2.3 Using the Alphanumeric Keypad
This screen is used to enter letters, numbers, and symbols as needed when
programming the instrument. Unavailable options are grayed out.
2.3.1 Setting the Operator ID
Use this option to enter up to 10 sets of operator initials (up to three characters
each) into the instrument. This feature helps record which operator measured
each sample. (See
Section 2.3 Using the Alphanumeric Keypad for more
information.)
The icons to the left of the screen allow a choice of entry modes:
•
Alphabetic—When entering alphabetic characters (ex.
user-entered units), this key allows toggling between upper
and lower case letters. It is inactive on some screens.
•
Symbols—Punctuation, symbols, and numerical sub- and
superscripts may be entered after touching this key.
•
Numeric—For entering regular numbers.
The central keypad changes to reflect the chosen entry mode.
Repeatedly touch a key until the desired character appears on the
screen. A space can be entered by using the underscore on the
YZ_
key.
The icons to the right side of the screen are:
•
Clear Entry
•
Backspace
•
Advance—This key can be used to advance to the next space
in an entry when two adjacent characters occur on the
same key.

Note: Spaces are not available in this function. Use underscore symbols instead.
Alternatively, if an operator ID has been entered and Operator ID is
