Calibration Of The Oxygen Sensor; Calibration In Air At 100; Calibration With Zero Oxygen Standard - XS OXY Series Manual

The Future Starts Now

3. Calibration of the oxygen sensor

The luminophore of the optical sensor is subject to aging and wear, so you need to calibrate it regularly in
the air.

3.1 Calibration in air at 100%

The ordinary calibration is made at 100% in air.
Turn the instrument on, rinse the probe with distilled water, dry thoroughly the probe with a paper towel
and proceed as follows:
1) Place the probe in the air with the membrane downwards and wait 2 minutes.
2) Press
corner shows "100".
3) When the reading is stable and appears
shows End and the meter enters in measurement mode.
The oximeter is calibrated and ready for use.

3.2 Calibration with zero oxygen standard

Normally it is sufficient to calibrate the instrument in the air at 100% as explained previously. However in
some cases it may also be necessary to calibrate at 0%, for example when:

You change the probe or luminophore with a new one

The probe is not used for long period

The instrument does not calibrate at 100%, in which case calibrate before at 0%

The instrument does not measure correctly
For the calibration at 0% proceed as follows:
Turn the instrument on, rinse the probe with distilled water, dry thoroughly the probe with a paper towel
and proceed as follows:
1) Put the probe in the zero oxygen standard and wait 5 minutes.
2) Go to the parameter P5.1 of setup menu, press the
upper display will flash "CAL" and the lower right corner shows "0", gently shake the probe in the
standard.
to start the calibration process, the upper display will flash "CAL" and the lower right
icon, press button to confirm, the display
key to start the calibration process, the
