B3 Configuration
B3.1 Program Selection
With the program key you can skip between the programs, i.e. every pressing the
program key switches to the next program. The following programs are at choice:
•
P1 Single-angle measurement
•
P2 Difference measurement
•
P3 Three-angle measurement
•
P7 Memory print (not for REFO 3)
•
P8 Standard check program
•
P9 Input of standard number and calibration values
The selected program is indicated on the display above the program key. Program
P7 can only be selected if a printer is connected. Programs P8 and P9 can only be
selected with the instrument placed on the standard.
B3.2 D- and M-Modes (for REFO 3-D only)
REFO 3-D has two working areas. D-mode is meant for DIN-measurements and M-
mode for high-gloss measurements. REFO 3-D selects the correct mode automati-
cally after calibration. In D-mode standard A is used for calibration, in M-mode the
metal standard is used. The current mode is indicated during the calibration by letter
D or M before the standard number.
