The
Trigger on Marker
position switches on or off the triggering by marker.

is switched on then event recording will start by
initiation of one of the user controlled markers. Markers for triggering are defined
in the
Markers Setup
window.
In the
Trigger

are available:

Note: When event recording is waiting for the external or integration
period trigger the “trigger” icon appears alternatively with the „note”
icon.
If the
Integr. Period
trigger was defined, the signal is recorded every time the
measurement starts and ended after the
Integration Period
time, defined in the
General Settings
window (
path: <Menu> / Measurement / General Settings
).
The
Source
position indicates the triggering signal source. Only one measured result can be used as a source
of the triggering signal in all modes, namely the output signal from the RMS detector coming from the first profile
which is denoted here as
Leq(1)
for sound and
RMS(1)
for vibration measurements. This position does not
become active.
The level of triggering signal for the event
recording (
Level
) can be set with 1 dB steps in the
range from 24 dB to 136 dB in sound modes and
from 1mm/s
2
(60 dB) to 10 km/s
2
(200 dB) in
vibration
modes.
In
case
of
Vibration
measurements, the level can be expressed not
only in decibels but also in linear units. The
vibration unit scale can be set in the
Display Scale
window (
path: Menu / Display / Display Scale /
Scale
).
