6. Operating Instructions
Switch on the power supply to the Mag900 & Mag901.
Allow the system to warm up after switching on. Refer to datasheet DS4550 for magnetic settling
times.
The Mag900 & Mag901 is designed to have an extremely low magnetic hysteresis.
However, your sensor should not be subjected to magnetic fields greater than their stated
measuring range for extended periods as this could alter the DC offset and other performance
specifications. If this occurs, the offset will exhibit drift as it returns to its original offset
specification.
Caution:
Subjecting the Mag900 & Mag901 to fields in excess of 2 x the nominal range may
cause inaccuracy in future measurements. Degaussing the sensor can reverse such an
effect.
7. Troubleshooting
Your sensor is unlikely to suffer any defects in normal use: no internal components are
serviceable. The most likely causes of failure, and their solutions, are detailed in the following
table.
In the event of any apparent malfunction beyond those described in the table below, please email
, or telephone the Bartington Instruments service team on +44 (0)1993
706565.
Cause
Solution
No operation
Check the power supply. If this is operating
correctly then contact Bartington
Instruments.
Damaged sensor
If any physical damage is apparent to the
sensor then it may need to be replaced. For
information about disposal of a damaged
unit, refer to
High stability circuitry ensures that no interim calibration should be required.
