Operating Instructions
Features
The cal-COLOR 400 is ergonomically
designed for easy operation featuring single
button operation; auto ranging display and
auto power “OFF”. The cal-COLOR 400
comes complete with a calibration
certificate traceable to NIST (National
Institute of Standards and Technology, USA)
standards, integral stand, operation
instructions, carrying case and 9 volt battery.
Controls
To switch on the cal-COLOR 400 click the
front “ON” button. The cal-COLOR 400 will
run through its initialization sequence, and
the auto ranging LCD will display
illuminance in foot-candles (fc) or lux, color
temperature in Kelvin (K), and chromaticity
co-ordinates in x and y. The LCD is read
directly without multipliers, except when
the illuminance reading is followed by a “k”
indicating units of 1000.
Eg. 3.89 kfc reading = 3.89 kilofootcandles
The reading is calculated as 3.89 x 1000 =
3890 fc.
The cal-COLOR 400 allows you to easily
measure and read the LCD simultaneously.
If you wish to “HOLD” the reading, press
and hold the ON button, and release of the
button returns function to “AUTO
RANGING” mode.
The cal-COLOR 400 features auto power
“OFF” after five (5) minutes of non-use.
To switch between foot-candles (fc) and lux
units, double click the “ON” button.
How to measure
The cal-COLOR 400 provides accurate
measurements when the operational
guidelines are followed. The cal-COLOR 400
measures the light that falls onto a surface
from a light source in foot-candles (fc) or lux
units, color temperature in Kelvin (K), and
chromaticity co-ordinates in x and y.
When held at arm's length in a comfortable
reading position, the angled light sensor is
automatically positioned horizontally and
ready to measure.
When taking measurements from a table or
desk surface, hold the instrument near the
surface so the light sensor is parallel to this
surface. This will allow you to comfortably
read the measurements from the cal-
COLOR 400 LCD.
When taking illuminance measurements at
a vertical surface, repeat the operation so
the light sensor is parallel to the surface.
This allows for comfortable reading of the
LCD, while simultaneously taking the
measurements.
A convenient integral support stand that
swings out from the cal-COLOR 400
enables remote measurements from a flat
surface. This permits the angled light sensor
to be parallel to the surface, and allows you
to read from long distances. The cal-COLOR
400’s large LCD display can be read from a
distance of 15 feet or more. While using
