Both ColorBurst and ColorDome Ganzfeld Stimulators have a built-in Auto-Calibration feature. This feature serves two purposes, it checks the status of calibration by measuring flash brightness and uses these values to adjust the LED output, ensuring accurate light intensities for patient testing. Follow these instructions to setup your Auto-Calibration feature.
Step 1. ENABLE AUTO-CALIBRATION FEATURE
Open the Software -- Configure System -- Program -- Global -- Debug Mode
Set Debug Mode to 1
Close & Save
Step 2. RUN AUTO-CALIBRATION
Open any protocol that uses the ColorDome or ColorBurst stimulator
Turn out the rooms lights or cover the Dome with a dust cover / opaque material
We do this because Ganzfeld stimulators have built in photocells which measure light; in covering the opening and darkening the environment, we make sure to only pick up the light being output by the device and not the ambient light.
When the calibration window appears, click Calibrate.
Step 3. EVALUATE CALIBRATION STATUS
Check the Factor column
1.00 = 100% = Optimum calibration
1.20 = 20% deviation
0.80 = 20% deviation
If two or more colors are past 20% deviation, consider scheduling a calibration service soon.
1.5 = 50% deviation
0.5 = 50% deviation
If any of the colors are past 50% deviation, calibration is long overdue and you are at risk for seeing calibration-related changes in clinical data.
Performing this Auto-Calibration will temporarily adjust the values of the light output; this will need to be redone each time the software is opened from scratch. The more time has passed since a formal calibration, the more critical it is to use this feature.
Step 4. CONTACT SUPPORT TO ARRANGE CALIBRATION SERVICE
Continue to routinely use this Auto-Calibration feature.
When two or more colors pass the 20% deviation range, call or email Diagnosys Support to schedule a calibration service.
