Introduction
About this document
These guidelines describe how to use the REF800 as a reference light source
and how to do custom calibrations on Viso Systems goniometer products.
Safety information
Warning! This product is not for household use.
Read this manual before installing and operating the REF800, follow the
safety warnings listed below, and study all the cautions in the manual.
Preventing electric shocks
Make sure the power supply is always grounded.
Use a source of AC power that complies with the local building and electrical codes,
and that has both overload and ground-fault protection.
If the controller or the power supply are in any way damaged, defective, wet, or
show signs of overheating, disconnect the power supply from the AC power and
contact Viso Service for assistance.
Do not install or use the device outdoors. Do not spray with or immerse in water or
any other liquid.
Do not remove any covers or attempt to repair the controller or the power supply.
Refer any service to Viso.
Disposing of this product
Viso products are supplied in compliance with Directive 2002/96/EC of the European
Parliament and of the Council of the European Union on WEEE (Waste Electrical and
Electronic Equipment), as amended by Directive 2003/108/EC, where applicable.
Help preserve the environment! Ensure that this product is recycled at the end of its
lifetime. Your supplier can give details of local arrangements for the disposal of Viso
products.

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.
Two physical versions exist –one for mounting on BaseSpion and LabSpion, and one
for mounting on LightSpion:
REF800 FOR
LABSPION/BASESPION
REF800 FOR
LIGHTSPION

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.

▪Test Certificate

The Test Certificate
The REF800 comes with a test certificate as shown below.
Source lifetime
The source lifetime is about 200 hours. Remember to turn off the light source as
soon as possible to preserve the lamp.
Please make sure to include REF800 in all Viso factory calibrations –the REF800 will
be re-characterized to constitute a matched pair with the newly calibrated sensor.
After this, the REF800 will have a prolonged life of another 200 h.
