A noisy environment will be picked up by the sensor.
Noise tests should be carried out in a shielded
environment.
Sensor
breakthrough
not filtered
properly
The sensor has a high frequency noise component
referred to as breakthrough in the datasheet. This
signal at the excitation frequency of the sensor, if
unfiltered can be aliased creating an apparent low
frequency noise. Check that a suitable low pass filter
is used or that the signal is sampled at a suitable
frequency (at least twice the breakthrough frequency).
8. Care and Maintenance
Surface dirt contamination on the Mag648 and Mag649™ probe should be removed using
a mild detergent solution only. Electronics should be cleaned with an antistatic cloth only.
ESD protection should be used when handling the electronics board, to prevent irreparable
damage.
The Mag648 and Mag649™ electronics board should be treated subject to ESD precautions.
Note:
Store only within the temperature range specified in the product brochure.
Note: Do not expose to strong magnetic fields while being stored as this can magnetise
the sensor and affect its offset performance.
8.1. Calibration
Return the Mag648 or Mag649™ to Bartington Instruments for calibration at the recommended
intervals. Refer to the Calibration Certificate for further details.
9. End of Life Disposal
This product should not be disposed of in domestic or municipal waste. For information
about disposing of your sensor safely, check local regulations for disposal of electrical /
electronic products.
