Example of an Automatically Triggered
Measurement
The following occur in a hydraulic press from
time to time: defective components, ruptured
hoses or cracked cylinders. You suspect
there may be extremely high pressure peak-
ing in three hydraulic circuits and want to
monitor the press for pressure surges for an
extended period of time.
To do this, you make the following settings:
•
Recording:
Measurement curve with trigger
•
Channels:
A, B, C
•
Sampling rate:
1 ms
•
Recording time: 30 seconds
Trigger settings:
•
Event 1: channel A increases to 180 bar
•
Event 2: channel B increases to 230 bar
•
Event 3: channel C increases to 280 bar
(Each of these pressures is 50 bar higher
than is normally allowed.)
•
Pre/post trigger: 80 / 20%
(You select this option because you are
interested in knowing what happened in
the other pressure circuits before the trig-
ger was actuated and you want to record
the pressure curve somewhat longer after
the trigger event.)
•
Automatic measurement:

bar, in the next screen you are prompted
for a name and number for the measure-
ment. The measurement is then stored un-
der this name with a consecutive number
after every trigger event. You also have the
option of entering a comment, e.g. the operat-
ing condition of the machine.
