Drill-core samples –

Similar to the problem for uneven

samples, the curvature of the drill-core samples creates large

geometric errors to the measured susceptibility in older

instruments. You would have to correct the data manually using

special tables calculated for various drill-core diameters.

The

KT-9

automatically corrects the reading since you select the

appropriate core diameter prior to taking measurements.

Fast scanning –

The

KT-9

has an automatic

SCAN

mode to

allow larger areas to be scanned quickly for changes in suscepti-

bility. The scan rate is three readings per second—that’s three

times faster than the

KT-5

Variable audio –

In the scan mode, the

KT-9

has a variable

audio tone that is directly proportional to the measured suscep-

tibility—the higher the tone, the greater the susceptibility. This

allows you to quickly scan a rock surface and visually correlate

areas of varying susceptibility.

Data storage –

Up to 10 readings can be stored in the

KT-9

’s

internal memory. This data is retained even if the unit is pow-

ered off!

Data averaging –

The average of up to the 10 stored read-

ings can also be displayed. This allows for very accurate mea-

surement of uneven surfaces while in the

mode, as well as

improved data quality for smoother surfaces while in the

mode.

External sensors –

The design of the

KT-9

permits the con-

nection of various external sensors to the unit via a special con-

nector. When an external sensor is connected, then the internal

sensor is automatically disconnected.

Digital output to a computer –

The

KT-9

can be connected

to a computer via the serial port and a special cable. The

KT-9

can then be completely controlled from the computer in a spe-

cial

REMOTE

mode. In this mode, the computer can start the

KT-9

and store the measured values in a file. This permits core logging
