In the power-on state, the display is continuously updated with each new DC
voltage reading. Along the bottom of the display are a series of annunciators.
These annunciators alert you to a variety of conditions. For example, the
SMPL annunciator flashes whenever the multimeter has completed a
reading. Table 6 describes the meaning of each display annunciator.
