Between the units and their multiples there are the following relations:
Magnetic Flux Density
B
:
Magnetic Field Strength
H
:
1T = 1000 mT
1 T = 10000 G
1 kG = 1000 G
1 G = 0.001 kG = 0.0001 T
1 kA/m = 1000 A/m = 10 A/cm
1 A/m = 0.001 kA/m = 0.01 A/cm
1 A/cm = 0.1 kA/m = 100 A/m
1 Oe = 0.001 kOe
1 A/m = 4

The relation between the magnetic flux density
B
(in Tesla) and the magnetic field strength
H
(in A/m) is given by the following relation:

Here
µ

is the magnetic field constant or permeability of the vacuum.
If the unit for the measurement is changed, the relative and limit set points and stored measured
values are automatically converted to the new unit.

Filter Menu
The
Filter
function averages several sequential field readings (moving average). It is used to
quiet the display, making it more readable when the probe is exposed to a noisy field.

Filtering slows down the reaction on changes of the field strength. Therefore care must be
taken, especially if filtering is used together with the
Max./Min.
function.
