You can connect the sampler to an external instrument (Figure
2-11) for a variety of reasons. Typical reasons include:
• Receiving flow pulses from a flow meter device for
variable time or variable volume sample collection.
• Receiving an enable pin signal to enable sampler
operation once site conditions warrant sample collection.
• Sending a three-second event mark at the beginning of
every sample collection event.
• Receiving a linear 4-20 mA analog representation of the
flow rate for variable time or variable volume sample
collection.
• Sending alarm signals when user-specified sampler
events occur.
These types of connections can be categorized as Standard Isco
device connections or other device connections. Each type is
discussed in sections 2.9.1 and 2.9.2, respectively.
This rear-panel connection may also be used for communicating
with a computer for the purpose of collecting reports. Please refer
to section 4.3.2 for more information about this feature.
You can connect the sampler to an Isco 4100 Series flow logger or
a 4200 Series flow meter. With these Isco instruments you can:
• Receive flow pulses for variable time or variable volume
sample collection.
• Receive an enable pin signal to enable sampler
operation once site conditions warrant sample collection.
• Send a three-second event mark at the beginning of
every sample collection event.
• Power the flow measurement device.
