CVS4200 / BVS4300 Stationary Samplers
This option is used for discrete sampling
applications, to successively deposit one
sample to each of a programmed number of
containers on any given sample initiation.
The consecutive setting is programmable up
to 99 containers per sample initiation.
Allows the sampler to deposit equal sample
volumes into a predetermined number of
containers per programmed day. Each day
may have any number of samples taken,
dependent on the SAMPLE INITIATION
mode chosen. Deposits are made to as many
as 9 containers per day, to a cumulative total
of 24 containers. Timing is dependent on the
crystal-controlled Real Time Clock in the
controller. The first program day will be the
current day the programming is done.
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 c
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
an
step occurs.
7.6.6.2 PROGRAM TYPE - Composite
The following sequence of entries are made
on the Touchpad to describe how the
Sampler controller is to store the samples it
takes, in the hardware specified in its
configuration. The ACTIVE SETTINGS
are not being altered.
1. Press the SET key.
2. Press the PROGRAM TYPE key.
