CAUTION
Do not permit the sample line to contact the evaporator plate
inside the refrigerator at any point along its run, or the line will
freeze during operation.
3.2 Connection to a Flow
Meter
If you want to run the sampler in the flow-paced mode (taking
samples after a specific volume of flow has passed, rather than at
timed intervals), you must use a flow meter to pace the sampler.
The flow meter is designed to send signals to the sampler called
flow pulses that indicate a specific volume of flow has passed
through the flow stream. You program the flow meter to send one
flow pulse to the sampler for whatever volume of flow you have
selected. If you do not know how to do this, consult the flow
meter instruction manual for information on programming the
flow meter. When you have programmed the sampler to take a
sample after the desired volume of flow has passed, the sampler
will count the flow pulses from the flow meter and take the
sample when the proper number of pulses has been received. (Of
course, if you want, you can also take a sample after only one
flow pulse.) When the sampler takes a sample, it will send a
signal back to the flow meter, indicating a sample event has
occurred and also the bottle number of the sample.
The flow meter should be any Isco 3000, 4100, or 4200 series flow
meter.
A flow meter-to-sampler cable terminated with two, six-pin
M/S connectors is available from Teledyne Isco for this purpose.
Make sure you have the newer flow meter-to-sampler cable. The
newer cables have the F pins on the two M/S connectors wired
together. Do not use a cable you may have from an earlier application
without first checking for continuity between the F pins.
Connect either end of the cable to the male six-pin M/S connector
on the base of the sampler controller section. This connector has
