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.
5.4. Mounting recommendations
Each magnetometer has a set of mounting holes to allow attachment to a stable base of fixture.
Refer to the mechanical drawings on the product page for details.
5.5. Post installation testing
1. Site the magnetometer and install the power supply and cabling.
2. Switch on the power supply and wait until the magnetometer has stabilised.
3. Confirm no magnetic objects are moving in the vicinity.
4. Monitor the sensor outputs.
5. Confirm that the sum of the measured magnetic field vectors is similar to the expected local
earth field.
6. Using the Mag585 and Mag592
6.1. Cabling
Note:
The connecting cable to the sensor should be an eight-core screened cable. Two
cores will be used for positive and negative power supply lines, three cores for output
signals, one core for signal common and one for power supply ground. The screen should
be connected to supply ground at the supply end only. The capacitance between cores
should be less than 200pF per metre. A cable with individually shielded cores should be
considered for long cable applications.
Note:
Leads are susceptible to EM interference and should be screened wherever possible.
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.
