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

When the measurement ends, left click on a single measuring object and the Object Location & Properties Control
Bar 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 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 sets the normalization magnification to 20X, and adjusts 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, once the user needs to measure, but is not sure whether the camera
is at the standard object distance position, it is always better to reset it first, adjust the stand height in the reset state
to see object clear, and ensure that the camera is at the standard object distance position before measurement.
6.3.2 Calibration Method
User needs to prepare a Calibration Object such as ruler before Calibration;
Move the mouse to the upper side of the video window, the Measurement Toolbar will appear. Clicking

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, DeltaPix 4KView will pop up a Calibration dialog shown below:

Userscan 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.

JPEG: The extension of JPEG file can get very high compression rate and display very rich and vivid images by removing
redundant images and color data. In other words, it can get 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.
