[. . . ] PREPARING METER FOR OPERATION Battery check: Place a battery in battery chamber correctly, Then b. c. mark and bar symbols and switch the meter ON are displayed for a second. [. . . ] Switch the meter ON and point Lumidisc directly toward center of main light. Difference between EV numbers of main and fill-in lights becomes contrast ratio (refer to Table 1). For measuring luminance (Lux): Set ISO sensitivity to ISO 100 regardless of your film speed. Place Lumidisc parallel with the measured surface and read EV number in the same manner as for other measurements. As to Lux value corresponding to the measured EV number, please refer to Table 2. Reflected light measurement: Mount Lumigrid to swivel head. Switch the meter ON and point Lumigrid directly toward part of subject to be measured. Measure reflected light from main point of subject as close as possible to the subject. Use adequate care in this case that the meter shadow does not interfere with the light to be measured. Calculation dependent upon change of film speed can be made by pressing either side of UP/DOWN key while depressing ISO selecting key. Calculation dependent upon change of shutter speed can be made by pressing either side of UP/DOWN key only. Conversion of measuring mode can be made by pressing F/EV selecting key. Measuring range: When measuring range is exceeded, F-stop or EV number will be replaced E. o (error-over) or E. u (error-under) mark. [. . . ] It makes you possible to measure reflected light of distant subject without going up close to the subject, or to check reflected light from small part of the subject.
