Description of user interfaces

The microscope has several user interfaces. These can be opened by moving the mouse to the left or bottom edge of the screen.

Menu screen left

Click to take a picture. The screen displays a message with the file name.

Hint

Dimension lines and drawing elements are not included in the image.
Click to start and stop a video recording. After the recording has started, a time indication starts in the upper right corner of the display indicating the recording time.

File overview

Shows the existing image and video files in a side view.
The navigation through the file overview is explained in chapter 6.1.1.

Drawing menu

In the drawing menu, you will find shapes and operations for measuring the image, explained in chapter 6.1.2, and the calibration menu, explained in chapter 6.1.3.

Settings menu

Options for the image settings and other system settings such as date and time settings.

File overview

The file overview shows images and videos recorded on the SD card.
You can switch to the large view of the images with a double click.

Navigation bar

Back button

Exit the file overview or the large view.

Forward / back button

Navigate through the file overview and the large view.

Delete button

Delete the displayed item.
In the file overview, an entry must be selected by a mouse click.

_ Note: _Some characters are placed to indicate distances or areas and are generated based on the stored calibration. The calibration of the PCE-LCM 50 is explained in chapter 6.1.3.

Point

Click to place a point at the current cursor position.

Circle from radius

Select the centre point by a click, then move the cursor to the desired distance for the radius.

Circle from 2 points

Create 2 reference points that lie on the edge of the created circle.

Circle from 3 points

Create 3 reference points. The circle is created so that all 3 reference points are on the circumference.

Distance between two circles

The function measures a distance between two circles which can be created by various sub-functions.

Concentric circles

Create a circle using the circle-from-radius function. Here you can create one or more circles with the same centre point.

Distance between line and circle

Create a circle using the circle-from-radius function. Then select 2 points to create a straight line. The measured distance “LD-X” describes the distance between the straight line and the centre of the circle.

Polygon

Create a polygon with any number of reference points. To finish the polygon, press the right mouse button.

Crosshairs

With one click, you create a reference point with coordinates.

Rectangle

Creates a rectangle from 2 reference points.

Line from several points

Creates a line from several reference points.

Arc from 3 points

Creates an arc from 3 reference points.

Freehand line

Creates a line from cursor movements.

Line

Creates a line from 2 reference points.

Perpendicular lines

First, a line is created.
Subsequently, another reference point is used to create a line that is perpendicular to the first line.

Parallel lines

First, a line is created. Then, with another click, you create the first reference point for the parralel line.
The start of this is oriented towards the cursor position.
With another click, you can finish the line.

Angle measurement

First, a line is created.
Then create another line from the end point. The smallest angle between the new line and the original line is measured.

Text

A text field is created. After this, a virtual keyboard is displayed to enter a text. Finish the entry by clicking on the “Confirm” button.

Sheet export

With this function, you can export the automatically determined dimensions of the drawing elements as a CSV file. This file is saved to the SD card with the corresponding time.

Mouse

Switch to the mouse to make further settings.

Select and delete

Use the option to select a drawing element on the display to delete it.

Delete all

Deletes all drawing elements on the screen.

Screenshot

Calibration

“Add “: Creates a new calibration
“Delete”: Deletes the selected calibration
“Edit “: Edit the calibration
- Adjusting the name, length and length unit

Place a dimensioned object under the microscope, for example a ruler. Open the drawing menu, click on “Add” in the lower area. Select 2 points to set a distance on the display. To open the menu again, move the mouse to the left edge of the screen. Click on “Length” and enter the actual length between the two points. To complete the calibration, click on “Done”.

Note that a calibration is only valid for a certain focus.
If the focus changes, a new calibration is required.

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
