B1. Display Setup for measurement: Spectrum / Time waveform
Z
OOM
:Step size when zooming the
X and Y-axis
.
Zoom Mode
: The zoom is made around the main cursor or the gap
between the delta and main cursor.
C
URSOR
: Short cursor or line cursor (
long
);
line type
for the line cursor.
D
IAGRAM
TYPE
: A spectrum can be displayed in a
curve diagram
or a
bar
chart
. A time signal can be displayed in Cartesian coordinates (
X-Y
diagram
) or on a
circular plot
. When taking measurements with
DC coupling, the DC component in the signal can be hidden
(Option: ‘AC only’).
S
UFFIX
FOR
1/1000
OR
1000: Instead of '1/1000' or '1000', the X-axis
can be labeled with the abbreviation 'm' (milli) or 'k' (kilo).
A
MPLITUDE
(
SPECTRUM
): Amplitudes in
RMS
or peak values (
0-peak,
peak-peak
). RMS value of entire spectrum: see p. 4-11.
O
RDER
DISPLAY
(
SPECTRUM
): Scaling of the X-axis in Hz (
No
) or orders
(
Yes
). The shaft RPM must be known (measured or entered).
A
MPLITUDE
SCALING
(
SPECTRUM
): linear or logarithmic (in decibels).
D
EFAULT
DISPLAY
MODE
(
SPECTRUM
): Information that appears in the lower
display field by default (
Max 10, time waveform, band alarms,
frequency marker, trending parameters, cursor coordinates
).
S
PEED
M
ARKER
(T
IME
SIGNAL
): Display of the trigger signals in the
diagram. In the circular diagram, the arrow indicates the direction
of rotation.
C
ONTINUOUS
MEASUREMENT
(
LIVE
MODE
): see section X on page 4-15.
B2. Display Setup for Trend: Spectrum (Waterfall diagram)
C
URSOR
& A
MPLITUDE
: s. section B1; in a waterfall diagram, a
grid
can
be superimposed for easier evaluation of the data.
