activated at the interval assigned in the Unattended setup rather than that assigned in
Wipe Int. Thus, in an Unattended study setup at a 15 minute sampling interval, the wiper
will be activated only once every 15 minutes rather than at the indicated Wipe Int of 1
minute.
CAUTION
: If Wipe Int is set to zero, then no wiping will occur either in Discrete or
Unattended Sampling. Make certain that Wipe Int is set to some finite value prior to
setting up an Unattended study or no automatic cleaning will occur.
SDI12-M/Wipe=1
This is the number of wiping cycles when the sonde is in SDI12 mode. The wiper for
the 6026 and 6136 turbidity, 6025 chlorophyll, and 6130 rhodamine WT sensors will
automatically wipe each time this many SDI12 “M” commands have been issued. If this
value is set to zero, then no automatic wiping will occur.
This item will only appear if a
turbidity, chlorophyll, or rhodamine WT sensor is enabled in the Sensors menu.
Turb temp co %/C=0.3 This entry sets the coefficient for the temperature compensation of turbidity
readings from the 6026 and 6136 sensors. The default values of 0.3 (6026) and 0.6
(6136) should not be changed by the user without consulting YSI Technical Support.
This
item will only appear if a turbidity sensor is enabled in the Sensor menu.

When this item is activated, the output of the turbidity sensor is mathematically
processed to minimize the effect of unusual (or “bad”) readings on the overall data
presentation. In most cases, these “spike” events are the result of the chance passage of
large suspended particles across the probe optics just at the time a reading is taken.
Activation of this option generally results in a better display of the “average” turbidity of
the water under examination and its use is recommended for most sampling and
unattended applications.
This item will only appear if a turbidity sensor is enabled in the
Sensors menu.
Chl temp co %/C=0.0
This entry sets the coefficient for the temperature compensation of chlorophyll
readings from the 6025 sensor. The default value of zero should only be changed by the
user after establishing the temperature compensation factor for the phytoplankton sample
in question. See Section 5.12, Chlorophyll and Appendix I, Chlorophyll
Measurements
of this manual for more information.
This item will only appear if a
chlorophyll sensor is enabled in the Sensors menu.
BGA-PC temp co %/C=0.0
This entry sets the coefficient for the temperature compensation of BGA-PC
readings from the 6131 sensor. The default value of zero should only be changed by the
user after establishing the temperature compensation factor for the phytoplankton sample
in question. See Section 5.16, Principles of Operation of this manual for more
information.
This item will only appear if a BGA-PC sensor is enabled in the Sensors
menu.
BGA-PE temp co %/C=0.0 This entry sets the coefficient for the temperature compensation of BGA-PE
readings from the 6132 sensor. The default value of zero should only be changed by the
user after establishing the temperature compensation factor for the phytoplankton sample
in question. See Section 5.17, Principles of Operation of this manual for more
information.
This item will only appear if a BGA-PE sensor is enabled in the Sensors
menu.
From the Advanced menu, select 4-Data filter to display data smoothing options. Type the appropriate
number to activate/deactivate any of the displayed features.
