Calibration point Zero
•
Access this setup menu to start the calibration with Standard Zero Oxygen of the polarographic sensor
(see paragraph "Zero Oxygen Calibration").
•
Once the operation is completed, the device returns automatically to measure mode; the beaker
0.0
indicates the point % 0
performed.
Last calibration data
Access this menu to view the report on the last calibration performed. The
information provided on the last calibration are: Date and time /
Temperature / Barometric pressure / Salinity / Offset / Efficiency.
Due calibration
Access this menu to set a calibration deadline; this option is very important in GLP protocols.
•
By default, no calibration deadline is set; use the directional keys
hours that must elapse between two calibrations and confirm by pressing the button
•
If a calibration deadline is set, it is displayed in measure mode by icon
•
When the calibration deadline is activated, the instrument prevents further measurements for that
parameter, until the calibration is renewed, or the deadline deactivated.
•
The error icon
sensor again and perform new measurements.
Salinity Compensation
The salinity of the sample to be measured influences the partial pressure of the dissolved oxygen.
For a correct measurement, it is necessary to set the salinity value of the sample. If oxygen
measurements are carried out on salt or sea water samples, it is important to modify the measurement by
setting the indicative salinity value of the sample. The average salinity of the sea water is 35ppt.
Auto: The salinity measurement is acquired automatically through the conductivity cell.
•
Important: Make sure you have connected the conductivity cell correctly and that the measuring chain is
properly calibrated.
Manual 0.0 ... 50.0 ppt: Using the directional keys, insert the value of salinity.
•
Temperature calibration
All the instruments of this series are pre-calibrated for a correct temperature reading. However, if there is a
difference between the measured and the real temperature (usually due to a probe malfunction), it is
possible to perform an offset adjustment of + 5°C.
After the connection of the temperature probe in the right measuring channel, use the directional keys
and
to correct the temperature offset value and confirm with
