Standard Packing List

6.3.1 Introduction to Measurement Toolbar

The Measurement Toolbar will pop up when moving the mouse to any place near the upper side of the video window. Here is the introduction of the various functions on the Measurement Toolbar:

Make Calibration to determine the corresponding relation between magnification and resolution; this will establish the corresponding relationship between the measurement unit and the sensor pixel size. The monitor's size can be input to achieve the accurate value of the digital magnification. The Calibration needs to be done with the aid of a ruler with an accuracy of more than 1mm. The detailed Calibration process is described in Sec. 6.3.2.

• Export the measurement information to CSV file (*.csv).
• Delete all the Measurement Objects.
• Setting ❌ Exit from Current Measurement Mode.

When the measurement ends, left-click on a single measuring object and the Object Location & Properties Control Bar (⬅️ ➡️ ⬆️ ⬇️, Color Adjustment, Delete) will show up. The icons on the control bar mean Move Left, Move Right, Move Up, Move Down, Color Adjustment, and Delete.

Note:

1. When the user left-clicks the ?️ Display/Hide button on the Measurement Toolbar, the Measurement Toolbar will be fixed. In this case, the Camera Control Panel will not pop up automatically even if moving the mouse cursor to the left side of the video window. Only when users left-click the ❌ button on the Measurement Toolbar to exit from the measurement mode will they be able to perform other operations in the Camera Control Panel, the Autofocus Control Panel, or the Synthesis Camera Control Toolbar.
2. When a specific measuring object is selected during the measuring process, the Object Location & Attributes Control Bar (⬆️ ⬇️ ⬅️ ➡️) will appear for changing the object location and properties of the selected objects.
3. To ensure accuracy of the measurement, after the calibration is turned on, the camera will automatically reset, and then set the normalization magnification to 18X, and adjust the focus to the required standard object distance. If the "Calibration Object" on the stage is not clear on the monitor, you need to manually adjust the height of the bracket to the clearest position, which is the standard object distance. After the Calibration is completed, use the Measurement Toolbar to measure the 1mm physical distance on the ruler, which should display 1mm on the monitor.
4. Even if the Calibration has been completed and the user needs to measure, it is not certain that the microscope is at the standard object distance position that was used for the calibration. ALWAYS reset the microscope height to correspond to the height used for the calibration, then ensure the sample is clearly in focus prior to making measurements.

6.3.2 Calibration Method

User needs to prepare a Calibration Object such as a ruler before Calibration.

Move the mouse to the upper side of the video window; the Measurement Toolbar will appear. Clicking ⚙️ Calibration on the Measurement Toolbar to start the calibration.

1. The built-in software will pop up a message box: "1. Camera resetting for calibration...".
2. After the reset is finished, a message box: "2. Please put the calibration object on the stage (if not), adjust the height of the stand until the calibration object is in focus, then click OK button;" will pop up.
3. After clicking the OK Button, the built-in software will pop up a Calibration dialog shown below:

• Magnification: The Magnification edit box, can be set from 1 to 18 as the user wants. Click the Apply button to confirm.
• Actual Length: The Actual Length of the Calibration object on the stage. The unit can be selected with the right drop-down list box. Read the hint on the Calibration dialog to get the correct Calibration result.
• Monitor Size: The Monitor Size in Inch for the magnification calculation of the object displayed on the monitor.
• Pixel: The length in Pixel of the Calibration Line on the monitor.
• Resolution: The resolution in Pixel/Meter unit which is arrived by Pixel/Actual Length.
• OK: Click the OK button to end the Calibration.

Users can refer to the message: "3. Please adjust the length and position of the calibration line until it is aligned with the calibration object. Then write down the actual dimension of the calibration object in the "actual length" edit box, and click OK." to get the correct calibration result.

The default monitor size is 27.0 inches. Users can enter the Monitor Size for the monitor in use.

6.4.1 Setting>Network

6.4.2 Setting>Measurement

This page is used for defining the Measurement Object properties.

• Global: Used for setting digits behind the decimal point for measurement results.
• Line Width: Used for defining the width of the lines for calibration.
• Color: Used for defining the color of the lines for calibration.
• EndPoint: Type: Used for defining the shape of the endpoints of lines for calibration: Null means no EndPoint, rectangle means rectangle type of endpoints. It makes alignment more easily.

Point, Angle, Line, Horizontal Line, Vertical Line, Rectangle, Circle, Ellipse, Annulus, Two Circles, Polygon, Curve

Left-click the ➕ along with the Measurement command mentioned above will unfold the corresponding attribute settings to set the individual property of the Measurement Objects.

6.4.3 Setting>Magnification

This page's items are formed by the Measurement Toolbar's Calibration command.

• Name: Names such as 4X, 10X, 18X are based on the magnification of the digital microscopes.
• Resolution: Pixels per meter. Image devices like microscopes have a high Resolution value.
• Clear All: Click the Clear All button to clear the calibrated magnifications.
• Delete: Click Delete to delete the selected magnification.
• Up: Select a row in the magnification ratio and click Up to move up the currently selected magnification ratio.
• Down: Select a row in the magnification ratio and click Down to move down the currently selected magnification ratio.

6.4.4 Settings>Image Format

Image Format:

• JPEG: The extension of JPEG files can provide very high compression rates and display very rich and vivid images by removing redundant images and color data. In other words, it can achieve better image quality with the least disk space. If measurement objects are available, the measurement objects will be burned into the image, and the measurement cannot be edited.
• TIFF: TIFF is a flexible bitmap format mainly used to store images including photos and artistic images.

Measurement Object Saving Method:

• Burn in Mode: The measurement objects are merged into the current image. User cannot edit the measurement objects anymore. This mode is not reversible.
• Layered Mode: The measurement objects are saved in a different layer with the current image data in the target file. User can edit the measurement objects in the target file with some software on the PC. This mode is reversible.

6.4.5 Setting>Video

• Video Playback: Fast Forward/Reverse interval in seconds for Video Playback.
• Video Encode: Select the Video Encode format. Can be H264 or H265. Compared with H264, H265 has a higher compression ratio, which is primarily used to further reduce the design flow rate, in order to lower the cost of storage and transmission.

6.4.6 Setting>Storage

List the file system format of the current storage device.

• FAT32: The file system of SD Card is FAT32. The maximum video file size of a single file in FAT32 file system is 4GB.
• exFAT: The file system of SD Card is exFAT. The maximum video file size of a single file in exFAT file system is 16GB.
• NTFS: The file system of SD Card is NTFS. The maximum video file size of a single file is 2TB.
• Unknown Status: SD Card not detected or the file system is not identified.

Note: For USB Flash Drive, USB 3.0 interface is preferred.
