7.7.5 Graph screen: recording
Recording is used to store the measurements taken during the test in the control panel memory. It will
not save these measurements.
For each measurement, the leak rate and inlet pressure are recorded.
During recording, all of the leak detector functions are available.
After the detector is turned off (by a power failure or user manual shutdown), the current recording is
cleared.
A record may include several measurements. The successive measurements are recorded one after the
other in the recording: a visual cue (Δ) indicates the measure change.
To start a new recording, you must first save the current one.
When the memory is full and a recording is in progress, recording is automatically stopped.
1. Update the recording settings if necessary (see chapter "Graph screen: graph parameters").
2. Press [COMMENT] to add a comment (see chapter "Graph screen").
●
Optional: this comment can be added at any time during the recording or during a pause
●
Comments can be viewed later in the backup .CSV file.
3. Press [START REC] to start recording.
●
[START REC] is replaced by: [STOP REC], [STBY REC] and [COMMENT].
●
Total recording duration: a flashing round dot is displayed, indicating that a recording is in
progress.
●
None of the measurements displayed on the plot before the recording starts will be recorded.
4. If necessary, press [STBY REC] to pause.
●
The pictogram glows red without flashing.
Total recording duration: the red dot is steady, indicating that the recording is paused.
●
None of the measurements displayed on the plot during the pause will be recorded.
5. Press [STBY REC] again to re-start recording.
6. Repeat the previous steps as many times as necessary.
7. Press [STOP REC] to stop recording.
●
Return to the recording in progress to continue (the measures already saved will be retained):
press [<] then [START REC].
●
To stop and save the recording in progress: press [STOP REC] (see chapter "Graph screen:
saving a recording").
7.7.6 Graph screen: graph history
The Graph history automatically records a history of the leak rate and inlet pressure values once the
leak detector is on. It is not the user who triggers recording of the history. They do not save these val-
ues.
The history recording continues even when the user has started a recording (see chapter "Graph
screen: recording").
The history is recorded in the leak detector’s buffer memory.
The maximum duration of the history recording depends on the current setting:
●
12 s display time: 60 min history recording
●
1 h display time: 298 h history recording (≈ 12.4 days)
►
Double press on the graph screen to view the Graph history.
The user can save the recording of the history: see chapter “Graph screen: save”.
The user can zoom in on the recording of the history: see chapter “Graph screen: viewing”.
The user can view the details of each point in the history recording: see chapter “Graph screen: view-
ing”.
7.7.7 Graph screen: save and delete
The user can save the following recordings:
●
recording in progress (see chapter "Graph screen: recording").
●
graph history recording (see chapter “Graph screen: graph history”)
It is saved in the form of a file (.csv) or a screenshot (.png)
Saving is not automatic.
