Thermography System VarioCAM

9. Introduction

User Manual © InfraTec GmbH 2016 69

In order to prevent an exceeding of the limits of the set calibration range, the option "Automatic"* of the

menu item "Calibration" can be activated to automatically adjust the calibration settings to the currently

observed scene. The toggle time of the calibration range depends on the maximum temperature of the

current scene. If the temperature exceeds the maximum temperature of the current calibration range, the

camera automatically switches to the next higher range.

When using the VarioCAM

HD for mobile applications and in the event of a constantly changing

scene, we recommend deactivating the automatic measuring range setting (factory setting).

Depending on the VarioCAM

HD model, higher frame rates* can be used. Therefore, fast changing

temperature differences and mobile objects can be visualised. For this, the size of the displayed image is

reduced. The sub frame formats are only for cameras with XGA detectors of (1.024 x 768) IR pixels that

can be activated in the menu item “image format”. Alternatively, the settings for sub frame or calibration

range can also be changed with the remote control menu of the Software IRBIS

3 online. The

functionality of VarioCAM

HD is limited in the sub frame mode. Data storage in the sub frame mode is

only possible in conjunction with IRBIS

3 online.

The VarioCAM

HD with detector format (640 x 480) does not display images on display/searcher or

CVI/VGA. The use of the sub frame mode with this camera model is only possible with GigE-Interface.

The use of sub frame modes influences the date shown in chapter XX on page XX.

The following image formats (IR pixels) and frame rates are selectable:

Detector formats XGA (IR pixels) VGA (IR pixels)

Full screen (1.024 x 768) 30 Hz (640 x 480) 60 Hz
