10.2.2 Standards for LF probes
For the LF probes, the standard is used to display the limit curve graphically in the spec-
trum or to display the measurement result as a normalized spectrum. The selection is
made under
MEASUREMENT SETTINGS
>
Standard
. The same table applies as for
HF probes. The selection
None
is used to switch off the display of a limit value curve in
the
SPECTRUM
operating mode.
10.3 Offset correction – Zero
⇒
See measurement settings in the operating modes.
Manual offset correction is only required for the HP-01 probe. The correction process is
started by triggering
Zero
in the measurement settings and is recommended before mea-
suring small static fields. For offset correction of the HP-01, the sensor tip must be placed
in a zero field chamber before the correction process is started, in order to exclude the
influence of external fields and especially that of the earth's magnetic field.
Perform the offset correction:
1.
Press
SK2
, then select
Zero
.
↳
A dialog box opens.
2.
Follow the instructions in the dialog box.
3.
Continue with
SK4
or cancel with
SK1
.
↳
The progress and completion of the offset correction are displayed.
4.
Follow the instructions in the dialog box.
5.
Press the
Back
key to return to the measuring mode.
