The plug for the power supply and the main switch are located at the back side of the box. Connect camSPECS with a power socket and switch it on and let it run for a couple of minutes until it reaches a stable temperature. -
Page 4: Spectral Sensitivity (Iq-Led) Module
For documentation purposes the spectral curves can be saved as an image file. 3.1.2 Spectral sensitivity (iQ-LED) module • Start the camSPECS software and switch to module Spectral sensitivity (iQ-LED). • Select the desired Spectral Sensitivity Database. • Select the Dark frame, if desired. -

4.2 Spectral sensitivity (camSPECS) Module 1. Select the calibration file for your camSPECS device. With the '+' and '-' buttons calibration files can be added and removed from the list. Calibration files can be saved to a specified location with the ‘S’... - Page 7 (.txt) and an XML file in the same directory as the original image directory. For the camSPECS version a tile image is saved to the same directory as the origin of the images directory assembled from the single images. Check this image for correct positions of the ROIs or all filters.
