Installation & Operation
The essential features for operating the PT878 are the screen and
keypad. Although these features are common on portable instruments,
the PT878 design offers special features to simplify and speed the
operation.
The primary function of the screen is to display information in order
for you to accurately and easily take measurements. The PT878
screen consists of seven parts (see Figure 1-5 below).

The top line of the screen is the status bar, which normally displays
the time and date. However, when you press
the Menu Bar replaces the status bar.
The middle of the screen is the work area, which displays the
measured parameters, numeric measurements, and both bar and line
graphs. However, when you enter a selection on the Menu Bar, this
area displays menu prompts instead. Also, a line at the bottom of the
work area also displays error code messages.
