After configuring your display with the desired parameters, press
Esc or 0
to return to the Main menu.
Even if all of the sensors are enabled, the measurements for those sensors will not appear on your display
unless the parameter is selected in Report setup. In order for a specific parameter to show up on a report:
1.
The sensor must first be enabled (turned on).
2.
That parameter must be activated in the Report setup.
In the above example, if the appropriate sensors have been activated in the Sensor setup section, the
following parameters will be displayed to the computer screen or captured to a computer or data collection
platform when the sonde is sampling: Temperature in C, Specific Conductance in uS/cm, Free chlorine in
mg/L, pH, ORP in millivolts, Turbidity in NTUs and Chlorophyll in ug/L. Date and time will also be
displayed.
NOTE
: Do not attempt to memorize or associate a number or letter with a particular parameter. The
numbering scheme is dynamic and changes depending on the sensors which have been enabled.
The following list is a complete listing of the abbreviations utilized for the various parameters and units
available in the Report setup menu.
