5. Opsætning og første brug
Follow these steps to prepare your analyzer for use:
- Installer batterier:
- Locate the battery compartment cover on the back of the analyzer.
- Use the provided small screwdriver to unscrew the retaining screws and remove the cover.
- Indsæt 3 AAA-batterier, og sørg for korrekt polaritet.
- Sæt dækslet på igen og fastgør det med skruerne.
- Install Oxygen Sensor:
- The oxygen sensor is typically packaged separately to prevent premature exposure to air.
- Unscrew the cap from the sensor port at the bottom of the analyzer.
- Carefully remove the new oxygen sensor from its protective packaging.
- Screw the sensor into the sensor port until it is finger-tight. Do not overtighten.
- Attach T-Piece Adapter:
- The T-piece adapter allows for sampling from various gas sources.
- Firmly push the T-piece adapter onto the top port of the analyzer.
- If using tubing for inline sampling, connect one end of the tubing to one side of the T-piece.

6. Betjeningsvejledning
To ensure accurate readings, proper operation and calibration are crucial.
- Tænd: Press the power button (usually marked with an 'I' or power symbol) to turn on the analyzer. The display will illuminate and show the current oxygen concentration.
- Calibration (Fresh Air):
- Before each use, or if the device has been stored for a long time, calibrate the analyzer in fresh air (20.9% oxygen).
- Ensure the T-piece is open to ambient air, or no gas source is connected.
- Press and hold the calibration button (often marked with a 'CAL' or similar symbol) until the display shows "20.9%" or indicates successful calibration. Some models may have a one-button calibration feature.
- Lad aflæsningen stabilisere sig.
- Foretag en måling:
- Connect the T-piece adapter to your oxygen source (e.g., scuba tank valve, oxygen concentrator outlet). For scuba tanks, ensure a snug fit with the rubberized dome.
- Slowly open the valve of the oxygen source to allow gas to flow through the T-piece and over the sensor.
- Observe the digital display for the oxygen concentration reading. Allow a few seconds for the reading to stabilize.
- Once the reading is stable, note the measurement.
- Close the oxygen source valve and disconnect the analyzer.
- Sluk: Tryk på tænd/sluk-knappen, og hold den nede, indtil skærmen slukker.
7. Vedligeholdelse
Regular maintenance ensures the longevity and accuracy of your MAXO2+ Oxygen Analyzer.
- Rensning: Tør analysatorens yderside af med en blød kludamp klæde. Brug ikke slibende rengøringsmidler eller nedsænk enheden i vand.
- Udskiftning af sensor: Oxygen sensors have a limited lifespan (typically 1-2 years, depending on usage and exposure). Replace the sensor when readings become erratic, calibration fails, or the "low sensor" indicator appears. Follow the sensor installation steps in Section 5.
- Udskiftning af batteri: Replace batteries when the low battery indicator appears on the display or the device fails to power on. Follow the battery installation steps in Section 5.
- Opbevaring: Store the analyzer in its waterproof case in a cool, dry place when not in use. Ensure the sensor port is capped or the T-piece is attached to minimize sensor exposure to ambient air, prolonging its life.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | Døde eller forkert installerede batterier. | Udskift batterierne, og sørg for korrekt polaritet. |
| Unøjagtige eller uregelmæssige aflæsninger. | Sensor needs calibration, old sensor, or sensor not properly installed. | Perform fresh air calibration. If problem persists, replace the sensor. Ensure sensor is tightly screwed in. |
| Calibration fails. | Sensor is at the end of its life, or calibration environment is not fresh air. | Replace the oxygen sensor. Ensure calibration is performed in an area with known 20.9% oxygen. |
| No gas flow through T-piece. | Obstruction in tubing or T-piece, or gas source not properly connected/opened. | Check tubing for kinks. Ensure T-piece is clear. Verify gas source connection and valve. |
