INTRODUCTION
The
AccuProbe HH06
1
color meter is a hand-held instrument capable of performing a
number of color measurement and identification functions. The instrument may be
operated both as a portable unit using standard nine-volt batteries, or used under control
of a personal computer using the standard RS232 interface and connected to a power
supply.
AccuProbe HH06
instruments include modern flash-programmable memory
that may be programmed at the factory or by a qualified dealer to perform a range of
color measurements. When programmed at the factory with data from a commercial
color identification system, the instrument
can be used to pick the color closest to a
measured sample from a commercial color reference system, or to pick colors, for
example, “lighter than” but “next to” the closest color. By picking colors along specific
color directions (for instance: “lighter”, “darker”, “greener”, “redder”, “yellower”, and
“bluer”) the unit can select the “neighborhood” of a target color in a color system. The
instrument can be programmed by a qualified distributor to pick colors from any custom
set of colors for which target reflectance is known. When used in conjunction with a
laboratory spectrophotometer operating with a personal computer (PC), the
AccuProbe
HH06
color meter can be programmed to function as a Pass/Fail meter with reference to
one or more color standards.
In relation to physical color standards, or in conjunction with numerical reflectance
standards (from a laboratory spectrophotometer), the unit performs as a color difference
meter that provides color differences using several modern color difference formulas.
When operated as a portable unit, the
AccuProbe
HH06
color meter can “remember”
every measurement. These measurements may subsequently be extracted by a personal
computer.
The instrument can act as a color memory. It will “remember” the colors of
painted walls, wallpaper, pictures, … and these colors can be recalled later on the display
of the instrument or using a personal computer. If the instrument is used to measure the
same material a number of times, it serves as a data collection tool for statistical quality
control. Because the color meter can remember all of the information from each
measurement, it can also be used as a personal Pass/Fail meter by manufacturing
personnel, while numerical color coordinates may be extracted periodically for statistical
quality control.
Finally, the instrument operates as a stand-alone colorimeter, reporting color coordinates
in several forms, including whiteness and yellowness indices. The basic instrument
includes color picking, color difference, and colorimetry features. Advanced features are
added by means of a dealer-installed PCMIA memory card, and personal computer
programs.
