Operation
Sensor Display
→ Display (Figure 30)
The Sensor Display menu determines the parameters and units that
are shown on the Run screen (Figure 9). The Run screen will only show
measurements for sensors that are attached to the cable bulkhead.
If more measurements are selected than can be displayed on one screen,
a scroll bar will be shown. Use the and keys to scroll through the
measurements.
NOTE: For depth profiling, enable Vertical Position under Depth
Display to view the real-time position of the depth sensor
in the water column. This is helpful in profiling applications
to ensure the depth sensor is lowered to the desired depth
without waiting for the depth data to stabilize.

Auto Stable
→ Auto Stable
Auto Stable indicates when a measurement is stable. Sensors with Auto
Stable enabled will have
flash beside the measurement on the Run
screen.
will flash green when the measurement is stable.
Select a sensor to enable or disable Auto Stable (Figure 31). Then set the
stability threshold parameters.
The Auto Stable stability threshold can be set by percent of measurement
or in the units of measurement selected in the Sensor Display menu.
Enter the stability value, then select Use Percent or Use Meas. Units
(Figure 32).
This threshold is used to compare the last reading with the previous. The
smaller the number entered in % or units, the longer it will take for the
instrument to reach the auto stable criteria.
Example: For temperature in °C, if Measurement Units threshold is set
to 0.2 and the temperature reading changes by more than 0.2
degrees,
will continue to be red until the reading does not
change by more than 0.2°C over the defined sample period
and sample count.
Hold All Readings: After all sensors have reached their stability criteria,
the measurements will be held or ‘locked’ on the display. If disabled, the
sensor measurements will continue to change in real time.
Audio Enabled: An audio alert will sound when stability is reached.
