Terminology
Correction Factor:
This refers to three factors, KX, KY and KZ, for correcting tristimulus values.
Area Correction Factor:
When an arbitrary area is specified on the xy and u'v' chromaticity diagrams, these factors are for
correcting values that fall within that area.
Correction Reference Sample:
This is a sample for determining correction factors.
(e.g. a monitor TV whose tristimulus values have been valued as corrected through
spectrometry)
Standard sample:
This is a sample used as the standard for color matching.
White Board:
This is a white board with good diffusion, made of barium sulfate, etc.
Prompt:
A message output by the instrument for instructing the operator to perform some operation.
RAM (Random Access Memory):
Memory that can be read and written. RAM can be thought of as volatile memory whose contents
are lost when the instrument is turned OFF.
EEPROM (Electric Erasable Programmable Read Only Memory):
This is ROM whose contents can be erased electrically. EEPROM can be thought of as non-
volatile memory that does not require a battery.
Local Mode:
This is the normal measurement status.
In this mode, the instrument is operated by the panel switches, and cannot be controlled by an
external PC.
Remote Mode:
In this mode, the instrument is controlled by an external PC via the interface. It can also be
controlled by its panel switches.
Function Mode:
This mode is for displaying and changing the data stored in the instrument's memory.
Direct Connection Function:
This function enables correction between 2 luminance colorimeters that are directly connected by
an RS-232C cable.
