### Exposure and Gray Sum Settings During Calibration

Prior to the start of calibration, PCDMIS will set the exposure and gray sum values to the following:

- Exposure: 300

- Gray Sum Min: 10

- Gray Sum Max: 300

These are the settings that will work best for most calibration scenarios. PC-DMIS will restore your original exposure and gray sum values (from before calibration) once the calibration finishes. While gray sum values of 10, 300 are often appropriate for calibration, values of 30, 300 are typical for normal scanning.

Also, the default exposure value of 300 is often not sufficient in rare lighting conditions (such using a V4i with sodium lighting). If PCDMIS has difficulty accepting the arcs during the calibration process, you may need to raise the default calibration exposure value to 400 or so. In cases such as this, modify the PerceptronDefaultCalibrationExposure registry entry located in the NCSesorSettings section of the PC-DMIS Settings Editor. See the PC-DMIS Settings Editor documentation for more information.
