Using the Bartington MS2 Magnetic Suceptibility Meter for Field Surveys

1. Assemble the probe. The extending handle is used for field surveying. The probe can be either the circular (annular) head or the pointed probe tip. The annular head is best, because it is relatively sturdy and under good field conditions gives a reproducible measuring position. The pointed tip may be better in long undergrowth or for spot surveys where reproducibility is less important. Ensure the connections to the panel on the handle are made correctly or the instrument may be damaged. The connectors for the lead to the probe and the lead to the meter are clearly marked. Connecting the BNC connector to the annular head on the Earth Sciences MS2 (but not the HISAR one) involves the use of a threaded connector. This is a small component - make sure it doesn't get lost!

2. Prepare the instrument by switching to SI units and selecting an appropriate scale. Switching the scale control round to Batt. gives a readout on the small dial of the state of the batteries.

3. Zero the instrument by holding the search coil in the air away from any objects, and moving the mode switch to the right to the "Z" position. Move it back to the left "M" postion ofr measuring.

4. Take measurements as required. Check for drift by holding probe away from the ground and taking reading. Re-zero and log these measurements as required.

5. There is no data-logger for this instrument, so you simply write down the results!

6. Remember that the instrument only measures within approximately 20 cm of the search coil. This means it is relatively free from problems due to fences etc. The only significant problem so far recorded in field use, is a relatively rapid drift.
