3. Press an ARROW key. Continue until
Interval Time is shown on the display.
4. Press the ENTER key.
When setting the time, a flashing digit
prompts for input from a numeric key. To
set the time, press a numeric key to enter a
value and advance to each digit in
succession. The format is HHH:MM. The
minimum time can be set to 1 minute,
however, practical considerations, such as
equipment duty cycle, maintenance and
service life suggest times of 3 minutes or
longer.
When the five digits are entered, press
ENTER. Any wrong entries will require
re-entry. There are two methods of
correcting a mistake. The digit flashing
“wraps around” and begins again, at which
time the correct entry may be pressed.
Alternately, the arrow keys can be used to
reposition the flashing prompt over the error,
which can then be replaced with the correct
value.
The display will echo the last entry with
<ENTERED>.
The controller has now been given a new
value for SAMPLE INITIATION. The new
values reside in the NEW ENTRIES area of
the controller memory. To make these
changes active, press the RESTART key,
then again press it to confirm your choice.
The controller will then wait the designated
time before taking a sample.
