The "multimeter" measures AC and DC voltage,
In Figure 25, the first difference you notice between the multimeter and the LVCT is the
multimeter has only one dial. This dial has scales to indicate values for each of the tests the meter

There are several kinds of multimeters, made by different manufacturers. In general, most will
have the same jacks and controls.
