Pre-Installation Tests; Mounting Recommendations - Bartington Mag690 Operation Manual

The Bartington PSU1, Magmeter, SCU1 and Spectramag-6 are ideal power supply units.
Alternatively, users may wish to provide their own power supply.
information.

4.3. Pre-Installation Tests

The Mag690FL allows users to select their preferred connector.
Caution: Ensure any crimp terminals are the correct size for 7 x 0.2mm / 24AWG wire.
Prior to the installation of the system, the magnetometer, cable and power supply must be fully
tested to ensure correct function as follows:
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.
b. Test the cables at the connectors to ensure that there are no short circuits between the
conductors.
Caution: Take care to avoid bending or otherwise damaging the contacts whilst conducting
the tests.
Caution: Carefully check for correct connection before applying power. Applying incorrect
polarity or power to output connections may cause irreparable damage to the sensor.
2. Check the power supply output voltage using a voltmeter. Refer to the product brochure for
the required values.
Caution: Switch off the power supply before connecting to the Mag690.
3. Connect the magnetometer to the cable connector.
4. Connect the power supply to the other cable connector.
5. Switch on the power supply and wait until the magnetometer has stabilised. Refer to the
product brochure for warm-up times.

4.4. Mounting Recommendations

Each magnetometer has a set of mounting holes to allow attachment to a stable base or fixture.
Refer to the mechanical drawings on the product page for details.
The sensor can also mounted on the Bartington Instruments Mag-TA Universal Tripod Adaptor.
See product brochure datasheet DS3140, available from Bartington Instruments, for instructions
on how to do this.
