After 1-second integration, the instrument
repeats the trigger condition checking every 0.5
ms and starts next 1-second integration if
condition is met. Instrument does it as many
times as many seconds are within the
Integration Period and stops the
measurement cycle. Therefore, the series of 1-
second measurements may not be continuous,
as it is in case of the Slope type trigger and the
duration of the measurement cycle can be
longer than the Integration Period.
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 Level - trigger starts the 1-second measurement/integration under the
condition: value of the RMS result (Source) integrated during 0.5 ms is lower
than the threshold value (Level). In other cases, the instrument continues
checking the trigger condition every 0.5 ms.
This is a mirrored trigger to the Level + trigger.
Note: When a measurement is waiting for the level trigger the “level”
icon appears alternatively with the „measurement” icon.
Gradient type trigger
The Grad + trigger starts the 1-second measurement/integration under the
condition: value of the RMS result (Source) integrated during 0.5 ms is greater
than the threshold level (Level) and the gradient of this Source is greater than
the gradient threshold level (Gradient). In other cases, the instrument continues
checking the trigger condition every 0.5 ms.
This type of trigger has the same logic as Level + trigger, but the trigger condition requires also the gradient
threshold level to be exceeded.
External trigger
When External is selected, the measurement is triggering by the external signal
on the I/O socket. In this case, it is necessary to set up the I/O Mode parameter
as Digital In (path: <Menu> / Instrument / Multifunction I/O).
After the measurement/integration start from the external trigger, the
measurement/integration will continue for the Integration Period.
Note: When a measurement is waiting for the gradient or external
trigger the “trigger” icon appears alternatively with the „measurement”
icon.
Trigger source
Only one measured result can be used as a trigger source (Source) for checking of the trigger condition in the
Level Meter mode, namely the output signal from the RMS detector coming from the first profile which is denoted
here as Leq(1) in the sound mode and RMS(1) in the vibration mode. This position does not become active (it is
not displayed inversely) and the text stated here remains unchanged.
