3.6 Editing a Measurement Curve

You have various options for editing and processing a curve. All of the functions for this are

located in the dropdown menu of the “Edit“ dialogue box. “Extract Recording... “ and

“Curve Overlay... “ create a measurement which is filed in the left-hand box when files are

open, the files being named “Recording X“ (x = sequential number). They are not stored

automatically however.

3.6.1 Extract Recording

• To create a copy of the measurement currently open or extract a zoomed portion of the

measurement, click on the “Edit“ dialogue box and select “Extract Recording“ in the

dropdown menu.

• The measurement is filed in the left box of the open files and can now be edited without

any changes being made to the original file.

• You can save this file under a name of your own choosing (see “3.7.2 Save“ or “3.7.3

Save As“).

3.6.2 Curve Overlay

• Overlaying two measurement curves is useful for comparing measurements, e.g. the

measurement of a machine cycle taken three months ago vs. its current condition.

• To superimpose two measurement curves, click on the “Edit“ dialogue box and select

“Curve Overlay“ in the dropdown menu (Note

: possible only for curves with the same

sampling interval.

• The “Wizard for Overlay“ opens in a new window.

• You are now asked to select a 2

recording, i.e. the recording to be used for overlaying

the curve currently open.

• Click on the arrow button to get a list of all open curves recorded using the same

sampling rate.

• To see all the curves possible, click on the arrow button next to the name.

(The list is empty if no curves with the same sampling rate are open.)

• Click on the curve you would like to superimpose, followed by clicking on “Next“ in the

bar at the bottom of the window.

• The second recording is opened in the same window as the original recording and a

prompt for coordinating the time of the second recording appears in the wizard. (Shifting

can only be done along the time axis.)

• The recording can be adjusted roughly using the mouse and clicking on the scrollbar,

keeping the left mouse button pressed, and shifting the recording to the approximate

position desired.

• To position the recording precisely, click on the arrow buttons to the right (<) and left (;)

of the scrollbar until the second recording is positioned as desired.

• To overlay the curves click on “Complete“ in the bar at the bottom of the window.

• Click on “Cancel“ to cancel the overlay.

3.6.3 Time-Shift Channels

• To time-shift one or more channels in a measurement, click on the “Edit“ dialogue box

and select “Time-shift channels“ in the dropdown menu.

• The “Wizard for Time-shifting of channels“ opens.

• Select the channel you wish to time-shift in the dropdown menu.

• The measurement channel can be adjusted roughly by clicking on the scrollbar, keeping

the left mouse button pressed and dragging to the right or the left.

• To position the recording precisely, click on the arrow buttons to the right (<) and left (;)

of the scrollbar or press the right (→) and left (←) arrow keys on the keyboard until the

measurement channel is positioned as desired.
