Spin Wheel
The Spin Wheel performs the same editing function as and described in
the previous paragraph. However, as the wheel is spun, it continues to
decrement (ccw) or increment (cw) the digit under the cursor. This continuous
spin-action is useful for making larger changes to field values and to make real-
time changes to the RF Output.
Keypad
The alphanumeric keypad supports direct keypad edit of a numeric field. Alpha
entry is also supported, but only to allow the naming of user Saved Setups.
Alphanumeric Keys
The alphanumeric keys are similar to those found on a calculator. They include
two levels of characters. The default level includes the digits 0 through 9. The
shifted or second level includes the alpha characters A through Z, _ and /. The
decimal point (.) and minus (−) characters work with both levels. Notice that the
alpha characters are grouped so that three or four characters appear on a single
key, much like the telephone keypad. Use the ALPHA key described below to
access the alpha characters. When you enter an alpha character, push the key
containing the desired character. The first character in the alpha grouping
appears in the field. Push the same key again to advance to the next character in
the alpha grouping.
ALPHA Key
controls access to the numeric (default level 1) and alpha (level 2)
characters. The key operates in a toggle mode. When the light is off, the numeric
characters are accessible. Push to illuminate the key to enable access to the
alpha characters.
NEXT CHAR Key
is functional when the light on is illuminated. After an alpha character
key is pushed and the required character is selected, use to advance the
cursor to the next character position. When the field data is complete, push .
BKSP Key (Backspace)
permits editing of characters during a keypad data-entry session. After you
enter the first character in a field, push to delete the last available character
and allows another character to be entered in its place. This backspace action is
available as long as characters are present in the field.
SPACE Key
functions exactly like the space key on a PC keyboard. Push to insert
a space character to separate any combination of alphanumeric characters.
EXP Key (Exponent)
Push to enter numeric data with an exponent. While entering a number,
pushing ends the numeric sequence by inserting a capital letter E to
indicate that the next number is an exponent.
