User Trigger Parameter Definitions
Input Signal.
Consists of the measured signals and parameters, such as Voltage, Current, Watts,
VARS, which are compared to the limit.
Channel.
The phase of input signal, noted as A, C, B and Ave, or other values, such as frequency
or phase deviation, as uniquely required.
Limit Type.
The logical condition used to compare the Limit and the Input Signal (
x
);
x > limit
,
x < limit
,
|
x
|
> limit
,
|
x
−
ref
|
> limit
.
Limit.
A floating point value to which the Input Signal (x) is compared.
Reference.
A floating point value used with the Limit Type,
|
x
−
ref
|
> limit
, for the value of
“ref”. Can be used in a window comparison.
Dependency.
Selects the Master Trigger state. Values are Off, ActiveMaster, InactiveMaster;
“Off” turns off the Master Trigger feature. Use the other two values to set up the Master Trigger
condition.
Master.
Assigns the specific Trigger number (1 - 32) as the Master Trigger. Set up the Master
Trigger
prior to
the dependent trigger or the Master Trigger number will not be available.
Dwell Time.
Defines the interval in seconds during which the measured signal meets the triggering
condition (i.e true) before the trigger becomes Active.
MaxLogTime.
Sets the time in seconds that the 1133A will log data after the trigger becomes
Active. Time is from 0 to 65535 seconds.
PostFault.
Sets the time in seconds that the 1133A will log data after the trigger has become
Inactive. Time is from 0 to 65535 seconds.
