Defining Sample Rate and Positioning
Pressing the [F4] key sets the rates at which the samples are taken. This data field
is then modified in the same manner as the trigger data is entered. Rates can be set
from 0 msec (collect as fast as possible) to 20.000 seconds.
When samples are collected, part of the buffer will store values prior to the trigger
point and the remainder of the buffer will store values after the trigger. Pressing
the [F5] key will allow you to set the percentage of the trend buffer, allocated to
values collected, after the trigger has occurred. This data field is modified in the
same manner as the trigger data is entered.
Starting the Trace
The changes do not take affect, and the trend is not started until you press [F10]
and exit the screen. Any time prior to this you may cancel all the changes made
after coming to the screen by pressing the [F7] key.
When you exit the screen, the trend is started and the screen such as
will show the trigger condition and the status. Pressing the [F7] key on the
DIAGNOSTICS screen may also start the trend.
