AUTO MODE
When the system is in auto mode, the user will
be alerted by 2 beeps indicating that the filter
should be inverted to achieve the target sam-
ple volume. The system will continue to meter
the water contained in hose and filter housing
even after the nozzle is removed from water.
Thus, the Volume Offset value accounts for
the water in the filter and tubing when target-
ing specific sample volumes.
When the start button is pressed in Auto
Mode a new sample ID and data record will be
generated (equivalent to pressing the Reset
button).
MANUAL MODE
In manual mode the system will not generate a
new data record on Start, and it will not gen-
erate an alarm for Target Volume. This mode
is useful when the user does not know what
the Target Volume should be for a given en-
vironment/filter pore size, or when the pump
is frequently started and stopped for a single
filtration event (e.g., Transect sampling).
