Taking measurements

.

Summary

Taking a reading in the 

S

CAN

 mode (

zero-rea

d method) is a sim-

ple three step procedure:

1

Clear the memory so that no data are stored.

2

Press the R

IGHT

 button while holding the sensor at least 30 

cm from any magnetically susceptible bodies for a free-
space reading (i.e. zero the instrument).

3

Press the L

EFT

 button to start the S

CAN

 mode.

4

A pulsing audio tone indicates that the 

S

CAN

 mode is 

active. Move the sensor slowly along the sample to mea-
sure.

1 In  the  S

CAN

 mode, the displayed data are not stored in 

memory.

2 Beware of temperature dependent drift in S

CAN

 mode! 

Since only one measurement of the free-space frequency 
is used for calculating all the susceptibilities, there is a 
possibility that you may experience a gradual decrease in 
the accuracy of the readings over a period of time. You 
should occasionally stop and restart the S

CAN

 mode.

3 The  S

CAN

 mode is not suitable for precise measurements 

of low susceptibility material.
