Digital
Digital meters display measured values on an LCD (liquid-crystal display) similar to a calculator
(see Figure 4-2). No guessing or interpretation is needed. Analog meters have a needle that swings back
and forth, with line markings underneath (see Figure 4-3). Because digital meters are so easy to read and so
inexpensive, don’t use analog.
