The
amplitude of
the Earth’s
field is
abnormal
Erroneous
scaling factor
If the scaling factor applied to convert volts into field
amplitude is erroneous, the field reading will appear
either systematically high or low depending on the
error on the scaling factor. Please check the conversion
rate used in the acquisition software if applicable.
The noise on
the output
is much
higher than
the specified
noise at low
frequency
Ambient
environment is
noisy
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 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 Mag646 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 Mag646 electronics board, to prevent irreparable
damage.
The Mag646 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 Mag646 to Bartington Instruments for calibration at the recommended intervals.
Refer to the Calibration Certificate for further details.
9. End of Life Disposal
This product (electrical and electronic equipment) should not be placed in municipal waste.
Check local regulations for disposal of electronic products.
