Character length: 8 bits
Stop bits: 1 bit
Parity: NONE
Manual mode: Measurement data can be output (for each measurement at time of measurement; for all selected measurements stored on memory card)
REMOTE mode: Command input, data output, input of messages for display only
Comment can be input using bar code reader |
| Display data |
Spectral reflectance: Graph or numerical values
Colorimetric values: Numerical absolute color and/or color difference values in the following notations: XYZ, Yxy, L*a*b*, L*C*h, Hunter Lab, Munsell, MI (Metamerism Index), CMC (f:c), WI (ASTM E313), WI (CIE), YI (ASTM E313), YI (ASTM D1925), IS0 Brightness (IS0 2470) IS0 Status A and Status T densities
Data or messages transmitted from a computer connected to the RS-232C terminal can also be displayed in REMOTE mode. |
| Measurement conditions |

llluminants F2, F6, F7, F8, F10, F l l (TL84), and F12 (Ultralume 3000)
2 illuminants can be selected.
Observer: CIE 2' and 10' Standard Observers
Measurement conditions stored on installed optional memory card given priority. |
| Data memory |
Built-in memory: Up to a total of 200 sets of data (measurement and target color) including a maximum of 199 sets of target color data With optional 128KB memory card: Up to a total of 1350 sets of data including a maximum of 1349 sets of target color data With marketed 256KB SRAM card: Up to a total of 2700 sets of data including a maximum of 2699 sets of target color data |
| Target color data |
Target color data can be set by measurement, by data input using keys, or by data input from computer connected to RS-232C terminal
Target color data can be temporarily deleted and later recovered.
Automatic target color selection function determines which target color is closest to measured color |
