Operation
Fast Transients
In the transient menu, you have the option to delete, start, or show a transient . There are two memory locations available
to record transients,
TRANSIENT NO.1
and
TRANSIENT NO.2
. Before a new transient can be started, one must be deleted from
the memory by pressing
OK
at the
TRANSIENT DELETE
prompt . Each transient contains a maximum 240,000 samples . For
example, with a sampling rate of 1 ms the memory capacity is 240 seconds in each memory location . Press
OK
to begin
recording, the minimum recording time is 30 s . To stop recording, press and hold
OK
for at least five seconds, D
ATA STORED
is
automatically displayed .
TRANSIENTS
NO. 1 DELETE
Recorded data, in the transient 1 memory location, is deleted by pressing
OK
at the
TRANSIENT NO. 1 DELETE
prompt . The unit will display
ERASE DATA?
Press
OK
again to
confirm the request . The screen will display
DATA ERASED
.
TRANSIENTS
NO. 1 START
Data recording, in the Transient 1 memory location, is started by pressing
OK
at the
TRANSIENT NO. 1 START
prompt . The screen will display
TRANSIENT STORED
until the storage
session is stopped . To stop the transient, press and hold
OK
after the minimum recording
time of 30 seconds . The display will show a graph of the data .
This prompt will not display if a transient is currently stored on the device at that location .
TRANSIENTS
NO. 1 SHOW
A graph of the transient 1 data is displayed by pressing
OK
at the
TRANSIENT NO. 1 SHOW
prompt, see
This prompt will not display if there is not a transient stored on the device at that location .
OTEE:
N
The controls for transient 2 work the same way as the controls for transient 1 .
The
SHOW
selection displays the stored measurements as graphs . The X-axis shows the elapsed recorded
time, the Y-axis shows 0…100% of the full scale pressure set in the pressure channel P1 parameter setup . See
"Scaling for Pressure Sensors" on page 11
. Any recording may be stopped by pressing
OK
before reaching the end of the 240
second maximum record length .
