Dissolved Oxygen Transmitter
Appendix F. Quick Guide - Oxix Calibration
Valid from firmware version 846003-001, a new calibration menu and method
have been introduced in the Oxix converter.
A factory calibration of both zero point and span has been made at delivery;
these calibrations can be done independently of each other. It is not usually
necessary to calibrate. We recommend checking the zero position every 6 to
12 months.
The calibration is saved in the converter and you will need to conduct a new
calibration if the sensor is moved to another converter.
We recommend conducting a factory reset of the sensor before conducting a
new calibration, since you avoid that any errors in an existing calibration affect
the new calibration.
We have also added a menu with the possibility of adjusting salinity levels in
the measurement.
