Fig. 13-3 The Alphanumeric Keys

Alpha Entry Mode

Most numeric keys have alphabetic characters printed on them. These

characters can be accessed when the alpha entry indicator appears in the

title bar. In the alpha entry mode, a cursor appears below the active position.

Repeated pressing of an alphanumeric key sequences through the values

printed on the key. After the desired character is selected, the cursor is

moved to the next position using the left or right diamond keys. Special

characters are available using the up and down diamond keys.

Numeric Entry Mode

In the numeric entry mode, only the numerals 0 through 9 and the decimal

point can be entered. When negative values are allowed, pressing the FCN

and +/- keys toggles between positive and negative values. The numeric

value may also be increment and decremented using the up and down

diamond keys.

Always finish numeric entries by pressing the Enter key.

Multiple Choice Mode

This mode allows you to use the diamond keys to sequence through a series

of choices that appear in the Edit Box.

Printing

Any measurement mode screen can be printed directly. When you press the

Print key, the current measurement screen is printed. To print a

measurement file, simply view the file and print it as you would a current

measurement screen.
