Specimen

In this tab, set the number of concrete samples (specimens) to be measured, their dimensions, the length of the traverse lines and their layout over the specimen. When you press the EN 480-11 button, values which are needed to fulfill this Euronorm requirements will be set.

Number of specimens

Specifies the number of samples to be measured.

Length (Y Axis)

Specifies the length of the specimen.

Width (X Axis)

Specifies the width of the specimen.

Non-metering margin (top/bottom)

Specifies the top and bottom non-metering margins of the specimen.

Non-metering margin (left/right)

Specifies the left and right non-metering margins of the specimen.

Volume paste content

Specifies the percentage of the volume paste present in the specimen.

Total length of the traverse line

Specifies the total length of the traverse line.

Line spacing

Specifies the spacing between the traverse lines.

Number of lines on margins

Specifies the number of lines on margins.

EN 480-11

Sets all the specimen parameters according to the Euronorm EN 480-11.

Measurement

Editing method of the detected air voids, XY stage settings, automatic focusing method, and the result filtering parameters can be adjusted in this tab.

Line editing method

Classic

• Left mouse button marks the beginning and the end of a line section. This section will be erased.

• Left mouse button + Ctrl marks the beginning and the end of a new air void.

CAD system

• Left mouse button marks the beginning and the end (left to right) of a line section of a detected air void. This section will be erased.

• Left mouse button marks the beginning and the end (right to left) of a new air void.

XY Stage

Check Manual XY if you use a manual XY stage.

To measure only along the X axis, check Measurement along X.

Check User-defined XY scanning start position to set a new scanning starting position based on the current stage coordinates. Click Define... to set the new scanning start position. To move the stage to this position, click Move to....

Focusing

When scanning a concrete sample, the system focuses repeatedly every n-th frame (n=step). If the concrete sample is well prepared (perfectly flat with constant thickness), you can set the step to 5 or higher. To use auto focus, first Learn autofocus. For manual focusing, check Manual focus.

Filtering

Cleaning factor [microns] specifies the minimal size of the detected air voids in micrometers. Air voids smaller than that will be omitted. On the contrary, if an empty space between two air voids is smaller than the Filling factor [microns] value, the two air voids will be merged into one.

Note

The Cleaning factor is applied first.

Classifier

Select a classification method of evaluating the binary objects. Neural Network defines the classes via neutral network algorithm from the defined samples. If Bayes is selected, classes are defined via an algorithm for calculating classes from the defined samples. Approximation of detected air voids with inscribed circles speeds-up the classification.

Report

At the end of each measurement task, a report is created containing the measurement results. The report consists of several files, all placed into the Root directory. Here you can specify the destination file names.

Root directory

Directory where the report files will be placed.

RTF template

Path to a predefined .rtf template.

XLS template

Path to a predefined .xls template.

Report name, .rtf

Specifies the name of the .rtf file.

Report name, .xls

Specifies the name of the .xlsn file.

Data export, .txt

Specifies the name of the .txt file.

Histogram name, .bmp

Specifies the name of the histogram .bmp image.

Store album of air voids

Stores an image file containing the album of detected air voids. Each measurement frame is cropped so only a thin stripe containing the traverse line remains. These stripes are stitched together, labeled and saved to the album file. Measurement results can be verified visually using this image.

Album name, .bmp

Specifies the name of the album .bmp image.

Lines

Graphic properties of the annotation objects used during the measurement can be set here.

Traverse line

Color and width of the traverse line can be adjusted here.

Chord

Color and width of the chord can be adjusted here.

Help lines

Color and width of the help lines can be adjusted here.

Classifier

Color of the air voids and paste can be changed here.

Small air void highlighting

Voids smaller than the specified size can be highlighted with a selected color, width and length. Just check Highlighting voids less than [in microns] and adjust the parameters.

Other

Do not show error if the Z drive is not present

If the motorized Z drive is not present in the system, an error message appears whenever the stage is being initialized. Here you can suppress this message.
