Configuration Of Dissolved Oxygen And Ozone Sensor Heads - Thermo Scientific Scientific AquaSensors DataStick User Manual

When configuration information is changed in a DataStick, the information remains with the DataStick. If a new sensor head
is installed, the configuration will remain as programmed by the user. It will not revert to default values.
Calibration options Dissolved Oxygen and Ozone sensors are:
•
1-point Sample Calibration: Desired reading is entered for one sample to adjust measurement offset.
•
Air Calibration: Measures the oxygen in air, compensated by the configured atmospheric pressure setting.
Calibration options for temperature are:
•
1-point Sample Calibration: Desired reading is entered for one sample to adjust measurement offset.

Configuration of Dissolved Oxygen and Ozone Sensor Heads

The AquaComm™ CONFIGURE functions can be accessed from a pull-down menu that automatically changes based on the sensor
type connected to the DataStick. When a dissolved oxygen sensor is connected, settings for data filters, units of measure, atmospheric
pressure, salinity, and temperature compensation can be viewed or changed.

Select SENSOR FILTER from the Configuration pull-down menu to view or change the sensor filter constant.
The filter setting can be changed by selecting the edit box and typing in the desired constant. To accept the change, click OK.
To abort the change, click CANCEL.
If the sensor filter is set to 5 seconds, it will take 5 seconds to reach 90% of the final value when the reading changes.
Measurements are averaged to reduce periodic variations.
The default filter setting is 1 second and the maximum filter is 100 seconds. Use zero seconds for a completely
unfiltered reading.
