Final Purge Time: Specifies the amount of time the sampler hose is
evacuated after a sample is collected. The minimum value is 0 s. The
maximum value for SDI-12 control is 280 s. The maximum value for
PakBus®, Pulse, Modbus®, and Time control types is 800 s. The
setting is only active if the Set Final Purge Time is toggled to set .
•
Sample Volume Level Set Time: The amount of time the sample is
evacuated out of the metering chamber back into the intake hose to
reach the desired volume. The sample volume is determined by the
level of the volume set rod. The minimum time is 3 s. The maximum
time for the SDI-12 control type is 30 s. The maximum time is 800 s
for PakBus®, Pulse, Modbus®, and Time control types. The Auto

sample volume to drain into the sample bottle. Minimum time is 5 s.
The maximum time for SDI-12 is 20 s. The maximum time for
PakBus®, Pulse, Modbus®, and Time control types is 800 s. If the
sample volume is greater than 420 mL, the deposit time must be 18 to
20 s. The Auto Deploy routine sets this to 8 s.
• Set Vacuum Time Out: Allows the user to choose the default (two
times the Purge Time) or to independently set the time out. If the
default is chosen and the Purge Time is 0 s, the time out value is 10 s.
This is not set during Auto Deploy.
