How to use this manual This document describes the installation, operation and maintenance of the Mag585 and Mag592 Magnetic Field Sensors. -
Page 5: Safe Use
The Mag592 is a single axis equivalent, providing precision measurements of the intensity of static and slowly varying magnetic fields in one direction. The Mag585 and Mag592 are cost effective sensors suitable for many general purpose applications. High stability circuitry ensures that a minimum of ten years’ service should be expected. -

The point of each vector arrow indicates the positive direction of each axis. 5. Installing the Mag585 and Mag592 5.1. Siting the magnetometer (environment recommendations) Note: Site the magnetometer several metres from any magnetic base rock to avoid compromising measurements. -

5.2.3. Power supplies The Bartington PSU1, Magmeter, SCU1 and Spectramag-6 are ideal power supply units. Alternatively, users may wish to provide their own power supply. Refer to Appendix 1 for further information. -
Page 8: Mounting Recommendations
BARTINGTON INSTRUMENTS Caution: Switch off the power supply before connecting to the Mag585 and Mag592. 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. -
Page 9: Connecting Power
The output from all fluxgate sensors will contain noise from the driving electronics. For the Mag585 and Mag592 this noise is at 12.8kHz, which is well above the bandwidth of the sensors. Where low noise operation is required, a filter should always be provided to reject the noise which lies outside the band of interest. -

Caution: Exceeding the maximum ratings may cause irreparable damage to your sensor. 7. Troubleshooting The Mag585 and Mag592 are unlikely to suffer any defects in normal use. The most likely causes of failure, and their solutions, are detailed in the following table:... -

8.1. Cleaning the Mag585 and Mag592 Use water and mild soap to remove grime from external enclosures. Caution: Never use chemicals, such as solvents, when cleaning the Mag585 and Mag592. Caution: Take particular care when cleaning around electrical connections. Bent or damaged pins may cause the magnetometer to malfunction. -

Appendix 1: Use of Alternative Power Supplies Bartington Instruments power supplies provide the most suitable methods for connecting to and operating your sensor. If you have decided to use an alternative then the information in this Appendix is important. -
Page 13: A1.1. Signal/Power Ground
BARTINGTON INSTRUMENTS The current drain is independent of the power supply voltage, and the unit will operate with input voltages down to ±8V. As the output voltage swing is limited to 2V less than the supply voltage, for a supply of ±8V the output will operate normally with any output between +6V and -6V, representing a field of 0.6 of the full scale value in each direction. -
Page 14: A1.2. Recommended Connection Method
Host Local 0V Figure 2 illustrates the recommended connection method for users who do not wish to use Bartington Instruments’ power supplies. Note: Using this method is essential when using cables over 10m. The schematic shows signal and power grounds separated at the Host end. The Host is fitted with buffer amplifiers configured as Instrumentation Amplifiers (IA), which have two high impedance inputs, one connected to X, Y or Z and the other to signal ground. - Page 15 BARTINGTON INSTRUMENTS In this configuration there is a voltage drop due to the cable’s resistance along the power ground. Typical current is 25mA and the resistance of a 100m, 24 AWG cable is 5Ω, resulting in a drop of 0.125V. Thus the reference point for the X, Y and Z outputs is 0.125V difference to the Host 0V, which is the source of power for the sensor.
