Overview
1.1 Product Overview
The 3423 is suited for a wide range of
applications involving illumination equipment,
lighting work and facility management.
The instrument has five measurement ranges,
20 lx to 200,000 lx, so it can measure the wide
range of illuminance.
It can measure, with the detector separated
from the display and has a large LCD easy to
read in the display, for user's convenience.
Moreover, the backlight allows to take readings
easily under the low illuminance. (The display is
held when the backlight turns on and the
backlighting has no effect on the measurement. )
By using the silicon diode and optical filter in
the detector, the visual perception is corrected
so that the perception of colors is close to
human perception. The instrument has a
microcomputer and can perform the auto range,
one-touch zero adjustment of analog output. An
AC adapter is also available, as well as
batteries, and useful for long-time
measurement.
