Trigger is switched on if one of its six available modes is selected in the Trigger position: Slope +, Slope –,
Level +, Level –, Grad + or External. When the trigger is On, additional parameters can be defined: the
measurement result that is checked for a trigger condition (Source), its threshold level (Level) and the speed of
its changing (Gradient).
Slope type trigger
The Slope + trigger starts the measurement/integration with the duration of the
Integration Period under the condition: rising value of the RMS result (Source)
integrated during 0,5 ms passes above the threshold level (Level).
When the new measurement cycle begins (after pressing the <Start> key or automatically after the stop of the
previous measurement cycle) the instrument checks the trigger condition every 0.5 ms and if condition is met the
instrument starts the continuous series of 1-second integrations, the number of which is equal to the number of
seconds in the Integration Period.
After elapsing the Integration Period, the new
measurement cycle can start with above logic.
The measurement can be stopped manually at
any moment with the <Stop> key.
The Summary Results are calculated on the
base of series of 1-second results measured
during each measurement cycle and saved in
the results file.
The Slope - trigger starts the measurement/integration with the duration of the
Integration Period under the condition: falling value of the RMS result (Source)
integrated during 0.5 ms passes below the threshold level (Level).
This is a mirrored trigger to the Slope + trigger.
Note: When a measurement is waiting for the slope trigger, the
“slope” icon appears alternatively with the „measurement” icon.
Level type trigger
The Level + trigger starts the 1-second measurement/integration under the
condition: value of the RMS result (Source) integrated by 0.5 ms is greater than
the threshold value (Level). In other cases, the instrument continues checking
the trigger condition every 0.5 ms.
When the new measurement cycle begins (after pressing <Start> key or automatically after the stop of the
previous measurement cycle) the instrument checks the trigger condition every 0.5 ms and starts 1-second
integration if condition is met.
