30. g frequency For the precision reasons it is recommended to use this default value of the field intensity Additionaly to avoid the possible AMS effects the specimens must be orientated in ex actly the same way during each measurement In the case of the cylindrical specimens it is recommended to measure in vertical orientation so that the cylinder axis is parallel to the axis of the instrument coil Fig 26 on page44 That way you always measure magnetic susceptibility parallel to the cylinder axis regardless of the specimen orientation with respect to that axis this cannot be exactly reached in the perpendicular orientation due to the slight specimen misorientations during each individual measurements When measuring the standard paleomagnetic specimens it is strongly recommended to use the manual specimen holder instead of the Rotator used for the automatic AMS measure ments From our experience it seems that more reproducible results can be obtained using the Up Down mechanism compated with the manual inserting of the specimen holder into the instrument coil 6 1 2 Field dependence of susceptibility When this option is selected a sequence of default field intensities is dis played in the measuring table of the main window Fig 15 To modify the sequence click on the EDIT FIELDS button You may edit the field sequence in the Edit fields window Fig 16 You can use three preset sequences Standard Reduced or Super reduced acce
