4.2.3. Power Supplies and Acquisition Units
The Bartington PSU1, Magmeter-2, SCU1, Spectramag-6, Mag-03DAM and DecaPSU are ideal
power supply units and/or acquisition units. Alternatively, users may wish to provide their own
power supply.
4.4. Pre-Installation Tests
Prior to using the magnetometer, cable and power supply, ensure that system is correctly setup:
1. Ensure that the sensor and cable are properly connected.
Caution:
Avoid bending the cable more than its minimum bend radius.
Caution:
For Mag690FL and Mag690U 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 is suitable for the sensor. Refer to the product
brochure for the required values.
Caution:
Switch off the power supply before connecting to the Mag690.
3. Connect the power supply to the sensor.
4. Switch on the power supply and wait until the magnetometer has stabilised. Refer to the
product brochure for warm-up times.
4.5. Post-Installation Testing
1. After warm-up, monitor the sensor’s outputs and ensure the response corresponds to the
local field.
2. Apply a magnetic disturbance to each axis and monitor axes’ response.
