| Special software SUFAR
combines the measurements in three perpendicular planes
to create a complete susceptibility tensor. The errors in
determination of this tensor are estimated using a
special method based on multivariate statistics
principle. The KLY-4S Spinner
Kappabridge can measure, in the spinner mode, specimens
25.4 mm in diameter and 22 mm in height, or cubic
specimens with an edge of 20 mm, or smaller cylindrical
or cubical samples that can be encapsulated into a
perspex cylinder or cube of the above dimensions.
| However, to measure
specimens with slightly different shapes (e.g.
ODP type specimens), KLY-4S Kappabridge should be
operated in the manual |
 |
non-spinner static mode using the
same static 15 position measurement technique as with the
KLY-4 Kappabridge. This optional non-spinner static mode
can also be used for measuring the bulk susceptibility of
rock fragment specimens.
KLY-4 Kappabridge
Static only version
Laboratories under budgetary
constraints may prefer the lower priced static only KLY-4
Kappabridge. In contrast to the KLY-4S spinner/static
version, the KLY-4 measures the AMS of only a static
specimen in exactly the same way as originally developed
for the KLY-2 Kappabridge. The specimen susceptibility is
measured in 15 different positions following rotatable
design. The positions are changed manually and, by using
the included special software package SUFAM, the
susceptibility tensor is calculated including the
statistical errors of its determination.
The restricted capability of the KLY-4 to make
measurements only in the static mode can be upgraded
later to incorporate the more rapid KLY-4S spinner
technique.
