Camera Calibration
After the unit and software are set up, the camera must be calibrated before it can be used. Calibration
must also be performed any time a different computer is connected to the MicroChemi unit. There is a
short camera calibration process of 135 minutes for images that require up to 30 minutes exposure time
and a long camera calibration process of 8 hours for images that require exposure time of over 30
minutes. It is recommended to perform both processes. It is also advised to calibrate the system
annually as part of preventive maintenance procedures.
You can either calibrate the camera immediately after set up and installation or at any other time when
you open GelCapture. Whenever you open GelCapture, if you have not previously calibrated the camera,
the message in step 1 below will be displayed.
To Calibrate the Camera
1 Choose Yes, to start the camera calibration process.
Note that if you click No, calibration files will not be created, images will include background noise
and the Auto Exposure tool will not work properly.
2 When you click Yes to calibrate, a dialog will be displayed asking you to, either:
2.1
Load the camera calibration files from the Camera Calibration CD (supplied in the MicroChemi
packaging), OR
2.2
Create new camera calibration files.
