Installing BQScan

Setup Screenshot The software is straightforward to install and is known to work with Windows XP, Windows Vista and Windows 7. BQScan is a 32-bit programme, but it will work on 64-bit editions of windows.

Starting the programme for the first time requires an activation code, which will be emailed after purchase.

Preparing the Camera

Camera To get useful results, the camera must be set to defined settings with the following procedure.

You need to follow this procedure each time you use BQScan, otherwise the results will not be comparable in any way.

  • Turn camera off
  • Remove lens and attach the plastic protection cap that came with your camera (labeled PC-GF 30)
  • Turn camera on
  • Use the MENU button and set image quality to RAW
  • Set the mode dial to M
  • Set ISO 1600 (use the ISO button and select 1600)
  • Set white balance to daylight (5200K) (WB button, then choose the sun icon)
  • Set exposure time (time value) to 30 seconds (use the dial near the shutter release button until the display reads 30'')
  • Set picture style to 'neutral' (N) (use the picture style symbol-button and choose N)
  • Fully charge battery

Analysing with BQScan

Screenshot It only takes a few moments to analyse objects with BQScan.

Note that you should place the object to analyse as close to the camera's plastic protection cap as possible. Also note that the first time you use the software, you will need to load a second image from the camera. This is used to calibrate the programme with camera-specific parameters.

  • Place the object to measure as close to the camera's plastic cap as possible
  • Take picture
  • Attach camera to computer with its USB cable or place the memory card in your computer's card reader
  • Start the BQScan software
  • Load the image from file or directly from the camera


Atom The intensity of the radiation is closely linked to the distance to the object you are trying to measure. Try to position the object directly in front of the camera's plastic cap. There is no way to blur the image, so using a tripod is not necessary; however, due to the long exposure time of 30 seconds, it is recommended to set the camera down.

Due to most camera cases not being fully light proof, direct exposure to sunlight may result in errors in the analysis. This effect should not occur in rooms with standard illumination.

It is important that the camera is fully charged. If the battery runs out of power while an image is being taken, the camera's mirror may become stuck.

Intense radiation may damage the camera's electronic circuitry.

Due to lack of proper calibration, results and accuracy may vary.
