Input Displays – You can easily identify input displays because
they contain a blinking word or number. The blinking word or
number serves as a prompt for input and is said to be "selected."
When the input displays shown below first appear, the word
"PROGRAM" and the sample volume entry "250" will be
blinking. Italic characters are used to represent blinking words
or numbers in illustrations in this manual.

Display Numbers – Nearly all input displays have a number
assigned to them. The number is used to cross-reference the
input displays with an explanatory listing found in Appendix D.
If you have a question about a given input display, you can easily
locate the description of the display.
To access the display number, press the stop key when viewing
the input display. To see the display number, press the stop key,
read the number from the display, then look up the corre-
sponding number in Appendix D.
Displays With Choices – There are two types of input displays:
displays that prompt you to make a choice (between time-paced
and flow-paced sampling, for example) and displays that prompt
for numeric input (sample volume, for example). In displays that
ask you to make a choice, you must select one of as many as four
alternatives placed in brackets. The display above prompts you
to select the program or configure sequence. The choices,
"PROGRAM" and "CONFIGURE," appear in brackets.

Numeric Input Displays – A numeric input display prompts
you for input by blinking the currently stored number. (In the
display illustrated above, the number "250" will blink to prompt
you to enter a value.) If the blinking number is acceptable, you do
not need to type the number again: pressing the enter/program
key will store the number and advance the program to the next
step. To enter a new number, press the appropriate numeric keys,
then press the
