automatically. The wiper functions bi-directionally. A selection of “1”
results in three passes of the wiper over the optical face, twice in one
direction and once in the reverse direction. In most applications, a single
cleaning cycle is adequate to keep the optical surface free of bubbles and
fouling. However, in particularly harsh environments additional cleaning
cycles may be needed. This item will only appear if a turbidity,
chlorophyll, or rhodamine WT sensor is enabled in the Sensor menu.
Wipe interval
Default: 1 In applications where the instrument is collecting data in SDI-12
communication mode, the wiper mechanism of the probe should be
activated automatically in a periodic manner to clean the optical surface
for fouling and bubbles. The value entered at this selection is the number
of minutes between each automatic cleaning cycle. Thus, if Wipe Int is
set to “5” and the instrument is in the Run mode, the wiper will activate
every 5 minutes with no manual input. This item will only appear if a
turbidity, chlorophyll, or rhodamine WT sensor is enabled in the Sensors
menu.
The value of Wipe Int is sometimes overridden when the instrument is
set up in the Unattended sampling mode. Under these conditions, the
wiper will be automatically 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
Default: 1 This is the number of wiping cycles when the sonde is in SDI12 mode.
The wiper 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
6026 Default: 0.3
6136 Default: 0.6 This entry sets the coefficient for the temperature compensation of
turbidity readings from the 6026 and 6136 sensors. The default values
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.
