About Calibration and Light Sources
All Viso light measurement systems are delivered pre-calibrated. The calibration is a
combined spectral and intensity calibration.
All light measurements systems gradually change in time. This is a result of physical
deterioration, temperature variation and contamination. Consequently, regular
maintenance is essential for realistic uncertainty estimates.
Viso recommends checking the calibration status and accuracy with REF800 every
three months. RFE800 is a standard accessory in all new Viso light measurement
systems.
About REF800 - Viso reference lamp
The REF800 light source has its own power supply, and both parts are labelled with
identical calibration date and numbers. Never measure without the original power
supply. The power supply is intended for mains feed 100-240 VAC, 50/60 Hz. The
output (lumen package, intensity, and color properties) is stable regardless of the
type of mains. The power factor will depend on mains.
Right after factory calibration of your light measurement system, the reference light
source is measured, and a certificate is issued. The certificate is part of the delivery.
The certificate
can also be downloaded from Viso’s website using the calibration
number on the labels.
