C7 Continual Gloss Measurement
(REFO 3-D only)
With the continual gloss measurement program, measurements are made automati-
cally in 3 second intervals.
In this measurement mode it is not possible to transfer data through the interface or
the internal memory. This program function is enables the measurement of gloss
differences over a large surface with the reflectometer.
•
Switch on REFO with the Meas/ON key
•
Select program P4 with the program key
•
Select measurement angle with the angle select key (the selected angle is
shown in the display)
•
Place the REFO on the sample
•
Press Meas/ON to start continual measurement
•
Press Meas/ON again to end the measurement process
C8 Check Program for Standard
Check program P8 checks the function of REFO 3-D. The check is performed as
follows:
•
Place REFO on the standard
•
Turn on REFO with key Meas/ON
•
Select program P8 with the program key
Now you can measure the standard. In addition to the ordinary single- and three-
angle measurements, the statistics function can be used, too. If the measurings are
not identical with the calibration values, the calibration is bad.
C9 Printer
All measuring and calibration values can be documented with an optional printer.
There are two types of prints, i.e. protocol print and memory print (only REFO 3-D).
In the protocol print, all values are printed at once. In the memory print, however, the
entire memory is printed. The print-out shows the measurings, the number of the
measurement and the identification of the measuring values as per the following ta-
ble:
