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).
