Press ENTER. The display will show the
response “TIMED STEP Total Bottles nn”.
The two digits, nn, will be flashing,
indicating they can be changed by scrolling
with the arrow keys.
Press ENTER. The bottom line of the
display now reads “Step Intvl 00:00”. A
previously set value is displayed. One of the
digits is flashing, prompting for first digit of
a numeric input. The format is HH:MM.
Using the number keys (0-9) enter the time
interval at which the stepper MUST
advance, regardless of SAMPLE
INITIATION settings. The program will
repeat this action at the set interval except
during an ongoing sample cycle, when it will
advance the stepper after the sample cycle is
complete.
Press ENTER. The display now reads
PROGRAM TYPE <ENTERED>.
The controller has now been given a new
value for PROGRAM TYPE. The new
value resides 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 be set to perform as
a Timed Step Sampler in conjunction with
the parameters programmed under the
START DELAY and SAMPLE
INITIATION variables.
