<strong>6700</strong> SAMPLERS<br />
A flow-through chamber (available from YSI), which will allow<br />
aYSIsondetobecontinuouslywettedeveninstorm<br />
applications, will be supported as follows:<br />
One of the I/O lines can be used to control an external<br />
pump. The external pump is used to refresh the liquid in<br />
the flow-through chamber. If selected for this purpose, the<br />
signal on the I/O line will be high when the sampler<br />
requires YSI sonde readings. The signal will become high a<br />
user enterable time before the readings are taken and<br />
remain high until all readings have been taken.<br />
To conserve power, the reading interval will always be the<br />
data storage interval. (The 30 second rate if a YSI reading<br />
is used in an enable condition will be ignored.) Readings<br />
will be taken continuously if the backlight is on.<br />
Additional codes have been added/modified to support the YSI<br />
parameters when using the serial output option. See also Table<br />
