Part No.: 669855
Event: Actuation of button/key
This setting is designed to trigger a meas-
urement when a button is specifically ac-
tuated. After starting the recording, you
can trigger measurement by selecting
Trigger
in the function bar (+
OK
).
Event: External signal change
An external signal change means that you
apply a direct current signal to one of the
frequency inputs (I or J)
, e.g. via a button
(
NC or NO contact
). A measurement can
then be started when the voltage is switched
on via an
NO contact
(rising signal edge)
or
NC contact (falling signal edge)
.
In the settings menu (see screenshot), you
specify the
trigger input
under
Input
.
Only
the two digital inputs
I and J
are available
here. Next you set the
Slope
to
rising
or
falling
and confirm with
OK
.
Event: Specific value
Use the trigger event
Specific value
to lo-
cate pressure peaks or pressure troughs in a
machine. Pressure peaks always occur in a
rising direction (measured value increases),
whereas pressure troughs occur in a falling
direction (measured value drops). First de-
termine the measurement channel and sub-
channel for which you wish to set the trigger,
then enter the measured value (via the nu-
merical keypad) at which you want to trigger
a recording. Finally, select the direction
(
From below
or
From above
).
Note:
Sub-channel setting only required for SMART sen-
sors (see Section 6.4) and CAN function (see Sec-
tion 6.5).
