Keep these instructions in a safe place and pass them to any future user. 1.1 Intended use LED-Panel V5 is designed to perform timing measurements on digital cameras. Measurements according to ISO 15739 are possible with LED-Panel V5. •...
1.2 Foreseeable missuse 1.2.1 Older LED-Panel verisons Most parts of this manual apply to LED-Panel V4. Please contact Image Engineering to request a manual from a previous version of the LED-Panel. 1.3 General safety information Do not open the device without any instructions from the Image Engineering support or when connected to the power supply.
3 OPERATING INSTRUCTIONS HARDWARE 3.1 Set up hardware Connect the power cord to the power supply on LED-Panel V5. Connect the power supply to electricity. Switch on LED-Panel V5 by setting the power switch to “I.” The power switch is located beside the power supply.
LED “600” in the lower row. The LED-Panel V5 can be operated manually or via software (USB interface). Please refer to chapter 3.3 for information about control software. 3.2.1 Trigger mode The LED-Panel V5 can be operated manually using either an external (single) or internal (continuous) trigger.
The brightness of the display can be modified by using the rotary knob. Press and hold the rotary knob until the message "Set brightness" and "LED xx LCD xx" are shown on the display. Seite 8 von 45 Image Engineering...
Due to the two buttons having different release points, a time lag can occur between starting the LED-Panel and releasing the camera. We offer an optional device that is guaranteed to push both buttons (microswitch and camera release button) in less than 5 ms. This device – iQ- Seite 9 von 45 Image Engineering...
The autofocus time can be calculated as the difference between shutter lag with autofocus time (Figure 4) and shutter lag without autofocus time (Figure 3). Autofocus time = (shutter lag with autofocus time) – (shutter lag without autofocus time) Seite 10 von 45 Image Engineering...
Exposure times of cameras can be measured with the aid of the LED-Panel. When setting the LED-Panel to CONTINUOUS trigger mode and adjusting the time, a picture of the LED-Panel is taken. The exposure time can be read by analyzing the lit LEDs. Seite 11 von 45 Image Engineering...
LEDs stops blinking on the camera display. The LED-Panel has now matched the frame rate of the camera. The manual frequency scan should be started at the lowest level because the frame rate frequency harmonics also cause the LEDs to stop blinking. Seite 12 von 45 Image Engineering...
Afterward, pictures of the LED-Panel are taken in multi-shot mode. The speed of multi- shot mode can be calculated from a distance between the live LEDs in two consecutive images. Figure 8 Figure 7 Seite 13 von 45 Image Engineering...
The time can be read from this offset, which is required to read out the LED-Panel image. For this measurement, we recommend framing the field of the LEDs in the image so that they fill the whole image height. Seite 14 von 45 Image Engineering...

Unless you changed the default installation path, you will find the directory “Image Engineering\LED-Panel <version number>” in your “Program Files” folder after a successful installation. Additionally a directory “Image Engineering\LED-Panel” is created in <root>\Users\<username>\AppData\Roaming (example: C:\Users\John_Doe\AppData\Roaming\Image Engineering) to store application settings.
ISO 15781. The software supports all standard image file formats like JPEG, PNG, TIFF, and BMP. The analysis results can be saved as plain text (*.txt) and/or XML files for further processing. Note: Software-based analysis is only available for LED-Panel V5 and LED-Panel V4. Figure 15 Seite 18 von 45...
