How-To's

The year in which you purchased your analyzer will indicate if you can perform the annual service yourself or if you are required to send in your analyzer for its annual service. Only analyzers purchased after September 6, 2022, can be self-serviced. To perform the annual service yourself, follow the desiccant and oxygen sensor replacement instructions.

Users should use the medium user piece if their ventilation range is between 30-160 L/min. The large user piece is used in most cases by professional high-intensity athletes or users with a ventilation range 40-220 L/min

You should choose whichever gender closely matches your physiology in terms of hormone levels. The only data affected by gender is the “VO2max vs population” and “RMR vs population” percentile bars in the PDF reports. There will be no changes in the data for primary measurements like RMR, VO2max, Training Zones, or VT based on your selected gender.

Troubleshooting

There are 4 reasons why you cannot complete the syringe calibration:

  1. The analyzer has not completed the start-up zero calibration procedure.
  2. The humidity sensor is reading values above 70%. If the oxygen sensor was damaged by water the sensor may read values even higher than ambient humidity, we recommend that the desiccant cartridge be replaced, and the analyzer be placed in a zip lock bag with silica gel packs for 48hrs, please contact support if the issue continues after the 48hr period.
  3. The volume provided to the analyzer is reading more than 15% off the expected value, due to a leak in the syringe hose and the analyzer will reject the breaths it receives.
  4. You may be pumping the syringe too fast, try to follow the audio and visual calibration metronome in the mobile app.

Try replacing the battery with a known fully charged battery. If the issue persists, use our Contact page, and complete the form with ‘Technical Support’ selected under the ‘Type of request’ drop down menu.
