Start measurement process
First connect the input signals with the analog or digital inputs. The measurement can
be started in two ways:
6.3.1
Start measurement process manually
The manual measurement process is started and stopped by briefly pressing the S11
key. Proceed as follows:
1.
Switch the device on by briefly pressing the S11 key. All LEDs initially light up in red,
once the device is ready L1 lights up orange.
2.
Start the measurement by briefly pressing the S11 key. As long as the measurement
process is running, the L1 will flash in green.
3.
You can stop the measurement by briefly pressing the S11 key again. L1 lights up
orange.
6.3.2
Start measurement process triggered
If the measurement process should be started via a trigger signal, then it must be entered
in the configuration file "config.ini":
Configuration for "trigger": [highPulse]
The measurement process only takes as long as the trigger signal is pending (digital
signal, start trigger increasing flange, stop trigger decreasing flange). The trigger signal
must be pending at least as long as the configured sample rate in order to start the data
recording.
The trigger signal connection is described in chapter 5.4.4
Proceed as follows:
1.
Switch the device on by pressing the S11 key for a longer period. All LEDs initially
light up in red, once the device is ready L1 lights up orange.
2.
Go to the "wait for trigger" state by briefly pressing the S11 key. L1 lights up green.
3.
L1 flashes green when the trigger signal is pending and the measurement starts.
Data is only saved while the trigger signal is pending.
4.
Once the trigger signal is no longer pending, the measurement is ended and L1 lights
up green.
5.
To leave the "waiting for trigger" state, briefly press S11.
Note
During each measurement a new measurement file is created. During long-term record-
ings new measurement files are automatically created after every 100,000 samples.
Once the free memory space on the internal memory falls below 40 MB, the measure-
ment data recording is automatically aborted. This is indicated by the LED L1 flashing
red. In addition, an error message file "Error.log" is stored in the "log" directory with the
following content: „[ERROR] stopped measuring --> running out of disk space“.
