1. Introduction
The purpose of this handbook is to better acquaint the reader with the chal-
lenges of illumination measurements.
In the first part of the book the standards and regulations in this field are
described.
In the second part basics of light measurements are introduced in a simple man-
ner. The most important definitions and terminology are applied, including some
illustrative pictures which help to better understand the topics.
The third and last part presents the measurement methodology. Many useful
hints are given in order to perform fast and accurate measurements.
Two tables of most frequently used illuminance limits are added at the end of
this handbook.
The two illuminance probes BENNING Luxmeter type B and type C are designed
for measurements in conjunction with the installation tester BENNING IT 120.
Please notice also the operating manual of the BENNING IT 120.
It has to be stressed that all BENNING illuminance probes and testers are
designed to perform light measurements in a fast and accurate manner.
All BENNING’s probes are precisely V (λ) adapted and cosine corrected and
they are in complete compliance with the DIN 5032/7 Class C (Luxmeter Type
C) and Class B (Luxmeter Type B) accuracy regulations. The instruments
can perform spot or long term measurements and have recording facilities.
All important data (max, min, avg) can be stored, recalled or compared with
preseted limits. Powerful PC SW packages enable further analysis of test data
and their documentation.
