6700SR Refrigerated Sampler
105
YSI 6820 and YSI 600XL Support
This software option will allow the 6700 sampler to be interfaced to
a YSI 6820 sonde or a YSI 600XL sonde.
Table 13 lists the support-
ed parameters (if available on the sonde).
If the YSI sonde is connected and communications are successfully
established, the selections will include only those that the sonde is
configured for. You must configure and calibrate your sonde external
to the 6700 using PC software provided by YSI. Serial communica-
tions must be set to 2400 baud, 8 data bits, 1 stop bit, and no parity.
If the sonde is equipped with the 6026 turbidity sensor, the 6700
will activate the wiper each time the sonde is powered up. In the
case of continuous readings, the wiper is activated after 60 seconds
has elapsed from the time the last wipe was completed.
When using the proper sensor combination, the level readings from
the YSI will be compensated for dissolved solids. This will be espe-
cially helpful in coastal applications where the measurements are
taken in sea water.
You will be able to select up to eight parameters. If level is one of
the measured parameters and no flow module is connected, the YSI
level readings will be used to calculate flow. The Y-FLOW values
can then be used to pace the sampler or as part of an enable condi-
tion. When generating a YSI combined report, if Y-FLOW is calcu-
lated, it will show up on the chart along with the total volume since
the start of the program,
if there is room on an 80 column chart.
Flow rate takes seven columns and is put on after the selected YSI
parameters. Flow volume takes 15 columns and will be the last en-
try in the chart.

You need to configure your
sonde using PC software provid-
ed by YSI. Only parameters out-
put in the units shown in Table
13 will be “seen” by the 6700.
