Measuring

You can measure the following parameters:
l D. O. concentration
l Oxygen saturation
l Oxygen partial pressure
The Oxi meter is supplied with the following functions:
l AutoRange (automatic switchover of the measurement range),
l The AutoRead function (drift control) for checking the stability of the
measurement signal. This ensures the reproducibility of the measur-
ing signal. For details of how to switch the AutoRead function on/off,
see page 18.
Perform the following preparatory activities when you want to measure:
1 Connect the D. O. probe to the measuring instrument.
2 Calibrate or check the measuring instrument with the sensor.
How to calibrate is described in section 4.3 from page 19.
3 Immerse the D. O. probe in the test sample.
4 Select the measuring mode with <M>.
Note
Incorrect calibration of D. O. probes will result in incorrect
measured values. Calibrate at regular intervals.
The D. O. probe has an integrated temperature sensor that always
measures the current temperature of the test sample.
