6700SR Refrigerated Sampler

Adjust Pacing
This option is available when the running program is paced by Uni-
form Time, Flow Pulses, or Flow Volume. If you select this option,
you are asked to enter a new pacing interval. The sampler logs an
INTERVAL CHANGED event. If the sampler is running a two-part
program and both parts are paced by the pacing listed above, you
will be asked to modify both intervals.
The original pacing interval continues to count down until you re-
turn the sampler to the running program (select RESUME PRO-
GRAM). If the new pacing interval is less than the original count
remaining, the new interval is used.
If the original count remaining is less than the new pacing interval,
the original count will continue to count down to the next sample
event. Subsequent samples are then paced by the new interval.
Adjust Volume
Select this option to change the sample volume within the limits of
the currently programmed sample distribution. For two-part pro-
grams, the sampler displays a screen for changing Part A’s volume
and then a screen for Part B. If you change a sample volume, a
VOLUME CHANGED event is logged.
Adjust Enable
This option is available for extended sampling programs that have
programmed enable conditions. Selecting this option allows you to
change the set-points or ranges for the enable conditions. The sam-
pler displays all of the programming screens that define the thresh-
olds of the programmed enables. You cannot change the type of
enables used or the way they are combined.
If rain is an enabling condition, you also have the option of reset-
ting the rain history.
Power Used
The 6700SR has a “fuel gauge” that gives an indication of power us-
age. The controller keeps track of how much power has been con-
sumed since the last time it lost power. If the controller is powered
by an external battery, this fuel gauge can help you estimate the
condition of the battery.
Keep in mind that the sampler has no idea as to how much charge
was originally stored in the battery (or even if a battery is being
used), and therefore has no idea as to the remaining capacity of its
power source.
Adjust Suction Head
This option is available when you have chosen to enter the suction
head. (The sampler is not calculating the suction head automatical-
ly.) Select this option to enter a new suction head value. If changes
are made, the sampler logs a CHANGED SUCTION HEAD event.
