You'll find a list of diagnostic and analysis tools:
- Depth Gauge: A depth gauge indicating depth and absolute pressure
- Test Mode: A mode to test the reading of all sensors — pressure, magnetometer, inclinometer, etc.
- ONE-GO(OFF): NOT DOCUMENTED, leave on OFF
- MAGNETO: Magnetic analysis tool

Magneto
You can use the Magneto feature to analyse how strongly your dive equipment affects magnetic readings.
The earth magnetic field ranges from 25 µT to 65 µT depending on your location.
By moving the Mnemo closer to or further from your equipment you'll get a reading of the strength of the magnetic field created by that equipment.
- Here you can see that the magnetic field is between 32.92 and 33.44 when the device is left without any outside disturbance

- When we move a dive light around the Mnemo the magnetic field is this time fluctuating between 30.55 and 37.49 — a huge difference!
