•
in the case of Level – is selected, the triggering condition is fulfilled only when the Source has the
lower value than this determined in the Level position and in the other cases the triggering condition is
not fulfilled.
•
in the case of Slope + is selected, the triggering condition is fulfilled only when the arising value of the
Source is passing the level determined by the Level parameter.
•
in the case of Slope – is selected, the triggering condition is fulfilled only when the falling down value
of the Source is passing the level determined by the Level parameter.
•
in the case of Gr is selected, the triggering condition is fulfilled only when the signal has the
greater level than this determined in the Level and the gradient of the signal is greater than this
determined in the Gradient position. In the other cases the triggering condition is not fulfilled.
•
in the case of Gradient - is selected, the triggering condition is fulfilled only when the signal has the
lower level than this determined in the Level and the gradient of the signal is lower than this
determined in the Gradient position. In the other cases the triggering condition is not fulfilled.
Step for checking the triggering
condition
The Trig. Step position enables one to
select
integration time for condition
evaluation: Logger step, 100ms, 1.0s,
Meas. Time and Meas. Period.

Source for triggering condition and
channel of triggering signal
The Source position enables one to select
the type of source for triggering condition
calculation: Vector or Profile 1.
The Channel position enables one to select
the channel of triggering source. Depending
on value of the Source parameter, the
value of Channel will be different.

Function for triggering condition definition and threshold
The Result position enables one to select the function for triggering
condition: PEAK, P-P, MAX, MIN, RMS or VDV. When Vector is selected
as a Source the only one function is available – RMS.
The Level position enables one to select the value of threshold for
triggering condition. The level of the triggering source can be set in a range
from 60 dB to 200 dB or from 1.00 mm/s
2
to 10.0 km/s

, depending on
what scale type was selected in the Scale position (path: <Menu> / Display
/ Results Scale).
Speed of the triggering signal change
This position appears when the Gradient - or Gr trigger is chosen.
The speed of the triggering signal changes (Gradient) can be set from 1 dB
to 100 dB range. Speed is defined as dB per Logger Step.
