EXIT PROGRAM - Pressing the EXIT PROGRAM key while
in the program sequence will return the sampler to
standby. If you press the
EXIT PROGRAM key while in the
run state, it will halt the program; the message
“PROGRAM HALTED” will be displayed.
•
CLEAR ENTRY - When entering a number, use the
CLEAR ENTRY key to return to the original entry.
•
ENTER/PROGRAM - Press the ENTER/PROGRAM key
while in the standby state to cause the sampler to enter
the interactive state. While at an input display, press
the
ENTER/PROGRAM key to accept an entered value or a
blinking option and direct the sampler to proceed to the
next step.
Numeric Keys – The numeric keys consist of 10 digit keys, a
key, and a key. You use the digit keys to enter quantities and the
arrow keys to move through the configure option list or program
options.
• Left Arrow - Press the left arrow key to select one of
two or more program options displayed when the
sampler is in the interactive state. When more than one
numeric entry is displayed – for example, the hours and
minutes of a time setting – you can use the left arrow
key to step back to a previously entered value. When
entering a number, use the left arrow key to erase the
most recently entered digit. It is also used to step
through display status information and configure option
list.
• Right Arrow - Use the right arrow key to select 1 of 2
or more program options in an input display. You can
also press it to step through display status information
and configure option list.
3.6.3 Displays There are two types of displays: displays that communicate infor-
mation about the sampler’s status and displays that request
input. In many cases, you must respond to a display with the
keypad.
Informational Displays – Informational displays communicate
information about the sampler’s status. For example, when the
sampler completes a sampling program, a display similar to the
illustration below appears. It communicates the sampler’s status
(“DONE”), the number of samples taken (which will vary
according to the program), and the current time and date.
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.”
