Output data are measurement conditions and various measurement color values.
There are three output formats as follows depending on the measurement mode.

The value of the above table is a design value.
It is likely to differ somewhat in each product.
･
T* : Measurement count
TF : 1 measurement,
TS : Average of 5 measurements
･
R* : Measurement range
RA : AUTO,
RM : MANUAL
･
Rn : Measurement range used for measurement
n
: 1 to 5
･
U* : unit
UC : cd/m
2
･
Fn : Measuring field
F1 : 0.1°, F2: 0.2°, F3: 1°, F4: 2°, F5: 3°
* _ indicates a space.
* # indicates a numerical value.
* The carriage return code (0x0d) is indicated by CR.
* When the CR(0x0d) carriage return code is not read by the computer, this instrument judges that
transmission is incomplete, and the instrument enters a non-operable state.
※
The values in ranges 2 to 5 are
values obtained by multiplying
10X,
100X,
1000X,
and
1000X, respectively.
