Event Recorder
DECS-250
Setup
When oscillography is enabled
A
, each record can consist of up to six user-selectable parameters
B
with up
to 1,200 data points recorded for each parameter. Data log setup settings are illustrated in Figure 80.
A pre-trigger-points setting
C
enables a user-defined number of data points recorded prior to the event
trigger to be included in a data log. The value of this setting affects the duration
D
of the recorded pre-
trigger points, the recorded post-trigger points
E
, and the duration of the post-trigger points
F
. A sample
interval setting
G
establishes the sample rate of the data points recorded. The value of this setting affects
the pre- and post-trigger duration values and the total recording duration
H
for a data log.

C
Pre-Trigger Points:
Adjustable from 0 to 1,199 in increments of 1.
D
Pre-Trigger Duration:
Read-only value based on the Pre-Trigger Points and Sample Interval settings.
E
Post-Trigger Points:
Read-only value based on the Pre-Trigger Points setting.
F
Post-Trigger Duration:
Read-only value based on the Pre-Trigger Points and Sample Interval settings.
G
Sample Interval:
Adjustable from 4 to 10,000 milliseconds in 4 millisecond increments for 60 Hz nominal
generator frequency. Adjustable from 5 to 12,500 milliseconds in 5 millisecond increments for 50 Hz
nominal generator frequency.
H
Total Duration:
Read-only value is the sum of the pre- and post-trigger duration values.
