Note:
The length of the cable is limited by the voltage drop in the power supply lines
and the capacitance between the cores. For this reason the cable should be limited to a
maximum length of 600 metres.
Bartington Instruments can supply cables for connection of the sensor to the PSU1, Magmeter,
SCU1 and Spectramag-6 data acquisition and power supply units.
4.3. Pre-Installation Tests
Prior to the installation of the system, the sensor, cable and power supply must be fully tested to
ensure correct function as follows:
Caution:
Take care to avoid bending or otherwise damaging the contacts whilst conducting
the tests.
1. Test the cables for continuity (using an electrical continuity tester or ohmmeter).
a. Test the cables end to end at the connectors, to ensure that the correct pins have
been allocated to the conductors and that there are no open or high resistance
circuits.
Note:
Cable resistance will vary: refer to the product brochure for the expected values.
b. Test the cables at the connectors to ensure that there are no short circuits between
the conductors.
2. Check the power supply output voltage using a voltmeter. Refer to the product brochure
for the expected values.
3. Connect the sensor to the cable connector.
4. Connect the power supply to the other cable connector.
4.4. Mounting Recommendations
Each sensor in both packaged and unpackaged versions has a set of mounting holes to allow
attachment to a stable base or fixture. Refer to drawings DR2545 and DR2945 for further
information.
The sensor can also mounted on the Bartington Instruments Mag-TA Universal Tripod Adaptor.
See the product brochure for instructions on how to do this.
