This option will cause the sampler to step to
a new container regardless of the status of
the SAMPLE INITIATION setting. For
example, the actual sampling may be under
the control of a flowmeter and taking
samples based on the flow rate as
determined by pulses or 4-20mA input to the
controller. When the user-programmed
timed interval has elapsed, the controller
will step to a new container. The Timed
Step can be set for any interval up to 99
hours 59 minutes. Progress of the step timer
can be viewed by selecting View, Program
Type and pressing ENTER twice. Thus you
may view the step timing and the amount of
time until the next step occurs.
