Operating Instructions REFO 3 / REFO 3-D Meas./On-key Figure 2: REFO side view B2 Initial Start-Up B2.1 Charging the batteries The electrical power supply is provided by four Ni-Cd batteries, type LR6 AA Mignon. They are located in the battery compartment at the rear of the instrument. In order to charge the batteries • plug the charger plug into the mains/charging socket • connect the charger to the socket-outlet The batteries are loaded automatically within 14 hours.

Operating Instructions REFO 3 / REFO 3-D C Applications C1 Calibration It is recommended to calibrate at least once a day or after extended breaks. Before starting to calibrate make sure that the standard is clean and the cloth removed.
Operating Instructions REFO 3 / REFO 3-D C4 Difference Gloss Measurement Difference measurement means measuring against a reference. The measured difference between reference and sample is the indicated measured value. • Turn on REFO with key Meas/ON • Use the program key to select program P2 • Use the angle selector key to select the viewing angle (the selected angle is indicated on the display) • Place REFO on the reference • Press key Meas/ON to measure the reference.
Operating Instructions REFO 3 / REFO 3-D C6 Statistics In all of the three programs P1, P2 and P3 you can acquire and evaluate entire setoff measurements with the following statistical values calculated: • mean value • standard deviation • coefficient of variability For statistical evaluation of a set-off measurement, procede as follows: • Turn on REFO with key Meas/ON • Use the program key to select program P1, P2 or P3 • Select the viewing angle for programs P1 and P2 with the angle selector key (for pro
Operating Instructions REFO 3 / REFO 3-D C7 Continual Gloss Measurement (REFO 3-D only) With the continual gloss measurement program, measurements are made automatically 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.
