Periodic maintenance
Cleaning the sensors
There is only minimal periodic maintenance required: the cleaning of the sensors.
Due to their proximity to the sensor coils, magnetic dust particles on the sensor hous-
ing may upset the magnetic field. This would result in erroneous absolute values.
Therefore, it is good practice to wash the sensor(s) periodically with soap and water.
Desiccant exchange
Small amounts of moisture may possibly enter the ENVI-MAG console, even
though it is fully sealed. A cartridge filled with a drying agent (desiccant) is
located under the battery cover, refer to Figure A - 44 on page A7-3 for the exact
location. The desiccant should be dried out periodically as required. A spare
cartridge is supplied as part of the Minor Spare Parts Kit.
To dry out the cartridge:
1. Place the console, face down, onto a flat smooth surface.
2. Unscrew the screws at both sides of the battery cover.
3. Lift off the cover.
4. Pull out the cylindrical plug while gently turning.
5. Place the cartridge in front of a heat source for about one hour. A hair drier
is a good source of dry heat.
6. Clean the connecting surfaces on the cartridge and the access hole.
7. Replace the cartridge.
8. Replace the battery cover.
