filters
High-pass filters may be set from 0 Hz (
OFF
) to 100 Hz in 1 Hz increments, and
from 100 Hz to 1000 Hz in 5 Hz increments. To adjust the
HI PASS
filter settings,
press the MAIN FILTER menu key (
) three times, followed by the A key, and
then rotate the knob to the desired value.
LO PASS
filters
Low-pass filters may be set from 10 Hz to 100 Hz in 1 Hz increments, up to
500 Hz in 5 Hz increments, and up to 2000 Hz in 25 Hz increments, followed by
wide band. To adjust the

filter settings, press the MAIN FILTER menu
key (
) three times, followed by the B key, and then rotate the knob to the
desired value.
CONT NUL
(continuous null)
CONT NUL
allows a very low-frequency high-pass filter to be turned on, which
is useful to keep the null point of the eddy current probe at the specified point, if
required. When turned on, this function adds a 0.2 Hz, 0.5 Hz, or 1 Hz high-pass
filter. By default, this feature is set to
OFF
.
To turn on continuous null, press the MAIN FILTER menu key (
) three times,
followed by the C key, and then rotate the knob to the desired value.
SCAN RPM
(NORTEC 600S and NORTEC 600D models only)
The
SCAN RPM
function controls the scanner rotational speed (revolutions per
minute) when an optional rotating scanner is connected to the NORTEC 600S
(N600S) or NORTEC 600D (N600D) instrument models.
To adjust the
SCAN RPM
setting, press the MAIN FILTER menu key (
