Salinity

Salinity
Salinity is determined by calculations derived from the conductivity and
temperature sensors.
When a conductivity sensor is installed, the instrument will automatically use
the salinity measurement for DO and “As Measured” will be displayed. If no
conductivity sensor is installed (
e.g.
ODO/T cable assembly used), the salinity
value will be user-selectable.
ODO Cap Prompt

ODO Cap Prompt
The handheld can remind users when it is time to replace the ODO Cap based on
a user-defined interval. To set the reminder, select ODO Cap Prompt and
input a
number in months
. YSI recommends enabling this setting to match the warranty
period of the ODO Cap:
•
ProDSS ODO Sensor Cap [SKU: 626890] =
12
months
The handheld will automatically recognize the last time the ODO Sensor Cap
coefficients were updated and alert the user when the Cap is due for replacement.
To disable the prompt, simply enter
0
for the number of months.
GPS (Optional)

GPS
Some handhelds feature a built-in GPS. GPS turns the handheld Global
Positioning System On or Off. The
symbol is shown when a GPS signal is
received.
When enabled, the GPS coordinates will be saved with the Calibration Record and
logged data. Note that the battery will drain more rapidly when GPS is enabled
than when it is not enabled.
NOTE:
GPS data will be most accurate when there is a clear line of sight to
satellites. It may be difficult for the handheld to receive a good GPS signal
when under canopy or indoors.
