YSI 600 Sonde Setup
When you attach a sonde to the sampler, you must configure the
sampler’s hardware setup. The YSI 600 setup and calibration
screens follow the rain gauge setup screens.
You can configure the sampler for any or all of the YSI 600 read-
ings: pH, Dissolved Oxygen, Conductivity, and Temperature. The
conductivity readings represent one of the following:
• Specific Conductance in mS/cm (millisiemens/centimeter)
(Requires a specific conductance temperature coefficient)
• Salinity in parts-per-thousand
• Total Dissolved Solids (T.D.S.) in grams/liter
(Requires a T.D.S. scale factor)
• Conductivity in mS/cm
The YSI 600 setup screens are shown in Figure 42 . Consult the
YSI 600 manual for specific conductance temperature coefficients
and T.D.S. scale factors.
YSI 600 Sonde Communications Test
The “TEST YSI 600 COMMUNICATIONS?” screen appears during
the YSI 600 Hardware Setup if the 6700 has not successfully com-
municated with the Sonde.
If you answer YES, the sampler evaluates the communications link
with the sonde and then sets the YSI 600 data transfer protocol. It
is important that you allow the sampler to complete the test; dam-
age to the YSI 600 Sonde could result if power is interrupted during
the communications test.
YSI 600 Sonde Calibration
The YSI 600 Sonde requires initial and periodic calibration. Table
10 lists the supported calibration methods. Refer to the YSI 600
Sonde Manual for calibration procedures.
Table 10 Supported YSI Calibration Methods
The 6700SR also can support the YSI 6820 and 600XL Sondes
when the program option is enabled. Refer to
Chapter 6 for more
information about the additional YSI sondes, and to Figure 43 for
the menu charts.
