Using Lumidisc (Optional Accessory)
The Lumidisc is used to measure the light falling on green-screen walls, paintings or at
art. It is also used to adjust lighting ratios with multiple light sources (
➡
P28) or when
taking Lux and Footcandle measurements (
➡
P24,
➡
P27). To measure light with
the Lumidisc, slide the Lumisphere mounting to the right (same as if measuring reected
light), then insert, at an angle, section B of the Lumidisc into slot A of the meter body and
press down on the strap eyelet C to secure the Lumidisc.

The Lumidisc is removed in reverse order to the mounting method.
At this time the strap eyelet of the Lumidisc should be pulled up and away
from the meter body.
WARNING
●
Keep the Lumidisc
(
Optional Accessory
)
out of reach of Infants or toddlers,
as swallowing such objects can cause suffocation.
NOTICE
● Be sure to handle the Lumidisc correctly to prevent damage that may occur if mounting
or removal is incorrect.
● When the Lumidisc is not being used, do not attach it at the right of the Lumisphere for
storage. This will block light falling on the Lumisphere and affect the accuracy of the
measurement.
● The Lumidisc is an important light receiving unit. Please handle with care and try not to
mark or soil. Wipe Lumidisc with a dry soft cloth if it becomes dirty. Never use organic
cleaners (like thinner or benzene) to clean Lumisphere.
