Checking the calibration status
With the reference lamp you can quickly check your calibration status:
•
Check whether the total flux in lumen and peak candela is close to the
original values
•
Check whether the shape of the spectrum is close to the original shape.
•
Check whether the spectrum looks spiky or jagged.
If you are not happy with the result, the system needs to be calibrated. Viso
recommends calibration every year, or minimum every 2 years. Viso provides
calibration service, or you may do your own calibrations using the Viso CALI-T50 or
other traceable calibration light sources.
Check-up Procedure
•
Move the sensor to the distance specified in the lamp certificate
•
Place the Reference 800 with the indicator (the oblong hole in the base)
upwards
•
Do not preheat the light source before measurement
•
Centre the light source in the gonio.
•
Set the measuring distance to the exact distance specified on the lamp
certificate
•
Start measurement normal measurement. In the stabilization window,
choose “1,0% in 15 min.” and let the measurement finish by itself.
•
Compare vales of lumen (max. +/-4% deviance) and intensity (max. +/-2,5%
deviance) with values in the lamp certificate.
•
Check the spectral intensity distribution graph for shape.
•
If mismatch is found, sensor calibration in due.
