Probe Menu
Use the Probe (
) key to access the sensor setup menu, set display parameters and unit preferences, set Auto Stable parameters,
change the sensor averaging mode, turn on/off GPS (if available), and manage deployment settings.
Operation
Push the
key to access the sensor menu. Highlight a sub-menu then push the
ENTER
key to view sub-menu options.
Pre-defined or user-selected sensor settings are noted within brackets ([]).

Setup
The Sensor Setup menu will show all sensors connected to the instrument. If
a sensor is connected but is not listed on the Sensor Setup menu (<None>
displayed), check the sensor and cable connections.

Depth
Probes with a depth sensor in the bulkhead can measure virtual vented depth.
The virtual vented depth measurement allows for real time compensation for
atmospheric pressure using the handheld's barometer.
Depth offset: Depth offset can be used if referencing water elevation against a
known value. If a depth offset is entered (in meters), the output value will shift by
the value of the offset.
A common offset entered by the user is the depth sensor location relative to the
rest of the WQ sensors. This value is 18.6 cm on the 1-port cable.
Altitude/Latitude: To compensate for atmospheric pressure based on elevation
and gravitational pull, enter the local altitude in meters relative to sea level and
latitude in degrees where the instrument is sampling.
Latitude effect: Varying latitudes can cause up to a 200 mm change in depth from
equator to pole.
Altitude effect: A 100 m change in altitude causes a 1.08 mm of change to the
depth readings.
